You’ll find the typical push-pull vacuum tube amplifier to be most commonly based upon a pentode tube – the 6550 or one of its variants being one popular choice. These push-pull amplifiers can provide high power output, but at the expense of ultimate transparency. The single-ended tube amplifier, on the other hand, often provides wonderful midrange transparency, but with the severe drawback of low power output and less than stellar reproduction of the frequency extremes.\u003c\/p\u003e\n\u003cp\u003eThe REX II Power amplifier is a different beast altogether. Its design is fully symmetrical from beginning to end. You can think of it as two single-ended amplifiers per channel, with their waveforms summed at the output transformer. The beauty of this design is that no direct current flows through the output transformer. Why is this critically important? This fact allows the output transformer to be a truly wide bandwidth design, while reducing low frequency distortion.\u003c\/p\u003e\n\u003cp\u003eWhen you combine this fully symmetrical circuit with a high-current, all-triode, zero-feedback, fully balanced design, the drawbacks of push-pull and single-ended designs are banished. The REX II Power amplifier combines high-power output, beautiful midrange texture, and great extension at the frequency extremes.

The current source is an integral, albeit extremely important, part of a differential circuit. Its quality to a large degree determines the ultimate performance of a gain stage. As opposed to a more common resistive solution, the vacuum-tube current source is much closer to an ideal model. The benefits of implementing dual current-sources within the REX II Power amplifier are several-fold:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eThe linearity of the gain stage improves.\u003c\/li\u003e\n\u003cli\u003eThe adjustments for the first and second gain stages become independent and therefore more easily optimized.\u003c\/li\u003e\n\u003cli\u003eThe tube current source components operate at much lower stress level, thus improving reliability.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eIn addition, more than one type of vacuum tube can be used in the second-stage current-source. This allows each user to fine tune the Rex II Power amplifier’s sound to best meet their individual needs. No matter which choice the user selects, this dual current source implementation extends the performance of the REX II Power amplifier to another level. The final result is an impressive improvement in the palpability of the phantom musical event.\u003c\/p\u003e\n\u003ch3\u003e80 Watts per channel (Stereo) 160 Watts per channel (Mono)\u003c\/h3\u003e\n\u003cp\u003eThe REX II Power amplifier is a high-current all-triode design that offers a robust 80 watts per channel in the stereo version or a compelling 160 watts per channel as a mono block. The 6C33C-B triode output tube used in the REX II Power amplifier offers many times the current delivery of the more common 6550 tube used in more traditional push-pull designs. High impedance vacuum tubes like the 6550 require far more complicated output transformers than the low impedance 6C33C-B vacuum tube. Consequently, the REX II Power amplifier is quite comfortable driving low impedance loads. You can simply choose the stereo or monoblock version based upon your choice of speaker and room size. The high-current delivery of the REX II Power amplifier will give you the assurance of driving a difficult load with ease.\u003c\/p\u003e\n\u003ch3\u003eIntelligent auto-bias \u0026amp; electronic protection\u003c\/h3\u003e\n\u003cp\u003eThe advanced design of the REX II Power amplifier eliminates the traditional headache associated with most vacuum-tube power amplifiers; the constant need to set and readjust the proper bias of the output tubes. The REX II Power amplifier features an intelligent automatic bias circuit that adjusts for changing line voltage and aging tubes. For convenience, the intelligent automatic bias circuit contains LED indicators that show the status of each individual output tube. This auto-bias circuit also ensures that your REX II Power amplifier sounds wonderful within the first few minutes of listening. This is indeed very different from manually biased designs that must be adjusted for their thermally warm set point - and thus sound too cold and clinical before their tubes are fully warmed up.\u003c\/p\u003e\n\u003cp\u003eBalanced Audio Technology extends the plug and play nature of the REX II Power amplifier further with a novel “fuse-less” protection circuit. This electronic protection circuit eliminates the power supply rail fuses to provide both a more refined sonic performance, as well as a very user-friendly experience. All the user has to do in the event of an output tube being over-stressed is to flip the power switch; it doesn’t get any easier than that!\u003c\/p\u003e\n\u003cp\u003eNo tubes to bias. No tube fuses to replace. This is the best of modern engineering applied to vacuum-tube amplifier design.\u003c\/p\u003e\n\u003ch3\u003eIntelligent power upgrade\u003c\/h3\u003e\n\u003cp\u003eThe REX II Power amplifier is easily upgraded from the stereo version to monoblock configuration. Unlike competing designs, there is no need for the user to trade their amplifier in to obtain more power. With the REX II Power amplifier, the user can simply convert their existing REX II to a monoblock, and then order a second REX II monoblock to match. Technically, the stereo to monoblock conversion is accomplished by simply paralleling the inputs and outputs. This means that “the sound” only gets better as monoblock current delivery goes up by a factor of two and the monoblock noise floor drops appreciably as well.\u003c\/p\u003e\n\u003cp\u003eA little known fact is that you can even parallel the REX II monoblocks by daisy-chaining them together. Do you want 320 watts per channel of high current, zero feedback, fully balanced power? Just use two REX II monoblocks per side!\u003c\/p\u003e\n\u003ch3\u003eSummary\u003c\/h3\u003e\n\u003cp\u003eThe REX II Power amplifier from Balanced Audio Technology is the culmination of nearly two decades of research into what constitutes the ultimate vacuum-tube power amplifier. Right out of the box, it is unlike most vacuum tube power amplifiers in being a fully balanced symmetrical design. This balanced symmetry, when combined with a high current, zero-feedback, all triode, dual vacuum-tube current source topology makes the REX II Power amplifier special indeed. Add the plug and play nature of automatic biasing and automatic protection to the list, and you have a thoroughly modern vacuum-tube amplifier that, by design, performs well above the rest.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Per Channel (8 Ω \/ 4 Ω):\u003c\/strong\u003e 80 W \/ 80 W \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput in Mono Configuration (8 Ω \/ 4 Ω):\u003c\/strong\u003e 160 W \/ 160 W \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 5 Hz to 200 kHz\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTHD (Full Power):\u003c\/strong\u003e 3.0 % \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGain (Nominal into 8 Ω):\u003c\/strong\u003e 26 dB\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance (Mono):\u003c\/strong\u003e 108 kΩ \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNumber of Power Cords:\u003c\/strong\u003e 1\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance (Stereo):\u003c\/strong\u003e 215 kΩ \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Consumption (Idle \/ Full):\u003c\/strong\u003e 500 W \/ 1000 W\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTube Complement:\u003c\/strong\u003e 4 x 6H30, 6 x 6SN7, 2 x 6V6, 4 x 6C33C-B \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 17\" x 9\" x 24\"\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRemote Control:\u003c\/strong\u003e No \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 100 lb\u003c\/p\u003e","brand":"Balanced Audio Technology","offers":[{"title":"Default Title","offer_id":21832624389,"sku":"REXII-AMP OPEN","price":12995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/products\/BAT_REX_II_Power_Amp_Silver_Front_2048x2048_cf28c537-d811-41ef-a782-1ec3e224ce6c.jpg?v=1741632414"},{"product_id":"zesto-audio-eros-300-monoblock-poweramps-pair","title":"Zesto Audio Eros 300 Monoblock Poweramps (pair) (OPEN)","description":"\u003ch1\u003eZesto Audio Eros 300 Mono Power Amplifiers (pair)\u003c\/h1\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cfigure style=\"text-align: center;\"\u003e\n\u003cblockquote\u003e\n\u003cspan\u003e“\u003c\/span\u003eConservatively rated at 150 W into 4 and 8 Ohms, the Zesto 300 features pure Class-A circuitry and uses six KT-88's per monoblock.

It took over 3 years to develop the Eros and 79 circuit designs later. I always look at the design from two points of view, as an audio engineer and an electrical perspective. Each design phase is based on a 50\/50 balance between the technical spec and listening to each component change.  Ultimately, the final design must sound good because who listens to sign waves anyway.\u003c\/p\u003e\n\u003ch4\u003eClass A amplifier design\u003c\/h4\u003e\n\u003cp\u003eClass A has less cross-over distortion and therefore is more musical.

Additional NA009 transistors are used in the fully regulated power supply, ensuring the very best performance.\u003cbr\u003e\u003cbr\u003eA variable speed, virtually noiseless cooling fan is mounted on a large internal heat sink providing long-term stability and the ability to swing a massive 500 VA on transients. The NAP 300 is stable into any load and able to drive a 2-Ohm load for long periods of time.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePower Output (8 Ω): \u003c\/strong\u003e90 W \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInputs:\u003c\/strong\u003e 2 x XLR\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 18 kΩ\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGain:\u003c\/strong\u003e +29 dB\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMinimum Load Impedance:\u003c\/strong\u003e 2 Ω \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpeaker Outputs:\u003c\/strong\u003e 4mm “banana” sockets\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTransient Power:\u003c\/strong\u003e 500 VA\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions (HWD):\u003c\/strong\u003e 3.4\" x 17\" x 12\" (87 x 432 x 314 mm)\u003c\/p\u003e","brand":"Naim Audio","offers":[{"title":"Default Title","offer_id":9422507606076,"sku":"NAIMNAPS300-DR","price":12700.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/files\/nap300_2.jpg?v=1741631962"},{"product_id":"zesto-audio-bia-120-stereo-poweramp","title":"Zesto Audio Bia 120 Stereo Poweramp","description":"\u003ch1\u003eZesto Audio Bia 120 Stereo Power Amplifier\u003c\/h1\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cfigure style=\"text-align: center;\"\u003e\n\u003cblockquote\u003e\n\u003cspan\u003e“\u003c\/span\u003eZesto's Bia 60Wpc, Class A, all-tube power amplifier, with styling to match the company's Leto linestage and Andros phonostage, brings the designers the trifecta.

You’ll find the typical push-pull vacuum tube amplifier to be most commonly based upon a pentode tube – the 6550 or one of its variants being one popular choice. These push-pull amplifiers can provide high power output, but at the expense of ultimate transparency. The single-ended tube amplifier, on the other hand, often provides wonderful midrange transparency, but with the severe drawback of low power output and less than stellar reproduction of the frequency extremes.\u003c\/p\u003e\n\u003cp\u003eThe REX II Power amplifier is a different beast altogether. Its design is fully symmetrical from beginning to end. You can think of it as two single-ended amplifiers per channel, with their waveforms summed at the output transformer. The beauty of this design is that no direct current flows through the output transformer. Why is this critically important? This fact allows the output transformer to be a truly wide bandwidth design, while reducing low frequency distortion.\u003c\/p\u003e\n\u003cp\u003eWhen you combine this fully symmetrical circuit with a high-current, all-triode, zero-feedback, fully balanced design, the drawbacks of push-pull and single-ended designs are banished.

It is a design without compromise.\u003c\/p\u003e\n\u003ch3\u003eVacuum-tube current sources\u003c\/h3\u003e\n\u003cp\u003eCompared to the previous generation of REX products, the REX II Power amplifier substantially improves its gain stage architecture by extending the benefits of vacuum-tube current sources to include both the first and second gain stages of the circuit design. The current source is an integral, albeit extremely important, part of a differential circuit. Its quality to a large degree determines the ultimate performance of a gain stage. As opposed to a more common resistive solution, the vacuum-tube current source is much closer to an ideal model. The benefits of implementing dual current-sources within the REX II Power amplifier are several-fold:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eThe linearity of the gain stage improves.\u003c\/li\u003e\n\u003cli\u003eThe adjustments for the first and second gain stages become independent and therefore more easily optimized.\u003c\/li\u003e\n\u003cli\u003eThe tube current source components operate at much lower stress level, thus improving reliability.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eIn addition, more than one type of vacuum tube can be used in the second-stage current-source. This allows each user to fine tune the Rex II Power amplifier’s sound to best meet their individual needs. No matter which choice the user selects, this dual current source implementation extends the performance of the REX II Power amplifier to another level. The final result is an impressive improvement in the palpability of the phantom musical event.\u003c\/p\u003e\n\u003ch3\u003e80 Watts per channel (Stereo) 160 Watts per channel (Mono)\u003c\/h3\u003e\n\u003cp\u003eThe REX II Power amplifier is a high-current all-triode design that offers a robust 80 watts per channel in the stereo version or a compelling 160 watts per channel as a mono block. The 6C33C-B triode output tube used in the REX II Power amplifier offers many times the current delivery of the more common 6550 tube used in more traditional push-pull designs. High impedance vacuum tubes like the 6550 require far more complicated output transformers than the low impedance 6C33C-B vacuum tube. Consequently, the REX II Power amplifier is quite comfortable driving low impedance loads. You can simply choose the stereo or monoblock version based upon your choice of speaker and room size. The high-current delivery of the REX II Power amplifier will give you the assurance of driving a difficult load with ease.\u003c\/p\u003e\n\u003ch3\u003eIntelligent auto-bias \u0026amp; electronic protection\u003c\/h3\u003e\n\u003cp\u003eThe advanced design of the REX II Power amplifier eliminates the traditional headache associated with most vacuum-tube power amplifiers; the constant need to set and readjust the proper bias of the output tubes. The REX II Power amplifier features an intelligent automatic bias circuit that adjusts for changing line voltage and aging tubes. For convenience, the intelligent automatic bias circuit contains LED indicators that show the status of each individual output tube. This auto-bias circuit also ensures that your REX II Power amplifier sounds wonderful within the first few minutes of listening. This is indeed very different from manually biased designs that must be adjusted for their thermally warm set point - and thus sound too cold and clinical before their tubes are fully warmed up.\u003c\/p\u003e\n\u003cp\u003eBalanced Audio Technology extends the plug and play nature of the REX II Power amplifier further with a novel “fuse-less” protection circuit. This electronic protection circuit eliminates the power supply rail fuses to provide both a more refined sonic performance, as well as a very user-friendly experience. All the user has to do in the event of an output tube being over-stressed is to flip the power switch; it doesn’t get any easier than that!\u003c\/p\u003e\n\u003cp\u003eNo tubes to bias. No tube fuses to replace. This is the best of modern engineering applied to vacuum-tube amplifier design.\u003c\/p\u003e\n\u003ch3\u003eIntelligent power upgrade\u003c\/h3\u003e\n\u003cp\u003eThe REX II Power amplifier is easily upgraded from the stereo version to monoblock configuration. Unlike competing designs, there is no need for the user to trade their amplifier in to obtain more power. With the REX II Power amplifier, the user can simply convert their existing REX II to a monoblock, and then order a second REX II monoblock to match. Technically, the stereo to monoblock conversion is accomplished by simply paralleling the inputs and outputs. This means that “the sound” only gets better as monoblock current delivery goes up by a factor of two and the monoblock noise floor drops appreciably as well.\u003c\/p\u003e\n\u003cp\u003eA little known fact is that you can even parallel the REX II monoblocks by daisy-chaining them together. Do you want 320 watts per channel of high current, zero feedback, fully balanced power? Just use two REX II monoblocks per side!\u003c\/p\u003e\n\u003ch3\u003eSummary\u003c\/h3\u003e\n\u003cp\u003eThe REX II Power amplifier from Balanced Audio Technology is the culmination of nearly two decades of research into what constitutes the ultimate vacuum-tube power amplifier. Right out of the box, it is unlike most vacuum tube power amplifiers in being a fully balanced symmetrical design. This balanced symmetry, when combined with a high current, zero-feedback, all triode, dual vacuum-tube current source topology makes the REX II Power amplifier special indeed. Add the plug and play nature of automatic biasing and automatic protection to the list, and you have a thoroughly modern vacuum-tube amplifier that, by design, performs well above the rest.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Per Channel (8 Ω \/ 4 Ω):\u003c\/strong\u003e 80 W \/ 80 W \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput in Mono Configuration (8 Ω \/ 4 Ω):\u003c\/strong\u003e 160 W \/ 160 W \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 5 Hz to 200 kHz\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTHD (Full Power):\u003c\/strong\u003e 3.0 % \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGain (Nominal into 8 Ω):\u003c\/strong\u003e 26 dB\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance (Mono):\u003c\/strong\u003e 108 kΩ \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNumber of Power Cords:\u003c\/strong\u003e 1\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance (Stereo):\u003c\/strong\u003e 215 kΩ \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Consumption (Idle \/ Full):\u003c\/strong\u003e 500 W \/ 1000 W\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTube Complement:\u003c\/strong\u003e 4 x 6H30, 6 x 6SN7, 2 x 6V6, 4 x 6C33C-B \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 17\" x 9\" x 24\"\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRemote Control:\u003c\/strong\u003e No \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 100 lb\u003c\/p\u003e","brand":"Balanced Audio Technology","offers":[{"title":"Default Title","offer_id":42418467930296,"sku":"REX-II-MONO-BLK-OPEN","price":23995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/files\/BAT_REX_II_Power_Front.jpg?v=1741630176"},{"product_id":"mark-levinson-no-5302-dual-mono-amplifier","title":"Mark Levinson No. 5302 Dual Mono Amplifier","description":"\u003ch1\u003eMark Levinson No. 5302 Dual Mono Amplifier\u003c\/h1\u003e\n\u003ch3\u003eA 135 Wpc bridgeable class AB amp that doubles into 4 Ohm and is 2 Ohm stable. Designed and handcrafted in the US.\u003c\/h3\u003e\n\u003cp\u003eThe Mark Levinson No. 5302 is a fully discrete, direct-coupled, dual monaural class AB power amplifier.
