Artistic expression with sound!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOh, and by the way, it is also a Line-Level Preamplifier!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThere are fifteen independent controls available, each of which was exhaustively developed for convenient adjustability and aural variety. Two selectable stereo RCA jack pairs receive the input signals. Even these RCA jacks are of our own design. Teflon® insulated and gold plated, we have been producing these excellent RCA jacks since the mid-1990s.\u003c\/p\u003e\n\u003cp\u003eThe volume is controlled on the facia by the sexy front thumb wheel and also by the included Radio Frequency remote control, both of which operate a precision stepped relay ladder matrix attenuator in half dB steps.\u003c\/p\u003e\n\u003cp\u003eThe RF remote can be operated anywhere in the home, even through walls or cabinetry, especially useful when using the unit as a stand-alone preamplifier. Next to the front volume control wheel you’ll find the Mute switch to instantly kill the signal. Spinning the volume wheel all the way to minimum also mutes the signal. There is also a user adjustable Headphone Overload Protection System which declares maximum output level to protect precious headphones and your ears!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAnd you know how maddening it is to try to listen to a mono LP record on headphones - which is why we have provided a MONO switch!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn case your source needs some correction or if your own ears do not hear equally, we have included a Balance Control which can swing the signal up to 72dB either way. In its center detent position, this special balance control is completely out of the circuit. Also to be able to execute some sonic authority over what is handed to you in a given recording or to just make your headphones sound nicer (to you!) we have provided historically proven pleasing and gentle Tone Controls - and these Baxandall Bass and Treble equalizers can be completely bypassed at the push of a button. Try them! We think you really will enjoy having the choice to enliven and enrich your sonic experience.\u003c\/p\u003e\n\u003cp\u003eAlong those lines, the Variable Feedback control allows you to control the amount of overall negative feedback applied to the amplifier from 0dB, or no Global Negative Feedback, to 10dB of NFB. Negative Feedback in electronics is when a small portion of the output signal is re-introduced back to the input signal to provide a more stable and beneficial corrective result. This control is very useful when determining how “tight” you want your amplifier to sound. For example, a simple female vocal with minimal percussion can sound more intimate with very little feedback, but a complicated symphony orchestra passage may sound better positioned with more feedback. Applying different amounts of negative feedback can also affect the slew rate and apparent “speed” of the sonic character. Other aspects for which to listen include placement, forward or relaxed, darker vs shimmering, or punchy vs mellow. Feel free to play with this knob and listen for the not-so-subtle diversity that altering the amount of feedback provides. It’s one of our favorite circuit tricks and we’ve been pulling this one for decades!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAh! And our other coolest tonal trick: Switching Topology!\u003c\/strong\u003e\u003cbr\u003eWe’re pretty sure we originated this concept in the audiophile world back with the Manley SE\/PP 300B power amplifiers and it’s only because we have our own in-house magnetics department that we are able to devise such complaisant output transformers that can accommodate such radical demands. The Absolute Headphone amplifier features custom hand-wound air-gapped dual-mode MANLEY IRON® output transformers, designed and manufactured at the Manley Labs factory in California. Interestingly, the output tube stage can be switched on-the-fly between all-triode Push-Pull to Single-Ended topology. This completely alters the harmonic structure from odd-order to even-order and basically halves the output power again providing yet another spicy ingredient to flavor the sound.\u003c\/p\u003e\n\u003cp\u003eAdditionally, with a push of a button, these transformers cycle through three ranges of output loads accommodating headphones from 12 to 600 Ohms or greater. Choose between three sets of outputs: the expected ¼” TRS Headphone Jack, a 4-pin XLR Balanced Stereo Output for your high-end balanced headphones, and a set of stereo RCA outputs to use this component as your line-level preamplifier in your existing hifi system. The Bypass Thru Mode sends RCA Input 1 directly to the RCA Outputs, when in STANDBY mode. Useful, as your main audio system sources can drive either playback system without having to change upstream cabling.\u003c\/p\u003e\n\u003cp\u003eThe Absolute Headphone amplifier incorporates our own innovative purpose-designed-for-audio High Voltage switched-mode power supply. All super-low impedance DC rails are fully regulated and worlds quieter than any linear supply we have ever encountered. The resulting sound is fast and dynamic with a deep punchy bass, deadly-quiet inky blacks, and superior headroom.\u003c\/p\u003e\n\u003cp\u003eThe 6AQ5 or EL90 is the vacuum tube used in the output stage of the Absolute Headphone amplifier. It is well suited for our purposes in a headphone amplifier. The tube is configured as a triode due to the low power requirements needed for headphone use. This tube is widely available from well-known manufacturers such as RCA and GE. The tubes can be ordered as a matched quad and for ease of use the tubes do not require biasing.

The Aurium is a pure class-A amp that couples a tube stage with a MOSFET power stage. MOSFETs sound like tubes yet have a powerful grip on bass. There are few better ways to combine the magic of tubes with the extended and tight low end of solid-state than the Aurium.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eThe zero-feedback circuit offers all of Pathos' hallmarks: exquisite musicality, airy transparency, punchy dynamics, and total lack of listening fatigue.

Inside, there are details that make all the difference. For example, the DC filament transformer is shielded from the rest of the sensitive circuitry, lowering the noise floor.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eOn the back of the Aurium is a balance control to ensure your soundstage is dead center. There is also a gain trim setting which allows listeners to set a comfortable range on the volume knob, thus optimizing Aurium for headphones of any sensitivity. Worried about your low-impedance in-ear monitors? Fear not. The Aurium will handle those and pretty much any headphone available. The stock power supply is beefy and gets the job done with aplomb.

Double that of its multi-award winning transportable brother, Hugo 2 (49,152).

This is a system that enables more natural channel separation and wider soundstage by moving a part of the lower frequency range to the opposite channel. Listening to a regular headphone amplifier places you “in the middle of the orchestra” – with certain instruments being heard strictly in the left ear while others only in the right one. Depending on the type of music, this can cause discomfort and listener fatigue. That`s why we decided to implement user-switchable cross-feed function among selected products. This lets you try a more natural, less clinical–“front-facing orchestra” experience – like in real life.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUnrivaled neutrality and soundstage\u003c\/li\u003e\n\u003cli\u003eIncredibly detailed and dynamic presentation\u003c\/li\u003e\n\u003cli\u003eCrossfeed circuit - a revolutionary solution in tube amplifiers\u003c\/li\u003e\n\u003cli\u003eVirtually no background noise\u003c\/li\u003e\n\u003cli\u003eBeautifully hand-crafted\u003c\/li\u003e\n\u003cli\u003ePremium driver tubes\u003c\/li\u003e\n\u003cli\u003eImproved noise reduction circuit\u003c\/li\u003e\n\u003cli\u003eHigh-end class power transformer\u003c\/li\u003e\n\u003cli\u003eExtended 3-year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBox contents\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBeautifully handcrafted tube amp\u003c\/li\u003e\n\u003cli\u003eMatched pair of driver tubes Psvane CV-181 Mk2 “Gold”\u003c\/li\u003e\n\u003cli\u003eMatched pair of power tubes 6N13S (NOS) \u003c\/li\u003e\n\u003cli\u003eAC cord\u003c\/li\u003e\n\u003cli\u003eUser Manual\u003c\/li\u003e\n\u003cli\u003eWarranty Card\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 100 kOhm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003cstrong\u003ePower Output:\u003c\/strong\u003e 280 mW\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGain:\u003c\/strong\u003e 20 dB\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOptimum Headphone Impedance:\u003c\/strong\u003e 32-600 Ohm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHeadphone Outputs:\u003c\/strong\u003e XLR, 6.3 mm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions (DWH):\u003c\/strong\u003e 12.3\" x 8\" x 7.6\" (31.3 × 20.3 × 19.3 cm)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 15.4 lb\u003c\/p\u003e","brand":"Feliks Audio","offers":[{"title":"Default Title","offer_id":41996902269112,"sku":"FLA-EUF-EVO","price":3349.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/products\/IMG_1758.jpg?v=1741630443"},{"product_id":"feliks-audio-envy-headphone-amplifier-open","title":"Feliks Audio Envy Headphone Amplifier (OPEN)","description":"\u003ch1\u003eFeliks Audio Envy Headphone Amplifier\u003c\/h1\u003e\n\u003cfigure style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003e\n\u003cblockquote\u003e\n\u003cspan\u003e“\u003c\/span\u003eThe Feliks Audio Envy is a future classic already ... you will never need a different tube headphone amp.\u003cspan\u003e”\u003c\/span\u003e\n\u003c\/blockquote\u003e\n\u003cfigcaption class=\"source\"\u003e— LIEVEN, HEADFONIA 'RECOMMENDED BUY' AND 'BEST GEAR'\u003c\/figcaption\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003eClass A single-ended transformer-coupled, balanced amplifier, powered by 300B tubes.
