The Envy Susvara Edition sits above the Envy Performance, and its many upgrades bring it very close to the level of the Envy 25th Anniversary Edition.\u003c\/p\u003e\n\u003ch4\u003eIncreased Power Output\u003c\/h4\u003e\n\u003cp\u003eThe most important change is the increase in power output to ably handle the Susvara's lightning-fast demands. The Susvara Edition sports new gain settings:  Low, High, and Susvara. The latter provides up to a 12% increase in power output. The Susvara Edition outputs up to 9 watts of power, a significant step-up compared to the Envy Performance. Thanks to that, the Susvara Edition can power any headphones on the market, harnessing every ounce of your headphones’ potential.\u003c\/p\u003e\n\u003cp\u003eAnother improvement is the use of new amorphous-core output transformers. The Envy 25th Anniversary Edition taught Feliks how much difference this type of transformer can make, so using\u003cspan style=\"font-size: 0.875rem;\"\u003e it in the most powerful Envy edition to date was obvious. These custom-made components provide ultra-low noise and superior dynamics compared to other amplifiers in the summit-fi class. Another advantage of amorphous-core transformers is the incredible extension of the frequency response, absolutely essential in an endgame headphone amplifier.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eThe Finest Tubes\u003c\/span\u003e\u003c\/h4\u003e\n\u003cp\u003eThe Envy Susvara Edition comes with some of the finest 300B tubes available: the Stradi S300B. This carefully matched premium 300B tube set provides great frequency response and a precise, detailed, and airy sound signature. This arrangement results in the most technical and detailed presentation achievable with your favorite headphones. Envy Susvara Edition is compatible with any 300B power tubes that have a standard filament voltage of 5 Volts, allowing you to tailor the amplifier’s sound to your specific needs.\u003c\/p\u003e\n\u003cp\u003eApart from the power tubes and transformers, several signal-critical components, such as capacitors and resistors, have been upgraded, matching the Envy 25th Anniversary Edition. Using high-precision components from brands such as Jantzen, Vishay, Nichicon, or Dale, Feliks is able to maximize signal clarity and fidelity. A number of modifications to signal wiring have resulted in better noise reduction.\u003c\/p\u003e\n\u003cp\u003eAdditional improvements include tweaks to better stabilize tube parameters and enhance protection in case of tube failure. The preamp output has also been modified and optimized to reduce noise levels and better handle the higher signal levels. \u003c\/p\u003e\n\u003ch4\u003eThe Finish\u003c\/h4\u003e\n\u003cp\u003eThe Envy Susvara Edition has a similar design to the Envy Anniversary Edition, but celebrates the solid wood over using a black piano finish. This luxurious, richly grained finish is available in wenge, but other finish options are available on request.\u003c\/p\u003e\n\u003ch3\u003eIn The Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnvy Susvara Edition Headphone Amplifier\u003c\/li\u003e\n\u003cli\u003e2 x Stradi S300B tubes\u003c\/li\u003e\n\u003cli\u003e2 x PsVane CV-181 Mk. 2 tubes\u003c\/li\u003e\n\u003cli\u003eAC Power 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\u003cb\u003eInputs:\u003c\/b\u003e 2 x unbalanced RCA (IN1, IN2); 1 x balanced XLR (IN3)\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eInput Sensitivity:\u003c\/b\u003e 1 V RMS\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eInput Impedance:\u003c\/b\u003e IN1 and IN2 (RCA): 100 kΩ; IN3 (XLR): 10 kΩ\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePre-Amplifier Outputs:\u003c\/b\u003e 1 x pair RCA; 1 x pair XLR\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMaximum Output Voltage:\u003c\/b\u003e 5 V RMS\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOutput Impedance:\u003c\/b\u003e 600 Ω\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMaximum Output Power:\u003c\/b\u003e 9 W\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAmplifier Output Impedance:\u003c\/b\u003e LO at 32 Ω load: 3.8 Ω; HI at 600 Ω load: 20 Ω; SUSVARA at 600 Ω load: 22 Ω\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHeadphone Outputs:\u003c\/b\u003e 6.3 mm, 4-pin XLR\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePower Consumption:\u003c\/b\u003e 110 VA\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDimensions (WHD):\u003c\/b\u003e 13.78\" x 7.28\" x 13\" (35 x 18.5 x 33 cm)\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWeight:\u003c\/b\u003e 33.29 lb.
