Developed to drive even the most demanding headphones with up to 8 Watts of power

The amplifier is built on a solid metal chassis and finished with a natural high quality oiled wood. On the front panel present are headphone outputs: balanced in XLR format and unbalanced in 6.3mm format. Other selectors include: touch sensitive stand-by button, volume control knob, impedance selector and audio source selector.

The audio source selectors allows choices of one of the three options: unbalanced RCA source (IN1 or IN2) and balanced XLR (IN3, left and right channels).

The touch sensitive stand-by button has a LED indicator. For a full "power off" of the amplifier please use the physical switch on the rear panel of the amplifier, near the AC connector.

Envy can work as pre-amplifier with a high level of maximum output (up to 10V RMS). On the rear panel there is a pair of RCA pre-amplifier outputs as well as two XLR connectors for balanced pre-amplifier output. Output voltage level is regulated with the volume knob.

Very Pleased

"Great amp. Great service. Thank you!"

Darryl M. (5/5)

Feliks Envy - Outstanding Performance

"This is my first tube amp and I was blown away listening to the Envy with my Meze Elites. The Elites already sounded very good with less powerful amps, however I immediately noticed that the Elite’s performance scaled up significantly with the Envy, with greater clarity, soundstage and bass impact (this was with the stock tubes). After a few weeks I tube rolled and replaced the stock tubes with Western Electric WE300B’s, and my listening enjoyment increased again! I also want to thank Justin and Headamp for the great service they provided!"

What an Amp!

"Got to hear this beauty at the 2024 NYC CanJam and kept going back to its amazing sound and impressive ability to power anything you can plug into it. Appreciate the help from Justin in making this amazing TOTL amp a reality in my setup. Makes my HD800 sound better than ever and still not through the 50 hour recommended burn in time. Can’t wait to pair it with the Susvara’s for my endgame setup. Thank you Headamp!"

Feliks Envy is superb

"The envy is fantastic. I’m coming from a ZMF/AmpsandSound Pendant, which I enjoyed, but the Envy is on another level. Greater detail, impact, 3-D soundstage. With the ZMF Verite and Atriums, I’m hearing them at their absolute best. On Head-Fi, Zach (the Z in ZMF) has even endorsed the Envy as one of the very best amps he’s ever heard."
