Embedded Hybrid Headphone Amplifier with Sigma22 PSU

Price : SOLD

Up for sell is my DIY build of reference class headphone amlifier design from Cavalli Audio.

Embedded Hybrid Headphone Amlifier

Most of you would know that this amp is often compared to some of the best headphone amplifiers of the world like Beta22, Zana Deux, Aikido etc.

Comparison with Beta22

Comparison with ZDT- a $3k amp

More impressions here & here

Reason for sale : EHHA rev. A

The build also includes the Amb's Sigma22 power supply unit which is touted as one of the best power supply designs out there.

Other Features :

regulated DC tube heater power supply

Alps rk27 'Blue Velvet' potentiometer

NOS 6GM8 tubes

Neutrik RCA & stereo jacks

Black Aluminium chassis ( 13" x 13" x 4")

Note : Selling it at almost part cost, so I shall not be entertaining lower offers. Those of you who know about this amp know that this is a screaming deal at this price.

I reserve the right to choose the person whom I sell the amplifier, this is not a first come - first serve deal.

This is so tempting and would be perfect for some upgrades I've had on my mind! I've got just enough saved up too. Must resist! Best of luck with the sale, I'm surprised its still around with Achal and Anubhav lurking around the forums :p

Well, you can always buy a DAC whenever you want but this amp won't be seen here again for this price.

You might regret it later when you are ready to buy an amp.This is one of the best amps available for your forthcoming needs.

I am not trying to hussle you into buying this one, just putting facts as they are.

And you are always welcome at my place, so do drop by whenever you can.

That's bull$hit. Even a stock single-ended B22 can easily drive any headphone, those guys probably don't know a thing about headphone power requirements.

And the EHHA is just as powerful if not more.
