Looks impressive but I don't see an MC stage; is there one?

As this is probably not a phono but a headphone amp :)

Otoh there are a few interesting bits and pieces at the web site - looks like a lot of high quality pcbs to make your own Krell, Accuphase etc. Would make good contibution to the IP thread :)

Evilspirit, please explain in english what exactly do you offer. You may be surprised at the number of non-pc-correct forum members that will be interested. Me for starters.

Hi sa, Nick,

You're correct. It's a headphone amp which is designed to drive high impedance headphones such as Sennheser HD-600 and so on. And, at facts it is optimized to drive Sennheser HD-600 ;)

When the bandwidth limit circuits (such as input low pass filter)were bypassed, this headphone amp has up to around 18MHz -3dB bandwidth!

Each stage of the headphone amp is designed to working at class A status.

Another especially design is DC Sevro circuit. It's a patented small feed-back loop dc sevro circuit. More stabilization, higher performance, lower negative affect to the amplifier circuit. :cool:
