very nice lanchile! hmm, worth looking into further. the key is fatiguing you mentioned is not there with this amp.

I have a Pioneer AVR with the ICE amps, don't care for the sound these digital amps produce.

Yeah,That is the key!!! I can listen to it all day and still want some more.
I had so many good commercial amps including Bryston B60 and Bryston 4B But this amp kicked their butts big time! I am not joking.

This is a superb amp that uses an interesting topology

GB150

It's big selling point is its exceptional PSRR meaning that the quality of the supply impacts the sound much less than usual.

I've built a couple. The use IRFP540/9240 mosfets doubled up (i.e. 4 total) at the output, all other transistors are BC550/560 series. Power is rated at 150W into 8 ohms, not sure about 4 ohms, but feel free to send Greg an email.

Well, as you saw my amp, it is a simple power supply using some smooth caps on bottom of each mur860 (bridge rectifier board from Audiosector). These amp kits are tested and biased by Anthony before they leave.You do not need to adjust nothing just plug and play!!!. I will post some pictures of these high quality boards.
