I replaced my krell krc-hr with an audio-gd master1 when the krell volume control motor went nuts and

it took several weeks and about $500 to get the parts to fix it. After fixing it the krell was permanently

retired because the master1 blows it away in across the board. Yes its a big and heavy monster, I leave

it on all the time and it gets fairly hot. The krell fpb600 has since been replaced by a pair of master2

power amps. The pile of retired krell now in the basement exceeds $50k.



I have the schematics on all the audio-gd stuff, and it mirrors my current design thoughts on a lot

of what I have been thinking about lately. But lets face it, I cannot even buy the parts or raw material

to build this stuff for the prices kingwa is selling this gear for. Really high quality for a goofy low price.



although I have not heard it, knowing the design concepts of the master8 I expect it to sound outstanding

regardless of price.



I have not heard the bakoon amp either.



but all this stuff is current conveyor based, as is the ayre stuff and some of the other new high end stuff.

its the only way to do ultra low distortion designs with no global feedback.



I may still buy the d'agostino preamp and a pair of his power amps next year. They get very high ratings.

Maybe I have not learned my lesson yet.



The GSX2 is still my favorite medium powered dynamic headphone amp. By a fair amount.

My supersymmetry balanced dynahi is my favorite high powered dynamic amp for ultra low efficiency headphones like he6.
