While I'm not quite ready to pull the trigger on a new amp I am starting my ritual of vigorously researching some different aspects of amp design so I can make a decision. I want a signifcant step up more towards some of the higher end simple designs.
I've long been a Pass-o-phile in the sense that I truely think Nelson Pass and his approach to audio reproduction and his willingless to be available and share his knowledge and designs with no strings attacthed is fantastic. His total approach is KISS (keep it simple stupid). He and I both believe the complexity of most designs today ruin the purity of a musical signal and his approach with zero feedback and simple 2 stage amplifiers sounds extremely interesting.

I also like the simplicity and execution of Monarchy products. Very high dollar to value ratio. While not as renowned as NP and his designs C.C. Poon has made several leaps forward in making extrememly musical products at affordable cost through much trial and error over the past 20 years.
Did you make it this far? Now comes my frustration, I have SDA 1C's and it's no small feat to modify my terminal cup to accept a homemade AI-1 cable which I don't feel like making either. Most of these higher end simple configuration amps are not common ground and can not be used with SDA's. In most instances they are balanced single ended Class A and don't use a common negative ground at the speaker outputs.
Still doing my research but it is frustrating because I really love the 1C's and I know with better components they will finally reach their full potential.
I'm just ranting so thanks for letting me vent
