Only recommendation I have actually heard in a system I know, Decware Zen ZMA and I think a ZTPRE preamp.....paired with Tannoy speakers, and Furutech DIY cables. Truly an incredible set up....though a new purchase could be a two year wait for the product to be manufactured. It could however be customized to your preference (wooden case, knobs, upgraded caps, etc.)
I know it's not an integrated, and with the cables is about $11,000....but for me would be an "end game" purchase
