In the last 3 years I have gone through too many class A and A/B amps (integrated and separates) to mention. I just bought a Luxman L-509Z. I use an Aurender A20 as my digital source. Speakers are Harbeth SHL5s 30th anniversary. Even the phonostage is outstanding, IMHO. You will need a cartridge to match the specs of the 509Z. My Ortofon Cadenza Blue works very well.
I am no longer searching for an amplifier.
