My main amp is tubed Conrad-johnson Premier 11a, but I have an Adcom 555II I used before C-J. I use it as a backup, I have had it 20 years & NO TROUBLE. Nelson Pass does good work! I love my C-J, but the 555II Is an excellent alternative. IMHO Amps are important, but PreAmps really set the tone. My preamp is an Audible Illusion L3B (brand new, but there are several used on the market)
