Amplifiers:A Keeper for Life. Do you know of one ?

Aleph 30 is a great amp. I was bummed that it had too high a damping factor for my speaks.

try a mc cormack or plinius for solid state or a vac for tube

I'm not giving up my Spectral DMA50 any time soon, and I'm always on the look out for another as spare or for bridging.
I've had a Luxman M12 since new, and it's not going anywhere either. I just got a pair of B12s (mono versions of the 12), and if they prove as musical & reliable, then I'll have another "amp life partner".

I aquired a Luxman M-4000 recently and although I only have about 40-50 hours of listening on it, I am smitten! I don't think it will ever leave my house. And frankly I don't ever want to carry it upstairs again either.

When you get tired of switching amps every few years (months), whichever one you have may be a keeper for life - if you are old enough.
