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

It depends on how long you intend to live I guess.

I haven't replaced the dartzeel in 5 years. Nothing packs the punch and clarity better

I have kept the same amp and preamp for eight years, and will die before they do. The H2O plus stable mate H2O Fire preamp were designed to grow into better systems. They never quit improving with great add on components. It took 8 years with careful system matching to bring out reproduction music I had never the quality dreamed of. Now, music is my only interest.

a conrad johnson mv 125 is my favorite amp, period.

A QUAD is FOREVER! (Untill manufacture was shifted to China, when it became just another import. Quad, made in Huntingdon UK, closest aproach to the original sound, amplified by the fact that even it's origins were close, just up the road in fact. So, the closest aproach is now as redundant as Quad's workforce!)
My 34/306 will last me out, I've been using it since '86 and it still doesn't `clonk!' when powered up. would I recommend it? Unreservedly YES! It more than rocks, it's a classic. I only wish I'd bought the tuner too with the stand.
