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

I've been into hi-fi since the early 70's have owned more gear than I like to think about. Don't know if there is such a thing as a keeper for life. My most recent plunge is a Will Vincent upgraded ST-70. Have always owned SS amps, this is my first tube power amp and I must say it sounds night and day from any SS amp I've had to date! I've owned the big ones in SS such as the Rotel 1090 which is a respectable piece. But I must say that this tube gives such depth that no SS I've owned comes close! Is it a keeper for life, don't know, but I do know that I've never owned a SS amp that I considered a keeper for life!

Roxy54, I've always wondered how the 2105 sounded. Have thought about picking one up many times but have not pulled the trigger. Have you ever put it up against a tube amp?

Currently own four different power amps, modified versions of the adcom 555II, hafler dh220, rotel 951mkII, and Will Vincent st-70. Have owned several carver amps, a mac integrated, auditioned a mc2200 and bryston 3b in my current system. When it comes to vocal reproduction and soundstage nothing to date beats the st-70 in my system. The moded 951mkII comes in second, nice soundstage with the vocals a notch or two behind the st-70. The moded 555II is a power house no doubt but is very two dimensional and weak in the vocals. Much to my amazement the mac 2200 and bryston 3b were the worst both brittle in the top end and flat in the bass! Before the mods the little 951mkII was not listenable imho, replaced the filter caps with nichicon ones and all circuit board caps with elna silmic II's. Big difference, stock caps were terrible. I'll keep the st-70 and 951MkII for some time but can't say the same for the others.
