How Old is Old when considering an Amp? Krell, Bry


Greetings folks. I posted earlier in the week about wanting upgrading my system with a more musical and powerful amp. Heard a Krell system a few years back and really dug it!!! Came accross this KSA 150 and thought it looked inticing. It is my understanding that this unit could have been manufactured from 91-94 ish? How old is this in Class A Amp. years? Is there a point where all good amps must reasonably perish?

Also am curious about any used amp in the 1.5 - 2k range. How's Classe CA 200, Bryston, Plinius? Don't know much about high-end yet but am anxious to learn.

current system:
power plant: PS Audio PS-600
pre-amp: Audio Research LS3
cd: Naim CD5i
amp: Rotel RB 981 {120 wpc} weakest link!
speakers: Paradigm Studio 100's V3.
speaker cables: Transparent "The Wave"
interconnects: Interlink "The Link" 200

I can vouch for Classe's service. I have a CA-200 that had a little problem. I sent it to Classe where they fixed it, made some updates, and replaced the RCA jacks because they showed signs of normal wear. They didn't charge me anything but I did have to pay for shipping. I think I made out considering I'm not the original owner and the amp was out of warranty. Plus, it came back sounding more glorious than ever!

I'll never buy a component who's company offers little or no customer service. It's simply not worth it, especially if you're buying used.
i have a p300 accuphase that is 35 years old and has never been serviced. it performs flawlessly. it is possible for a quality ss amp to go for decades without service.
Electronic equipment can always be restored to original condition, IF, (a big if) the needed parts are still available. The technology moves fast, and the available "new and better" devices may not be suitable for the original circuits. Custom switches and pots are the bigest headache.
Class A amps should probably be serviced every 15-20 years depending upon use. AB amps aren't as stressed and can probably go 20-30 years without any noticeable impact. Since the Krell is near that 15 year mark you should keep that in mind when negotiating a price. Once it's serviced it will probably be good for another 15 years. I'd imagine with proper maintainance an amp could last forever.
