processor that could serve as a good preamp

HI everybody
I wonder after how many years does processor start having troubles, like lost of channel, stop working, etc.

What's your personnal experience: which processor and after how many years did they start giving you trouble, if any?
Or maybe you have your processor since many years and they have been flawlessly since then.

It could give me a guidelide about which used processor to look for.
should I look, or stay away from Classe ssp-60, moon attraction 7.1, krell hts...

I don't really need hdmi, I can still connect my dvd's hdmi to the tv set.
My Oppo dvd player does have an HDMI output, and my tv set too.
Right now, finance does not permit high price processor with HDMI and I don,t want to go back to low end component for the sake of HDMI input-output. I suppose I will eventually, maybe in a few years, buy a blue-ray player. Wharn this happen finance will permit to buy whatever processor I wish, brand new ( no more car payment or mortgage.
Application:
Watching lcd tv ( not a 1080) and dvd,
listening to cd ( sometime) and vinyl.

I don't need a phono preamp, I already have a lehmann phono preamp.
It's ok if there's also a tuner, but I don't really care if it's there or not.

Other components:

simaudio amp
B&K reference 20 preamp (defective, no surround, only stereo. This is the one that would be replace. So it must be an upgrade, not a side step).
Oracle delphi 4 turntable, claraudio cartridge.
oppo dvd player (also used as a cd player).
Martin logan Vantage loudspeaker.

I'm interested in any suggestion that you can provide.
Thank you
Dan
