Typical lifespan for a 5 channel power amp?

With multi channel HT amplifiers the technology becomes obsolete before the operational lifespan. 

Thank you for all the great advice folks! I always appreciate and value the time and opinions of those of you here that take the time to respond and help...You have definitely boosted my confidence level and I am leaning heavily towards keeping and just enjoying (continuing to enjoy) this magnificent unit. Back in the day it was my "dream" piece when it first came out but I could not afford it. So I ended up going with Rotel RMB1095, @ghdprentice :)...I LOVED that amp and only sold it because of my divorce. But getting this unit was a dream come true, especially for the price. Honestly I almost felt guilty especially when I saw it. But again I was willing to drive (4+ hours) and offered cash in hand so he relented after trying to negotiate a bit but I wouldn't go above the 3K...

Much as I would have hated to sell the Simaudio (interestingly Dynaudio actually recommends Simaudio gear as an excellent match with their speakers-and I currently have Dynaudio Evoke speakers), it is getting up there in age and I was a bit concerned that maybe best to make a move before it's life cycle comes to an end and I really had no idea of the typical lifespan. I will say that in the 1 year + I have had it it barely gets even lukewarm even after running all day long. There was only 1 occasion where it was actually a bit on the hot side to the touch but that was after running all day in 5 channel stereo mode at pretty loud levels...

Once again thank you all for taking the time to respond :)

Honestly, that amp will likely outlast you. The only parts that have a shelf life are the caps, and they will typically last 30 years or more (the dielectric can dry out). I stress "or more" because that 30 year figure is just an estimate. Cool running, overbuilt amps like the Titan will likely last much longer then 30 years before there is any noticeable degradation in sound quality. Enjoy it! The caps can also be replaced at a fraction of the cost of a new amp. My W3 is around 20 y/o and still going strong. Dead quiet, no hums whatsoever, and used daily. Congrats on the deal, that is a heck of a HT amp. I also use Dynaudio speakers.

I’ve had my RMB1095 since 2005. always loved it for HT, not so much for 2 channel music....it's still going great

I actually reached out to Simaudio and they replied right away. They said since this unit came out in 2001, every single one of them is still "active". They only see about 1 a year for servicing (and he said it's usually because someone shorted a binding post or defective startup). He recommended if I have an opportunity to be without the amp for a few weeks I send it to them for cleaning and calibration...WHAT??? I can't go without this thing for 1 day, LOL!!!

@perkadinI  Thank you for the kind words and info...What Danes do you have? 20+ years ago when I started out in this hobby I went through all the usual's (DefTech/Paradigm/PSB/B&W) and someone recommended Dynaudio. Literally the minute I listened to the Audience 82's it was game over. I remember thinking I didn't even know speakers/sound could get this good. I still miss my Audience speaks, but the Evokes have filled that hole more than adequately :)...

 @jl35 I honestly LOVED the 1095 more for music than HT actually, lol...There was something just pure magical about the Dynaudio/Rotel combo for me back then. I loved that amp!
