used rotel amp

If it is just 3-4 years old now, I'd be surprised if it didn't last more than another 3 to 4, at least under normal usage conditions. Rotel enjoys an excellent reputation for reliability. Cost of repairs would obviously depend upon the problem, but I wouldn't expect exorbitant repair costs, again for a "normal" problem.

Rotel amps are very reliable and well made. If not abused expect a long sevice life.

Someone snagged the Rotel before I could buy it, so I ended up buying a 3 channel acurus A100X3 amp. My fiance liked the looks of this amp a lot more even though I told her I would have to buy another 2 channel to complete it. So now I need to get cables. I have the same Klipsch and Denon as listed above. I have tried MIT and liked there sound. The guy I bought the amp from recommended a guy who does custom canare cables in the $40-60 range. I also ran accross the outlaw cables which sell in the $30 range that looked like they were made rather well. I am wanting a warmer cable more like the cardas and less like the kimber pbj. I dont want to go bright or else the horns in the klipsch will go crazy.

I have a 20 year old parasound hca amplifier that still works great 

Heat is what kills electronics. 

I don't think you can go wrong with older quality equipment. 

Replace the main capacitors and enjoy
