hey I opened an account to respond to this, my first post here...
I brought a Cyrus 7 second hand amp in 2003 while living in England, and a Cyrus DVD second hand as well.
Also got a second hand FM tuner 7.5 and run them daily
In about 20 years of hard use my only problem has been one of the inputs is now crackly, no problem, just moved those cables to another input
Sound is amazing, running through some Celestion A1's that I also brought around 2003 and took back to Australia with me.
Maybe I have been lucky, judging by the other comments in this thread. But I have been so happy with it, I have had some pretty good surround systems during this time, high end Denon's and Yamaha's but normally just switch it over to the Cyrus/Celestion combo which has no problem shaking the room if needed.
