How long you use it?

5 years

What is so special that you love the most, least?

Restitution looks to me faithful (to take the conditional saw my experience)
It's solid (bought 5 years ago occas', not an issue to report)
Associated with my old Fisher STE-M66 is warm without being vulgar, cream sound, very nice.
JVC speakers on base, it sounds a bit more vulgar. The amp not catch up the speakers, unfortunately.

Did you tried many other models before buying it?

I once had a small Denon not very powerful next sounded like a potato warm.
I also had a HK system with 5.1, not ideal for music, less faithful, a little colder.
I can not even make the comparison with gear monitoring ultra-precise but perhaps soon.

How would you rate the quality / price?

Bought 100 bullets used, considering the quality of bousin, I think it's not money screwed up.

With experience, you do again this choice? ...

Yes. Very warm for a transistor amp (my speakers play a lot in this notice).
