I use this amp Expelec "80W" Carrefour bought for 60 euros in proceeds from the t dmonstration 2004. I knew really nothing the era and I followed the advice of a friend. Quite large but shallow, heavy, parraissait correct.
And the price unbeatable silent ... !

Feedback, after one or two FTEs, he dropped me a FIRST TIME. SAV has left for a fte and relche. A new Service, another Carrefour, and this time he is good, obviously this time they put a solid fuse! He continues to make noise and heat of old times when it is used a lot.
I have not really been able to test it on big speakers but should not be super!

I do not have that choice really would do so again c'tait, ct Boost brand is!
