I used this amp for two years. J'tais trs satisfied with the sound quality. Unfortunately, one of two ways broke down after a few months. APRS three weeks of SAV, the amp came back in great shape ... then the path in question lach new APRS two years. N'tant out of warranty, and Samson France refused to rpar in respect of hidden defects, I put it to the cellar and buy another amp (another brand!) .

So gnral opinion: could be a good product, but is not reliable.
