Measurements are not good on this amp. Under 8 Ohms, and +/- 48VDC, too many distorsions comes when reaching 60 / 70 watts RMS. The Amp can deliver up to 170 watts but the distorsion is so important at this time that it seems a joke. Without signal, amp is sending some power at switching frequency (not audible) to the speakers ! (The final filter is not enought capable ! Poor tweeters...)
All good. Thanks.
