I just wanted to say ,

I flippen love what u have done to the amps ,it’s so beautiful and track after track I hear more then ever before ,it’s delicate and tuneful with such great dynamic range. 

Yes do put up a testimonial as they r a lot better then I would ever think ,superior in every way including power usage .

Thank u so ,so much.
