"I won't go into long drawn out discussions about sonic characteristics of amplifiers. All I can say is that there is no clear audible difference between this $230 unit and my prior $2500 amp+d/a . What is clear is that without a signal this unit is dead quiet as all class D units are. The sound quality is simply excellent and if there were any deficiencies the 802 Diamonds should have made them obvious."

Driving B&W 802Ds with XR55?! Seriously, to me it is like a toyota family sedan shod with 18" pirelli zero tyres. Overkill.
