Hi there Anthony!..well, the modules (Nxv200) are simply astonishing!the expected control and resolution on the whole bass region(sub bass to mid bass) is amazing , especially considered that I use the"old"psu from my NAD C325B (one toroid, say 230 W ,one integrated rectifier,two (unknown) 15000 electrolitics) for both the two modules.even the rest of the spectrum reveals far better resolution,one of the amazing thinks that I hear is the "life like" sound of metal clash(in movies effects for example, or cymbals..)however absolutely non fatiguing sound!Very well done Mr Anthony E Holton !!!I'm really a satisfied customer.Massimiliano Colarusso, Italy

Hi Anthony I have been using your amp (nxV200)for over a month now, and have made my decision on its sound quality. It is now my main amplifier and I have sold my Duevel amplifier (I see the new price for these amps is now nearly US $5K)In my system it gives my speakers a bit more control on bass lines. I listen to a lot of female vocals and the treble is just that bit better suited to my hearing. So you have developed a stunning unit in my view. All the best Andy, New Zealand

Hi AnthonyAfter building my new power amp. (HPA-nxV200 modules)The result is an amplifier, which is, afterabout one week of burn in, able to deliver a very wide soundstage, a powerful, controlled and well articulated low frequency range, smooth and liquid mids and very detailed but never fatiguing highs. But much more important, this amp has a very own but yet very natural sound signature. It really shows me something about my source equipment, but remains playing everything in a very musical manner. I think this is an outstanding product. It has its own signature, not trying to copy any other amp, and it plays just tuneful, full-bodied and convincing. I really searched for some drawbacks here, but wasn't able to find any!My reference for comparison are some Rotel integrated amps (RA-935, RA-931mkII) and some Naim Audio power amps (NAP 140 and NAP 160). My speakers are some MM Serie Master...
