Hi Anthony I would just like to point out that I think your build quality is far superior to the Classe Audio, I've been doing some A/B testing of the 2 x Classe CA-M400( http://www.e-hifi.com.au/classe/Amplifiers/cam400.aspx ) and the nxV500's.I think the nxV500 are better, the M400's are $10.9k each!You have made some fine amplifiers :) Nicholas HCanberra, ACT

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
