Hi Anthony As you probably know, I have an amp based on NxvR200R2s. Subsequently I have bought 4 of the new HPA-nxV200L R3 Signature modules. I have now built-in two of them into the same enclosure as used for the R2s, using the same power supply.I am into the process of burning them in - another two are waiting to replace the amp boards in another amp.I must say that I am very very impressed. They seem to have everything the nxV200R2s have - only even more clarity, without compromising one of the qualities that make the nxV200R2 really stand out - their ability to not sound (too) bright as most solid state amps and deliver the energy in the all-important lower mid range (150-300 Hz?).Last night I found myself rocking to music that I have before barely noticed...You claim that the R3 modules have more power over the R2s. I...

Dear Anthony,I've installed the nxV200 R2 amplifier modules and I have to admit that they sound very well! First thing one notices is that the modules will happily deliver a lot of tight and clean bass. Next thing, is the wide bandwidth. Using a descent source, all the detail will be easily noticeable. Mids are realistic especially if one plays some jazz music, and high frequencies can be really sweet and clear. However, as many others have already mentioned one can easily tell a good quality from a not so good quality recording. Overall, I am very pleased with the modules.Well done!Here goes a pic of my amplifier finished. The amplifier is built in dual mono configuration with a 2*28V, 300VA toroidal transformer, two 35A/200V rectifier bridges, four 6800uF/63V/105C filtering capacitors per channel and 100nF/630V mkp bypass capacitors. I used 4.7uF/450V mundorf coupling capacitors in the input stage although my...

HPA-nxV200 R2 based  dual mono amplifier Configuration: Dual mono (2 x 500 VA), separate supplies for input stage (2 x nx Volt One) and output stage (90.000 uF per channel). The amp was easy to build and worked as expected “out of the box” The nx Volt Ones needed adjustment, but if you give them a proper input voltage, they behave exactly as described. The questions I had during building were promptly answered by Anthony. And had I bought the right secondary trafos right away, I would not have needed his support at all. Listening Impressions To set my personal bias straight: I have been passionate about Hi Fi for + 40 years, I have heard a lot of gear, including top of the line amps from Audio Research, Naim, McIntosh, Classe, PassLabs,  etc– and I am lucky enough to have a pair of very capable speakers (Audiovector SR6AA), so...
