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...

Hi Anthony.Thank you for the privilege of building your NV200 R2 Signature kit. I spent 5 days learning new engineering skills, crimping skills and soldering.I have been a dedicated DIY valve amp fanatic for more than 50 years and dabbled with a few decent quality solid state amps in that time and had always been disappointed by the clear but harsh sound. My latest ‘home build’ valve amp is/was an ‘Output Transformer-less’ Transcendental Sound ‘Son of Beast’ running 12 valves including 8 largish EL509s.The sound is breathtaking and airy with a sound cross between solid state and valve and the transparency is spectacular.I had a sudden urge to build another amp. Not a valve amp, because I couldn’t see any way of improving my S.O.B system.After a week of research I came upon Holton Precision Audio which was in Tasmania. How could this be possible?The reviews for Anthony’s equipment were...

Here is a Video Slide Show with Music from Pedro of Belgium. He has done a magnificent job building his 6 channel power amplifier using HPA-NXV203PS 3 channel amplifier modules. Check it Out!
