Hi Anthony,Thanks for the quick reply.The modules have been tested and sound fantastic playing through my now very quite old Bose 901 speakers.I plan to purchase a valve pre-amp to mate the power amp to.Then my final project will be to build a set of speakers, either Jim Holtz's Statement IIs or Troels Gravesen's Seas Classics, either of which should do justice to this fine amplifier.The testimonials praising your NXV200L dual die amplifier modules are certainly justified.Thanks again and Kind Regards,John from NSW, Australia

So very happy with my NVX200 R2 based amplifier designed with Anthony at HPA. I replaced my Arcam FMJ power amp and the difference is incredible – so much detail was revealed that was previously missing and immediately all those superlatives I had read about top-end systems in magazines like Stereophile made sense. Truly a veil was lifted: attack and decay are massively improved and suddenly instruments such as piano, toms and even drummers hitting the side of the snare and woodblocks are so much, much more realistic. Other highlights for me include huge detail in the fretwork of guitar players sliding from chord to chord and almost too much noise from some vocalist’s mouths – when they are not even singing! I love it!Arguably DIY audio is not for the faint-hearted and it definitely takes a bit of time to realise, but IMHO the results are unquestionably more than...

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...
