Hello Anthony. I have benchmarked the amps to a couple of expensive amps like Krell KSA-300, Luxman M-600A, Dynamic Precision and some other amps that’s regarded to be in the higher level, and none of them had anything on the nxV500.None of the amps where better in any area, control, bass depth, clarity, separation, airiness. nxV500 is probably one of the best amps in the world.Thank you.Jonas LindholmRoboticsEvomatic ABKarlshamn, Sweden

Dear Mr. Anthony,I'm extremelly satisfied with your amp modules, so I decided to build another, more powerful amp.My friends are surprised with the sound and with Yamaha NS-1000Monitor it sounds simply heavenly. They want to see is there any subwoofer installed behind Yamahas, but...So, I would like to inform you that I'll order new HPA-nxV500 R2 modules from you.Thank you for all support, regards,Boris, Croatia   An UpdateDear Mr. Anthony,Now your amplifier is in nice setup.Source is Sony NAC-HD1E, loudspekers are Yamaha NS-1000 Monitor and please, don't ask for interconnect and speaker cables. All wires are custom made, perhaps I can add some money to improve wires, but at this moment it seems that is not necessary to change them.Now, what to say...?Previous setup was with KEF CS5. Not bad at all, but pure renaissance this amp have with Yamaha NS-1000M.You know what Yamaha made before almost 30 years. Compression...

HPA-nxV500 ModulesThis is super sound. I am so happy…:-), Huge detail. In the whole audio spectrum, tight and controlled bass, The middle range is so forward and clean without any harshness, No harshness in the top end, Super high end sound. Perfect for me. A little about myself I am 39 years old. I have been interested in HIFI since I was 12 -13 Years old. And I have heard so many amplifiers in my time.Thank you very much for good product…Kind regardsTorben, Denmark
