NUPRIME EVOLUTION ONE-BEST CLASS D AMP ON THE MARKET


I'm not salesman, just a senior audiophile and I have decided in recent months that I'll never go back to conventional AB
amps since its prehistoric technology going back 50 tears. The subject here is currently the worlds finest Class D amp in its price range and beyond, right behind Patrik Bostroms' massive Class D Marten M amplifier. I wouldn't waste my time with Brunos' Mola Mola Kaluga, since the Nuprime technology is newer and has moved further on. The Evolution One has technology that is a first in the industry. Ten years ago, the real problem with Class D amps and today as well, is that their transistor switching modulators operate at a frequency around 300khz which is to low causing feed back problems to the upper frequency's resulting in cold hard sound from the tweeter. Brunos' Kaluga switches at 500khz which is still not good enough, resulting in the Evoultion One being the only Class D amp in the world to switch modulate at 700khz. Also, the only Class D amp on the market with an input impedance of 1 million ohms. Phew! So the issue of working with different Preamps is redundant and completely irrelevant and will work perfectly with any Preamp on the market, tube or solid state. Their switching amps are custom designed in house and are patented. For those concerned about speaker 2 ohm impedance loads read the recent review in Totally Wired where the Monitor Audio Studio's were used and are 2 ohm loads and the amps ran cool. Also, legendary circuit engineer Demian Martin from Spectral has been an ongoing consultant for the company.

tjassoc..the Merrill Veritas amps are pricey and I have no idea who the engineering team is behind those amps. But with Demiam Martin involved
with the Evolution Ones, is why I'm purchasing the amps in the near future and us older guys are well aware that Spectral Audio was the Rolls Royce of high end back in the late 80's. Demian Martin is way above Nelson Pass as a design engineer. Read the Totally Wired review of the Evolution Ones to get a full insight of remarkable these amps are.
To keep some perspective you should understand that Totally Wired just happens to be a NuPrime dealer and is historically a huge fan.
bill_k...good point which is quite common with reviewers who also happen to be dealers. The link at the bottom of the review has other reviews that are very positive as well. The board layout of the Evolution One is very well done, well organized in the different stages and very clean. Typical of Demian Martin.
