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.

" regarding my zeal for Belles, that was my last straw effort to stay in the
A/AB camp, but after experiencing my second hernia injury in recent months, and having surgery next week, I can no longer lift the heavy stuff. Wake up and smell the coffee and accept the fact that we are now in the 21st Century and the doors have already opened to NEW AGE AUDIO and this old A/AB technology is collecting dust"

So A A/B  technology is now deemed antiquainted and collecting dust  because you can't lift an amp anymore; nice rationale.

Owned the Nuprime Evos as a toe dip in to the class D world of high end, i sold them very quickly, clean crystalline sound they provide, big pin point sound stage, for sure but not music, you could be convinced they have soul unless you have something better to directly compare them with. As a former owner i would suggest trying many other amps before settling on the Evos. As the saying goes - just my 2 cents...

As an add on, I did later audition the Mola Mola's and quite liked them but not enough to part with the hard earns. I liked the low profile and power consumption on the Evo's, see, i do find genuine positives.

Not just a rationale, common sense. We are finally at the point where the science of Class D technology has finally reached the same level of performance equal to the best Class A/AB amps on the market. No point in going backwards if you can get the exact same results from a 20 lb. Class D amp vs. a hot running, suck that power out of the wall, A/AB amplifier.

Shertzy..just curious if you burned in the Evo's between 500 and 1000 hours which I was informed by Nuprime that's the time needed for the amps to reach their best performance. Also, what Preamp and digital source did you use with the Evo's.
