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.

It’s the way you look at it sunshine, "if" you can understand, obviously with that little insult you can’t see the forest for the trees, and your comment actually befits you more than me.
"conventional AB
amps since its prehistoric technology going back 50 tears" sic

So, my single ended triode Class A amps, using tubes introduced in 1929 suck because they are prehistoric? Class D was invented in 1955. It has taken this long to make them so they don't sound like crap.
I can’t comment on Evolution but I have nuPrime ST-10 for 2 weeks in my setup  and like it more than Hypex Ncore 500, very musical and smooth. I feel bad bc always considered nuPrime as a MidFi brand.IMO,ST-10 highly recommended if you want to try a good class D amplifier!
It's amazing how many 'opinions' there are from those that don't actually own these amps.  I have a pair of Nuprime Ref One's (used to own Merrill Veritas) and they are fantastic.  There is a natural tonality to them, along with super low noise floor and wide bandwidth- driving direct from a fully balanced Mola Mola Tambaqui dac.  That being said, I embrace other topologies as well- still love my modded BAT VK-150SE tube monos, and also a custom-designed 211 SET.  I have yet to hear the Merrill Element 116's, but am curious...
