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.

Back your boats up for a moment. The focus is on Damian. Back in 1992,while coming back on a plane from Chicago from a business trip, I spotted an ad in the Seattle Times classifieds of a brand new in the box 
Special edition Denon CD player, a version that was not available in the U.S., the DENON GL 2560 SE. The unit weighed 38 lbs. and there was an American version that weighed 25 lbs. The unit was being sold by an asian phile who was from China, and he bought the piece in Hong Kong.
The moment I got off the plane I rushed to a pay phone and asked him to hold it. In the late afternoon I went to the bank and took out $800 cash and when I arrived at his home, the gold colored unit with rosewood panels was a looker. This was the first time I experience Damians magic. The unit was hooked to a Spectral DMC-10 preamp and John Curls' monster Parasound HCA-3500 to a pair of Acoustic Research tower speaker's. I took a number of CD's including Jazz at the Pawnshop and the sound was so smooooth and rich it took my breath away. The unit retailed for $1100.00 and paid $600.00. When I got it home and hooked it up to my Carver components, it sounded sterile and that rich full mid-range that I heard at the sellers home was not there. I called the seller up and asked why it sounded so good..he said " its the Spectral ". George, I could absolutely care less of those who have their heads in the GaNges river, my focus is on MUSIC and nothing else. There is no logic that the Technics has the advantage at 119 lbs, especially due to the fact that the Evolution One has Damians' magical circuit work that has made him a living legend. By the way, I still have the Denon in storage, and twenty eight years later it still works.

I don’t know about the "magical circuit" stuff?

But do you have any idea about power supplies and what they are??
You say "there is no logic to the 119lbs"
The logic is, one (Nuprime) has a switch mode supply (smp).
The other Technics has 2 x independent choke regulated Linear power supplies, that’s where the weight comes from.
Technics told me, one (ei-core) is for the digital and input/driver stage, and other (r-core) for the output stage. https://ibb.co/s1jD64z

Zzzzzzzz..George, you got a leak in your boat. The rapids on the GaNges
river can be a little rough this time of year. I could care less if it switches once an hour. ITS' ALL ABOUT THE MUSIC FIRST OVER ANYTHING ELSE. By the way, have you ever heard of Demian Martin, cause you sure don't give him the credit he deserves'. Check out the gold DAC with the 24 kt gold plaque on top with Demians' signature on it in the DAC section on the Nuprime site. Looks like a gem. I just may buy that puppy.

Zzzzzzzz..George

Your the one who said
"There is no logic that the Technics has the advantage at 119 lbs"
Obvious you had no idea why it weighed 119lbs, just explaining to you why. And now after I told you, you say boring "Zzz" because you still don’t understand after me telling you?

All your worried about, that it’s got a gold plaque on the top🤦‍♂️

I could care less if it switches once an hour.
Then why did you bring up switching speed in the first place, quite a few times??

Sorry mate, but your all over the place, especially with the title to this thread

Cheers George
