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.

   I purchased my first switching amp, the PS Audio HCA-2 before it was reviewed, while my Ayre V-1 was being upgraded. I was instantly taken by its unique presentation which was noticeably improved after installing Black Gate caps. Between in home auditioning a few other brands I upgraded my homes VAC service. I over built fully shielded uninterrupted audio and video circuits which the switchers responded so well I question any Class D reviewers AC source.  
   The NuForce 9SEs offered a substantial sonic improvement in the quickly evolving Class D. The NuForce Milpitas location was right over Hwy. 17 where I hand delivered the mono's for a minor upgrade. The staff there was very welcoming. I purchased their soon to be released speaker cables which were sonically different than the Cardas Golden Ref I was using 
   Eventually sold the the 9SEs for the Hypex nCore 400 kits which currently provide power to studio monitors. Have come full circle with Bob Carver tubes driving the mains.
   I find it interesting but not at all surprising to hear of any advancements NuPrime will have made. Nice to hear about it, thanks.

George, again....I could care less regarding the topology of the Technics.

Sorry but your the i***t that bought Technics and it’s switching frequency up to begin with, then bagged the Technics out, for it’s weight and circuit topology.

Now your corrected you couldn’t "care less" about it.????? Really?

This smells like a Nuprime shiller
https://forum.audiogon.com/users/audiozen/posts
or someone that doesn’t give a **** what BS they write, and then bristles up when corrected.

Phew! Your a shipwreck..So I pointed out Technics has super high switching thats all. I never said anything about its performance. Since you have no clue what high end is, and your engaged to the SE-R1, could you please let us know the date of the wedding?

mrdecibel..I neglected to ask Demian if the Preamps he designed stopped with the DMC-10 or the DCM-12 ? Different forums I've been to go back and forth that either Keith or Demian designed the DMC-12.

Then why was I correcting your BS, go back and read your own bagging on it again.

your engaged to the SE-R1,
Because so far it’s the only one that’s pushed the new GaN technology to it’s limits, and you saw fit to attack those limits in it’s switching frequency and weight, without knowing what the     you are saying not even one iota.
