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.

My behavior is only based on your silly perception that the SE-R1 is high end, which it is not. Why aren't you comparing it to other world Class D amps, which you won't is puzzling to me, all you are doing is focusing on the tech side and nothing else assuming their design results in state of the art sound. Have you read the remarkable review on the Totally Wired site? At the end of the review there is a link to many other Pro and Audiophile reviews that all have the same consensus that the Evolution One is the best Class D amp on the market.

     " The Evolution Ones' are giving us the best of sound quality attributed
to Class A or Tubes with fluidity, ease and open nature".....

With a statement like that Ihasaguy..its obvious your not an Audiophile
since you have no clue of the current advancements in Class D technology. I hear you save a lot of Radio Shack coupons and I just heard
their having a 50% off one day sale tomorrow on their " state of the art "
Receivers that would be perfect in your living room. Better get there early so you don't have to stand in line.

The opening statement was sufficient to see a pure shill.
The hyperbole in the opening typically is that of a shill.
👍 You saw it too, all too obvious, how many others saw it? He really needs to go to shilling school.

Just perfect for you sunshine, you really got off on the wrong foot with this attempt at shilling for Nuprime, even tweak1 did a better job with his EVS thread.
If your going to bag something straight off the bat, you better have "some" technical knowledge of what your saying, you had zilch, nada, nothing.

Can't stop laughing at the "shill" comments since you ignore why I focused on Nuprime in the first place. I could give a rat's butt about Nuprime. It has nothing to do with the name or the company whatsoever.
My only interest is Demian Martin. If I found out that Demian was on the design team for the SE-R1, I would be all over that amp like stink on a monkey. As many are aware, Demian is the number circuit designer in the country given his reputation back in the 80's and early 90's for designing the top solid state Class A  Amps and Preamps. Just one on the many innovations that Demian developed, that was a first in the industry, is the circuit board material used in the Spectral amps and Preamps that Spectral has an exclusive, due to their contract with Dupont. That yellow/gold material is polysulphone which is known for having the lowest noise levels against any other circuit board material outside of solid gold.
I have been aware of GaN transistors for five years since at that time I posted a comment on a thread on Gon back then, my comment was, "Whoever comes out with a transistor that has very high heat resistance is when tubes will be a thing of the past ", then further searching on the web I came across a GaN article. If I'm not mistaken, I believe the GaN transistors were developed around 2013. The fact that they switch ten times faster then Mosfets is remarkable. Just because Technics implements the GaN in the SE-R1 doesn't mean the automatic result is
world class state of the art sound. I have spent some time on YouTube listening to the piece and the R-1 through my Altec Lansing processor and my Koss Pro AA  headphones, and came to the same conclusion as the Audiophile's on Audioshark who listened to the amps at the shows. The amp sound is on the colored side, warm, relaxed but does not have the dynamics of the best solid state Class A amps on the market. If one is not concerned about weight or whether an amp is Class D or A/AB and your going to invest a whopping $17K, You would be better off buying a Spectral, Luxman, or Accuphase amplifier that would blow the SE-R1 right out the window.
