THE BLACK BY BEL CANTO- NEW REFERENCE

The new Bel Canto mono blocks that just came out, called BLACK BY BEL CANTO, weighing in each at 45 pounds, may be the amp I mentioned in a thread two years ago that had bee delayed for release back in 2013. The mono amp that John was working on back in 2012 was a Class D amp with no switching module replaced by a very large DC power supply. Reading the info on the website, would conclude this is it. Its also using a Ncore power supply as well. The large main power supply John designed would account for the heavy 45 pounds each. These new mono amps are part of a new three piece system. The amps are $15K each. Go to the Bel Canto home page. Scroll down to the very bottom right and click black face plate option and this will open up the new pages for the Black system. Has anyone out there heard these amps?

Sounds like the cat's meow.

I understand the design motiviation but large expensive Class D amplifiers seem to defeat the primary advantage of Class D amp technology for most, ie lots of drive and muscle in a small, light, reasonable cost package, er, kinda like the current BC CLass D amps.

Seems to me the efficiencies of the switching power supply, is a key to this.

The value might be if this kind of Class D design is able to outperform anything else. Could be. I guess if you really want the biggest and best, you should still expect to have to pay for it.

Audiozen, I see no evidence on the system description page of NCore power supplies.... I see a reference to an NCore power processor, which I interpret to be a power conversion module of some kind...

"The analog signal passes through custom discrete Bel Canto balanced amplifier stages for current conversion and voltage amplification. Each PowerStream Mono Block holds a Bel Canto nCore Discrete Power Processor stage that can supply 1200Watts and 40 Ampere peaks to the loudspeaker with 128 dB of dynamic range."

Admittedly, the above is a bit confusing... I will call up Mr. Stronczer when I have time and will try to get a better description.... Will post it here.

Saluti, G.

I'd like to know what the story is with NAD's new M22 stereo amp. They say it uses NCore technology, but at 250 wpc and $3,000 I don't see how it could be either the NC400 or NC1200 modules. Wonder how it sounds ... ?

Guido..you are correct. The Ncore is a power processor receiving current from Johns' main HSDR power supply.

Drubin, as far as I know, the new NAD may be using a Hypex module derived from NC1200, targeting OEMs for lower power applications. It would be interesting to hear it. G.
