It appears that you can use these as traditional power amps via their analog inputs, but the real performance happens when you use them with the fiber optic link from the Asynchronous Stream Controller. So this is really a different kind of beast for BC.
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?
