Class D is just Dandy!

I thought it was time we had a pro- Class D thread. There's plenty of threads about comparisons, or detractors of Class D.

That's fine, you don't have to like Class D amps, and if you don't please go participate on one of those threads.

For those of us who are very happy and excited about having musical, capable amps that we can afford to keep on 24/7 and don't require large spaces to put them in, this thread is for you.

Please share your experiences with class D amps!

HI @jrunr

Yeah, Theta is owned by ATI, btw!!

The Prometheus AFAIK uses custom linear supplies also, which explains the huge size. :)

NCore NC400 is a very simple to use module designed by Putseys for Do It Yourself implementations.


As far as I know, the Theta Prometheus module is a full NCore NC1200 module, not a low end NC400. Hypex NC1200 cannot be purchased by individual audio enthusiasts for DIY projects. It can be sourced only by qualified high end audio manufacturers, such as Theta, Merrill Audio, Bel Canto, Rowland, and other similar companies.

One idea I had long ago was to build digital amp modules for the old Theta Dreadnaught line. Theta has already introduced a D version of the Dreadnaught though, here:

@guidocorona

is correct about the module used in the Prometheus.

http://www.stereophile.com/content/theta-digital-prometheus-monoblock-power-amplifier#1uPJbsjlSAtFgo...

I wasn't paying attention to the specific module, just that it was a Hypex nCore. But they DO use the NC1200.

All ff the nCore modules are easy to use, by the way, but you are correct, only the nc400 is available at retail volumes.

Best,

E

@guidocorona,

I believe Bel Canto's REF600M is based on Hypex’s NC500 OEM module and SMPS1200 power supply.  They do not use the NC1200 Hypex module.  

I am hoping to try the 600's in next couple of weeks. It would be interesting to see how these mono's stack against the ATI's 544NC which is using the same NC500 module in bridge mode per channel.
