Where are the commercial class D multichannel amps?fordable modules?

Kjeldsen, you win! Although, you still need power supply, and optionally case, etc. Also, the Behringer would come with a warranty and is already assembled (necessary for a klutz like me.)

But tou are right too. You can get a very good sounding Panasonic SA-XR50 og 55 with Texas Instruments purepath chips for 100-150$ used. I have had a SA-XR50 and it did sound very good on the spdif input (analog was not that good sounding), but my connex 8950modules are much better overall with a 300 watt toroid. This is 2 channel including power supply for <100$ (a DIY'er always have some stuff in the drawer).

Well I am now a Behringer fan (or class D in general). Even if it is cheap junk as many claim, it is damned impressive how much power from just 4 MOSFETS, and the power supply appears to not have any transformer at all. Weird. Depending on what my collection of old amps (I am a past fan of the Carver M400 series). These sell for anywhere from $200-300 on Ebay. Depending on what one of mine sells for, I am going to snatch the one from the girlfriend and replace it with a Behringer NU1000DSP...cost around $270 and built-in EQ for the Bose 901 it would power (she doesn't have a Bose EQ unit.) So for the present, my DIY activity will be limited to removing the fans from iNukes I guess.

I think you should use some of these

Tak! I will consider an easy heatsink. I would have doubts about the conductivity of the adhesive but worth a try at the low price.

I have had a 2x400 watt 4 ohm class d from cadaudio. The heatsink was integrated in the PCB, and hence not visible. I don't no if that's a fact also with Behringer. In that case I don't think extra heatsink is necessary for normal hifi use.

You can see onboard heatsink here

Hi
Have you assembled it? How does it sound?
I'm thinking of getting one. Just ordered a Muse M20, but multi-channel will be useful too. Especially for the price Hence no need in few 2020's for multiway speaker..
I found a SMPS named HAITAIK in local store, looks similary to MeanWell. Shame that they have only 12v and max 350W models, hope I could order through them.
Also probably it's good to discuss this board here: http://www.diyaudio.com/forums/class-d/193903-7-1-5-1-tk2050-8-channel-amplifier-board.html
