Hey,
Im planning to build a 5-7 channel class D amplifier.
Im on a budget, and think the hypex UcD Modules is a bit too expensive. Is there any other good preassembled boards with outputs of 125w+ in 8 ohm that is recommended?

Well, I'm at least interested in the responses you get. I asked a similar question but with way too much detail in the chipamp forum, since I would be interested in either/both of those solutions. At least some of my power requirements are in the same range as yours.
Stuff I've run across while searching which may be worth investigating, at better price points than Hypex:
- connexelectronic.com has a wide variety of amplifier modules pre-assembled, and a variety of SMPS power supplies, and several boards which even have the power supply integrated. Stuff based on IRS2092S at different power levels, as well as other chips. And some class-T and AB stuff too.
- profusionplc.com sells ETAL group Anaview modules directly to the public, a model or two is in your power range, and the boards have integrated power supplies
From everything I can find, the CADaudio.dk stuff may look good on paper but from a buyer beware viewpoint seems best avoided.
Sure electronics and YJ boards from partsexpress, lots of models, prices are good, mixed reviews (mostly not great) here on diyaudio. Don't like all the miniature fans on the Sure boards.

I'm currently working on an 11 channel Atmos amp using Icepower 50ASX2BTL boards. Many of the options described above were considered - what I'm doing now looks like it will come in at $125 per channel for everything. The 3251 options look promising but I wanted to get going.
