Default 2*100x2 or 4*100x1 ? Which would be the better route?

I would like to park the two amps I am using right now for my bi-amped 2 ways and replace them with something else, for various reasons. Space being one, Those two are a Kenwood Basic M2a and the other a NAD 2100. A bit of overkill for those on 5" woofers and 1" dome tweets, respectively. So on to my question. Whether to go for the Sure 4*100 or two of the 2*100 boards? On the surface it would seem the best way to go would be the 4*100 but, that I'm sure isn't always the case. Not all things like this are created equal. Read a fair bit about mods on the 2*100 but not so much for the 4*100. This may be something I want to do down the road. Quality is another issue. It seems like there are more 2*100 boards out there than 4*100 and that the 2*100 has been, for the most part, sorted out. Is this true for the 4*100 as well? One other question is will the power supply recommended (Meanwell through PE)for the 4*100 work also for two 2*100 boards? PE recommends the same PSU for both. I had considered going with 2 LM3886 chip amps but the cost looks better for the Sure boards and the sound seems to be comparable, depending on who you ask. Any reasons to point me in one direction or another are appreciated.

I have no direct experience with them, but for me it would depend on the setup. I would see it as an advantage for the 2X100 if I could place the amps near each speaker. If the amps were to be in a central location either way, I'd probably go with the 4X100 for simplicity and cost, unless you plan to run all the time wide open, in which case doubling up on the power supply can't be a bad thing.

From what I am gathering here Sure Electronics New Tripath Board 4*100W class-D Amplifier Board The 4x100 boards are better than they first were. But, the last reference to quality there has been a few months ago. Maybe I should post these questions over on that thread. I guess it's hard to find someone that has experience with both boards.
