Actually as of this morning I own four of them, except they are in Asia somewhere and must be shipped to me before I can take custody.

I have a stereo one, but I let someone borrow it. It measured and performed well enough for the price point, there are better TPA3255 boards out there but at a higher cost.

I have both the new and old 3e Audio amp boards and the new one is a clear step up in every way. My only complaint about thenew amp with PFFB is that the gain is a bit low.

Hi, I would like to order a couple of 260-2-29A from http://www.3e-audio.com/amplifier-kits/tpa32xx-with-pffb/, could you please recommend a case and power supply I could put together easily to maximize the amp performance?.

many people use meanwell LRS series like LRS350-48, it is cheaper for a common SMPS.

for some better option and size compact, I suggest one China brand - Mornsun,almost can say it is China Meanwell SMPS vendor.
LOF350-20B48-C also can be find in our aliexpress store.

Can I disassemble the board? I'd like to use the punch to check the screw holes.

@sokool0 all holes are 3.0mm.
