I have the 3e 3255 2 channel and also the 3251 3 channel boards. Was lucky to get them thru eBay not too long ago. Great products and fast shipping/well packaged.

I'm in for a pre amp board please

EAUMT-0260-2-A 2 boards
EDSP-1701-24-A opt2 1 board

I have both, the 3255 2CH amp and the DSP. The DSP is a lot quieter then the MiniDSP boards. I do not like the digital volume control, but this is easy to change (remove) in Sigma Studio. Works very well with the Amp boards.

There is one problem with Bluetooth: It does not have an attachment for an external antenna (uses PCB antenna) so I am not sure how much signal would make it into a shielded box. So far I have not used the BT module yet.
