so I got the XMC-1 today and was able to hook up the LG10k. Of course I don't have much set up done yet or tuned in but what I can say is the set up has really low noise floor. Even with the LG at 35dB gain (I didn't even try other settings yet) the noise coming out of the 212's can be barely heard even when you ear is right up to the speaker! I think it was totally worth setting the dedicated power line for the amp. I am guessing on that gain setting reference is at about -20dB on the MV. Should be a fun weekend, in about 6hrs of REW work I think I will have it dialed in.
