Anthony, congrats on your amazing progress! I know how hard it is to carve out time for this stuff! I see you are looking for gain from your pre-amp, which makes me wonder if you have been using the passive Placette, as opposed to the active unit, which I understood has +6 dB, not to mention a VERY low, locked output impedance. What I am getting from Romy is that a constant, very low output impedance from the pre-amp is as critical for driving your Milqs properly as the input voltage. Not to steer you toward greater expense, but it would be a shame to put out all the time and effort building a pre-amp only to wind up with a reactive situation, where your channels' crossovers are in constant flux. With all the complexity of the greater circuit here, it would be nice to start with pre-amp output locked down. But perhaps you've already considered this fully with the design you're working on?
Best regards,
