Thanks @Hal. You are still using those Parasound A23s in your line arrays, correct? That might be another amp to consider for powering the coaxial drivers. There is likely some reason that you picked that A23. I think you have about 10 now, right?
Anyways I received the little 22 watt AudioEngine amp to try out yesterday. For the price, it's pretty nice. Stereo line out, smooth volume control and digital in (S/PDIF, optical and USB), plus a stereo line in and headphone out. Pretty slick. Anyways, its safe to say that the Vs like a bit more power for sure.
Also for whatever reason this amp lets the 12" dig down a little bit deeper, so I am getting a much better blend with the subwoofers.
Should also be getting a chance to try out a Mivera in my system in the next few weeks, so we will see how that does. I have been looking at Dacs the weekend and now am considering the PS Audio Steller Gain Cell Dac. Assuming I can output both the RCAs and balanced XLRs at the same time, that might be great for my system. I could run balanced to either a A23 or AS1200 and then run the RCAs to the A370 sub amps.
BTW, I ended up toeing the speakers to 15 degrees again, as I like the soundstage better, plus I think the toe lets the rear wave be absorbed a bit into the corner bass traps, which ends up sounds a little bit better in the space.
So on the plan would be to get a DAC, figure out what amp I want, and get some floorstanding bass traps to go behind my listening chair at least. Eventually, I'll also want to add some first reflection panels and another soffit bass trap behind me. Thanks everyone for the thoughts and help.
Plus look, I am finally getting a proper cross over between the subs and the co-axial drivers. Nicely summed through the XO region.
