Hey, I noticed that you are using a MOTU 24IO for an audio interface. I have the same monitors as you do, and I you may want to consider upgrading your D/A conversion as soon as possible. With the amount of outboard you are using, it would be a worthy investment.
I had the 24IO for a while and upgraded to the 2408 mk3. It was a noticeable improvement at the time, but then I upgraded to Apogee converters and it made a massive difference, especially with the Focals. Your I/O requirements are much greater than mine are, but if you do get the opportunity, you may want to look into getting better D/A and A/D as well. I can tell you from experience, that you won't regret it.
I'm still using the 2408 for the digital inputs and PCI interface right now, but I'm doing all my conversion through the Apogee unit, and its a huge difference.
I'm fixing to ditch the 2408 altogether for an Apogee Symphony System, paired up with the Rosetta 200 and an AD-16X, which should satisfy my conversion needs well into the future and give me a lot more channels coming in. Eventually, I want to ditch the Rosetta for a DA-16X and run it into a Dangerous LT for some analog summing.
Anyway, just a thought for you.
