I listened to his Alexia's the other night, and was mighty impressed with them. They do not seem to cause near the problems as the D3's. I thought the D3's were even a bit ripe downstairs, and it is a much friendlier space than upstairs. I hear some of the magic the D3's are capable of, but the midbass/bass can be problematic from my short listening time with them. I would take the easy road and keep the Alexia's....then enjoy the awesome library you have !!
But if you insist......contact Bob Hoodas. He sets up world class studios/rooms, from what I've heard. Or, contact Nyal Mellor. He is an expert trainer for the DEQX HDP-4 (which you have....correct ??). He can train you via webinar, set your system remotely via computer, or fly-in. He charges $125.00 an hour, and said he could have me operating the DEQX unit within an hour. That is WAY CHEAPER than some of the options you mentioned in this thread. Plus you would gain an immense amount of understanding about your room/system. Maybe I can come up to speed on my DEQX in the next few weeks, and give you a hand (or a bigger mess than you have now). I'll help any way I can. But only one speaker move per day, please......those stairs are a bear !!!!
