And while your going to all this trouble, here is a little secret of the trade...Don't forget to buy a 10 pack of little square sink sponges,,,,,,they make great sound absorbers on the walls (and look cool).
There's some chap selling a $50,000 U47 on ebay and spamming this forum that would be perfect for your setup. If you're spending that much on interconnects, no use skimping on the mic, now.
