What are you hoping to gain? $35k is a lot of money, even to those that don’t have a hard time pissing it away. Not a fan of DSP for a two channel set up - home theatre, sure. I’d suggest, because I suspect you’ll get a lot out of it is buy Paul McGowan’s new book and associated SACD, The Audiophile’s Guide, The Loudspeaker before your drop that kind of money. The book will not land your speakers in the exact placement but I bet it will get you a lot closer than where you are now. Next, and only after you get the placement and location of your equipment right, then maybe some room treatment if your room allows. There’s many great companies that have nice looking stuff such as Vicoustic and GIK Acoustics. You go through these steps, $58 for the book/disc and maybe $2k in sound treatment then if you’re satisfied maybe get a pair of REL Subs and see how that goes. Depending on your room size, maybe two REL S8/12’s $6k for the pair. Probably improve what you have, a killer system for an additional $8,058 and keep the rest in the bank.
