Thats all good gear. Especially the Von Schweikerts. If you are handling volume control through your Computer, I suspect that could be part of your problem. Before dropping too much $$ on more speakers, use the Digital out to a Pre/DAC combo. Theta made one some years back. I cant remember the name exactly, Theta DSPre or PrePrime One or something like that. I can tell you this, I had a Theta DSPro Basic One and for the few hundred it cost it was killer. If it doesnt work out, you should be able to sell it and recovery nearly 100% of the cost.
....or maybe the Benchmark DAC with volume control. I havent heard it but it has gathered some good reviews.
I think you would be best served by getting that volume control out of the digital domain, or at least out of that Computer case and into a separate chassis. At the very least, the AC should be cleaner without a bucket of chips, drives, and fans sucking on one power supply.
Also dont forget room treatments. Most rooms have problems in this very area.
