5:19pmFirst try moving the speaker placement. I would try pulling them out 5 feet into the room just to see how that changes the sound. I am not one for power conditioning so I would take that out all together. The Benchmark is below average DAC, and the Plinius is average. Then play around with different speaker cables to see if you can hear a difference. I would not pay $2000 for room treatment. That's my opinion.
Yes, I've played with speaker placement a bit since originally posting this. Keeping them about 8 feet apart now (max I can do with current furniture, etc) -- stage seems to be a bit wider. Don't know how much more I can pull them out into the room though...
