After about 6 months of frequent upgrading I have been settled with the HD 650/Bifrost/Valhalla for about a year now. I really enjoy my setup, but I'm starting to get that urge to upgrade again. The problem is I don't really know where to start, as I think the HD 650/Bifrost/Valhalla really provide a lot of bang for the buck. I think I have plateaued so to speak with this setup and any significant sonic improvements would require a hefty investment.
What do you guys think? Is there a logical upgrade I could make to my setup? I don't think the LCD-2 would provide that much of an upgrade from the HD 650, and I think I would miss the more expansive soundstage on the 650. I really enjoy the HD 800's soundstage and detail, but I know it doesn't sound like the HD 650 and so I have reservations about long-term enjoyment.
I don't think upgrading the DAC would result in any significant gains, but maybe the amp?
