I thought I'd give the SqueezeCenter (v7) a try even tho it's still in beta. Install went smooth and, while I didn't time it, the full rescan seems much faster. The new default UI is also a nice improvement but not dramatically so.
But, what I didn't expect... I swear the sound quality is better... more relaxed, less edgy. I'm just using a near-stock SB3 (a Black Sand cryo treated SB3 with a linear PS) with digital out to my Tact. Of course, the sonic improvements may be just wishful thinking on my part, but I'm not about to switch back to v6.5 to find out. Anyone else go down this path yet?
