OK, so I'm currently testing out "Subdivisions" on CD ("Rush Remasters"), my original Apple Library format (256k) and the new Apple Lossless. I can't tell a FUCKIN difference between the three. For settings, I rotated through stereo, Dolby Surround and Multi-stereo and stereo sounds the best to me. The multistereo sounds too obviously fake but is way more "powerful" and good for when you want to be as loud as possible and the DS actually sounds pretty nice but also fake.
I'll try a few different bands....
