Regarding SQ, I think my favorite is Hall & Oats "Abandoned Luncheonette". One hell of a record!
Old School MFSL
For fans of the older Mobile Fidelity stuff: http://www.elusivedisc.com/MFSL-Sealed-Vinyl-Rare-Out-Of-Print/products/3121/1/0 One of my favorite labels, back in the 80's. I've been a happy customer of Elusive Disc, for over a decade(no other connection).
