I'm a big fan of the mastering engineer Steve Hoffman. He's most noted for his work with the now defunct label DCC although he worked for MCA prior to that and is currently acitve with other projects. I've got quite a few cd's from that label and they all sound great. On occasion you can still find these DCC gold discs in the brick and mortar stores even though everything from this label is out of print. Some of my favorites are:

Jethro Tull - Aqualung (probably the best sounding version you're ever gonna hear).
Jethro Tull - Original Masters (this version includes the complete first side of Thick As A Brick)
Art Pepper - Intensity
Art Pepper - Gettin' Together
Frank Sinatra - '57 In Concert
Metallica - Ride The Lightning
CCR - Willy and the Poor Boys

Audio Fidelity has just released a new series of gold discs engineered by Steve Hoffman. The first three releases are The Faces' A Nod Is As Good As A Wink, Doobie Bros' Minute By Minute and Bad Company's Bad Company complete with original artwork and packaged just like the old DCC releases. The Faces and the Doobies I have on order thru CD Universe (which keeps pushing out 'their' release date) but it's not likely I'm gonna get the Bad Company.

Other notably good sounding things in my collection:

The Columbia Legacy box sets of Miles Davis are really outstanding. All the ones I have sound very good. Those include The Complete In A Silent Way, The Complete *****es Brew, The Complete Jack Johnson and Seven Steps: The Complete Recordings 1963-64.

Some of my favs from Mobile Fidelity Sound Labs:

Pink Floyd - Meddle
Pink Floyd - Atom Heart Mother
Dave Mason - Alone Together
Elton John - Tumbleweed Connection
Jethro Tull - Stand Up
