Right off the top of my head, Pat Metheny's "Imaginary Day", Junior Wells's "Come On In This House", and Porcupine Tree's "in Absentia" all come to mind as outstanding-sounding albums. Pick most any track from them and you're gold...
I know before this thread is over, Stevie Ray's "Texas Weather," Louis Armstrong's, "St. James." Pink Floyd's, "Dark Side" and one or more popular Miles Davis cuts will make this list.
Because of that, my list will be a bit off center, tracks chosen for their unique musical content, long term appeal, that particular tracks ability to convey emotion, and recording quality.
I listed recording quality last, not because it's not important, but because "audiophile" records have zero appeal other than testing. With all that said, here is my list for now, no doubt I will add to it later:
Charlie Haden, "Closeness Duets," is the album, "Ellen David" is the cut and it was released on A&M Horizon in 1976.
Duke Ellington, "Jazz Party," is the album, "Malletoba Spank," is the cut and it was on released on Columbia (CS 2187) in 1959
Kate Bush, "Aerial" is the album, "An Architects Dream," is the cut and it was released on EMI in 2007
Bill Evans, "Waltz for Debby," is the album, "My Foolish Heart." is the cut and it was released on Riverside (RLP-9399) in 1961
Cassandra Wilson, "New Moon Daughter," is the album, "Strange Fruit," is the cut and it was released on Blue Note records in 1995
Dead Can Dance, "Serpents Egg," is the album, "Song of Sophia," is the cut and it was released on 4AD records in 1988
Eels, "Beautiful Freak," is the album, "Susan's House," is the cut and it was released on Dreamworks records in 1996.
Radiohead, "Kid A," is the album, "Everything in it's Right Place," is the cut and it was released on EMI in 2000
This is the track that shows off your stereo and can put a tear in your eye. MCA Records "Buddy Holly-From The Original Master Tapes" is the album, "True Love Ways" is the track. This track is in stereo and will give you a wall of sound that shows what stereo is all about. Why can't all albums sound like this track?
There are of many great ones, however the following CDs/ tracks must be considered:
Tangerine Dream--"Dream Sequence" Virgin Records CDTD 1 1985 (Made in France)
Frankie Goes to Hollywood--"Welcome to the Pleasuredome" Island Records 7-90232-2 1984 ZTT
Phillip Glass--"Mishima" Elecktra/Asylum/Nonsuch Records 1985 W. Germany
These are your basic redbook cds that are exceptional recordings. Pick 'Welcome to the Pleasuredome', 'relax' or 'two tribes' from FGTHW, tracks 1 & 2 from Mishima, and any track from disc 2 of Dream Sequence which IMO may be the best recording on a cd ever!!
For RW: The Pat Metheny and Porcupine Tree recording are absolutely amazing in dts!!
I'm sure you've considered tracks off Jennifer Warnes' CD "Famous Blue Raincoat". Give a listen to "The Hunter", her follow up record. Specifically, the first 2 tracks; "Rock You Gently" and "Somewhere, Somebody " are sonic stunners.
Also consider "Sistas" by the Jazz/Funk singer Rachel Ferrel, which I believe can be found on the CD "Individuality".
PS Good Luck w/the QSonix stuff as well, I can't get enough time with mine!
