How can you tell if a recording is in mono?


I am listening to an SACD pressing of Coltrane's A Love Supreme. I noticed that the stereo imaging was basically non-existent-- Trane is coming from the left channel, drums from the right, with piano and bass in the middle.

Since I have a preamp with a "mono" switch, I used it, and the sax and drums came right into the center along with the rest of the band. However, the sound lost a lot of its sparkle.

Not really sure what's going on here, and would love input.

Thx

Personally I hate mono and the early sixties ping pong stereo inspite of great music of the era - John Coltrane, Miles Davies, Sonny Rollins to name few.

I stay away from any recordings prior to 1959 and early sixties. IOWS, anything recorded before 1959 would be mono ( someone pl, correct me if I am wrong) I am talking about the ones available on CDs. As good a digital system I have (IMO), the re-mastered recordings ( classic jazz) from this era have that high freq tinge around analog notes that it is annoying. (may be the inorganic nature of the recordings has something to do with it) Same recordings played back on LPs are much more bearable though. Not great but bearable. I am referring to Jazz recordings. Classical recordings on the other hand from the early stereo era on Vinyl sounds great.

IMO, recording technique/s have come a long way ( excluding compression mastering taht is on going on commercial releases). May be I am getting way off topic....
