Mono record sounds like stereo

So I have been playing stereo records for 40 years.  I’ve recently acquired some Verve Japanese reissues. Listening to Metronome All stars tonight and there is clearly separation. I hear horns predominantly on the left and xylophone and drums on the right.  This is on an Ortofon SPU synergy stereo cartridge. Is this normal ?  I’m sorry.  I’m new to Mono.  I bought about 50 verve and Blue notes last week and got some monos on accident.  My system is balanced and the room has extensive treatment so I’m lost !   


Mono records sound great of axis. Once you get in the right listening position a mono record will sound as if you are listening through a crack in the door. If this is not happening one would have to assume there is a problem with your system's stereo imaging. 

I’m listening on an Altec A5 horn system and I was so impressed with the sound quality of this mono record.  Thank you for the response. I thought I was crazy or my preamp was broken LOL 

A well recorded mono LP is an attention getter.

Period press of straight ahead Jazz on Contemporary, World Pacific and Riverside are a few of the other labels that do the magic.
