Please explain mono

Thanks all.   I think I'm understanding. ...and to you mr.wolfie62,   sounds like you know your sh.. not sure I'll ever be on your level but thanks for the passionate explanation.  Im new to vynle so everyone's expertise is appreciated.  What sparked my question was that I bought a jimi hendrix  are you experienced lp and when i got it home realized it was mono.   Stupid me....but then I thought that there must be something to this mono thing or they wouldn't be reissuing mono lps and there wouldn't be mono settings on modern avrs or integrated amps.  Plus I have a bunch of classical lps from the 50's and 60's that were my dad's. I think I need to do some tweaking to my set up to so I can hear what some of you are explaining.  

Cheers!!

The guys who recorded Louis Armstrong's Hot Fives & Sevens all wore ties to work and worked in mono. That's why their work sounds great nearly 100 years later. 

Back to Mono!

WOW…400 mono records! 

Your dedication to achieving the best possible mono playback is quite remarkable and awe-inspiring. I am still baby-stepping my way to optimizing monaural Vinyl playback. Hoping to wrap up my setup with a secondary GrooveMaster 4 tonearm and Miyajima Zero. 

Unless the quality of the stereo version is awful, I'll generally go with those and not the mono. Among those 'awful' stereo versions are those early Beatles records where all the vocals are in one channel. Those I go with mono every time.
