Been listening to The Beatles ...

I hadn't listened to any of the Beatles stuff in quite awhile, so I can't claim to be that familiar with all the nuance. I think my last listen was 6 months ago and that was Love on vinyl.
I picked up Revolver and a few others Saturday and listened in my spare system. I was VERY impressed. Heard lotsa little things that I know I hadn't heard before.
The remasters were nicely done, IMHO.

What is better Mono or Stereo ?

Yeah, they sound great. The early albums' strength is an infectious joyfulness.

I think that if Traffic had kept Dave Mason and not gone off in that jazzy direction but stayed in the classic rock vein, they might have given the Beatles some competition.

Listening to remastered Abbey Road now and lovin this one. I'm making my way through the stereo box set slowly.

"The early albums' strength is an infectious joyfulness. '

That is a very good observation.

The early Beatles recordings and performances, when they were doing their versions of the "rock and roll" tunes from mostly American artists that they grew up on are largely under appreciated compared to their later output where they broke new artistic grounds.

If you appreciate how the early Beatles did joyful and infectious "rock and roll", be sure to check out the "Live at the BBC" set in addition to the new re-issues...it is a gold mine in that aspect.
