I got the Beatles Mono box last year, and was blown away by it. I may have had an out of body experience while listening to Sgt. Pepper pumped out of all my speakers. Or maybe I was just really exhausted at the time.
I miss Ringo yelling "I got blisters on me fingers!" at the end Helter Skelter though! ;)
And I did buy all the albums that were true stereo as well.
