Re 'Pet Sounds', Brian Wilson certainly mixed it in mono and I prefer it that way, but a stereo version was released in 1966 and I think when it initially got a cd releases it was the stereo version...I may well be wrong though. It sounds terribly dated to me these days (lyrics, not music or arrangements) although I do still play it and enjoy it. Must dig it out in one form or another.
I don't prefer everything in mono to be honest; I just started collecting monos when I realised the mixes were sometimes very different: 'She's Leaving Home' in stereo is awful: it's much slower and dirge-like compared to the mono. God only knows why they did that. On the other hand, The Pretty Things 'S F Sorrow' is far better in stereo: much clearer and the effects really don't make it in mono...it sounds muddy and cluttered... to my ears anyway.
'Abbey Road' is ridiculously overrated: it's clean, well-produced and competent...the best sounding Beatles record but it's got a lot of dross on it!
The Kinks in mono...yep. Agreed. i played 'Something Else' the other day and it sounded great in mono. 'Face To Face' is the one I'm still looking for but it goes for about £200 these days.
The great Dylan records from 'Bringing It All Back Home' to 'Blonde On Blonde' are much punchier and more powerful in mono I think. More focus on the band,
Incidentally, many UK monos of US acts were fold-downs from the stereo; if you want mono Doors records, for example, you need to find the US releases. I have mono UK's and they're stereo fold-downs. Actually, come to think of it, the whole mono/stereo issue is a nightmare, albeit an interesting nightmare.
Just my thoughts of course.
