If a vintage Oberheim is anyone’s desire then I think most would say the OBX8 is going to be the closest anyone can get (I certainly feel that) - save an actual vintage Oberheim! Amazing synth for sure.
I’m not questioning your view, it’s all subjective after all - I was just surprised about the pad only comment but fair enough, as you explained you were after that certain vintage thing and you didn’t get that from the OB6.
In regards the original question, OBX8 or OB6, it’s just like comparing any two synths, especially as people are saying they sound significantly different. Really depends what you’re after.. for me and what inspires me it’s the OB6, but I wasn’t necessarily after a vintage Oberheim replacement. Rather I was after an inspirational poly synth, and the OB6 has some kind of magic about it which I love.
