I'm also curious about the vinyl experience from those here saying that the notion of warmth is incorrect. I don't mean this in a nasty way, but are any of you old enough to have actually spent hundreds of hours listening to vinyl back in the 80s and 90s? If not that might have something to do with our perception difference. It might be reasonable to assume that todays gear is less warm than the vintage solid state gear I grew up with. Perhaps not, I'm just speculating.
*cough* Yes. I was listening to vinyl in the 70's. Back then we just called them "Records." But that was a new idea, vinyl. I also owned an 8-track, and lots of cassette decks and tapes. I stored the first computer programs I wrote, created on a Radio Shack TRS-80, on a cassette tape deck.
When I got divorced, my ex wife made off with a whole pile of our cassette collection. Once a car of mine was stolen, and when I got what was left of it back, the 8 track deck was one thing they kept.
And when I was a kid, I used to record the Beatles onto a small reel-to-reel tape deck, using an AM radio as the source. I even sang along with them. Go figure.
We didn't so much discuss warmth back then, as how to make records last, and how to get rid of the pop and click noise that would plague us after listening to those records for a while. In retrospect, I really wish we had found a way to protect records from physical wear. I'd love to have some of those old records back, that are irreplaceable.
I would suppose that we're now discussing warmth, because we have audio gear that is so much more capable of reproducing accurate sound, than anything the average person had, 40-some years ago. Compared to the uber-accuracy of today, it might just be considered a kindness, to describe music of that era as "warm". Personally, I think the SQ of recordings 40-odd years old really suck, compared to today. Just listen to some old original Led Zeppelin, then compare it to Celebration Day. 'Nuff said.
