In a perfect world, consumers would have embraced reel tape--at least for quad recordings. Some did, but not many and not nearly enough--reels always wound up a niche thing, since beginning in the mid-'60's. Regardless, the reel offered the best *potential* sound quality and separation of any format, including vinyl.
Convenience and reduced size, really.
The SQ definitely does not decode anywhere near as discretely as the tape from what I can see, which is a real shame - it could do with more seperation for my tastes!
The SQ LP wasn't anywhere near as complete, even when played through a Tate SQ decoder. It took on a more "ethereal" effect, which suited the music but didn't match the Q8's separation. The mix sounded completely different.
Ugh ... last thing I wanted was another discussion of The Great Quad Formats That Could Have Been. SQ, QS, EV, CD- 4 ... "they are all equal now." Most sincerely dead, as they should be. Vinyl belongs in the adjacent gravesite, but isn't yet because it makes such a good-looking corpse.
And durability. CDs certainly aren't indescructible, but you do have to put a bit more work into damaging one vs. a record.
I wasn't aware that Columbia ever released quad reel to reel tapes. In fact, I've never seen one, nor have I seen any in any quad software listings. The only tapes I'm aware of from Columbia, and its associated labels, in quad were Q8's. Where did you see/hear BOTW on quad reel?
I know they recorded the album "Bridge" in 16 channels separately
Now the question is: Where is the 16 channels analog tape multi tracks??
why they do not convert this tape 16 channels to DSD digital??
(with 16 channels in the hands they can to do a new mix 2.0 and 5.1 surround)
