Peter, I have a ton of fun listening to Elvis, Johnny Cash, and, ahem, NWA, in my friend's van, when I occasionally join him on plumbing jobs. Yes, it sounds "better" at home, but there's actually a lot of simple enjoyment to be had from lowly MP3 quality.
Re my dichotomy on a lot of my material being fairly brutally exposed on recent horns demos, indeed I'm now thinking this is the method of delivery to the horns that is the issue, not the horns themselves.
I've long thought that digital does not suit a lot of challenging recordings, flat pans, unecessary overdubs, useless multitracks, hot masters, and murky mixes. Analog both reproduces lower level detail and is more sympathetic in comparision to digital brickwalling and cliff edge treble.
So play material like Rush, Magma, Voivod or early Mahavishnu Orchestra that is much smoother on vinyl, Tidal seems to reproduce this music way starker and sharper in treble/cooler in bass, and once it emerges out of hugely analytical horns, can sound like a hot, disparate mess.
However on the three occasions I've heard well set up analog into excellent horns, this stridency not anywhere near as apparent. Still challenging. But warmer and more effusive.
So maybe my issue is not prog on horns. But prog via Tidal on horns. Or any other uber resolving high end spkr, ribbons, multidrivers boxes.
