Less barking, more wagging!
You make a lot of valid points. Some amps have a baked-in sound that's optimized for so-called bedroom sound or studio tone, while others are much better tailored to suit live performances on pro stages.Not interested in nostalgia for gear, unless it is gear that I own and keep / use at least in part for the memories, and I wouldn't purchase 'another' of a piece of gear I sold before to replace it out of nostalgia. Old gear is not generally better, not better made and mojo is just BS justification for something not so great, but usually expensive.
Class D amps are better in every regard than lead sled A/Bs, speaker drivers are often better, but it's incremental refinements.
Instruments, mass produced ones at least, are typically better made and far more consistent than older ones.
Tone I'd rather was 'bright', wideband as it's easier to EQ it down to a thumpy tone than to make one bright. I want my rig to be able to cover most genres.
Playability is about set up and QC, and the latter is better in more modern instruments.
My preference is for simple, reliable, lightweight gear that gives my "my sound" using loudspeakers no larger than necessary,and used in multiples for larger venues and outdoor gigs.
