I agree streaming has been/is often problematic, though I’m at a loss to explain why, and not all sources or solutions are bad IME (i.e. the issue appears to be one of implementation, not concept). That said it doesn’t excuse the rooms using vinyl or CDs. I’m pretty much at the point now where if I see a big heavy MDF floorstander I know it is going to sound like crap from my priorities. The larger, heavier and more drivers a speaker has the more crap the end result IME. There is just something so dead about that kind of construction, it just sucks the music out to my ears. I find it depressing that this is where speaker design has ended up.
PS I need to caveat this in that nearly everything I’m describing has an underlying MDF construction even if it has fancy wood stuck on the sides. I’ve not heard enough machined alloy, carbon fibre etc speakers to form an opinion there. It may just be the MDF I hear.
