I will gladly take a listen to the King Crimson album. King Crimson in general is a very different type of rock similar to Pink Floyd. I have been a fan of King Crimson.
If I were to just listen to rock.....Van Halen, Bob Seger, Jethro Tull, Who, Rolling Stones, Bon Jovi, Metallica etc etc, then I would just get a good SS amp and dynamic-sounding speakers. Again, that would just be my preference and it would have saved me thousand of dollars...lol
On my system, which is Aries Cerat amplification, Lampi Horizon DAC, Lucas Audio Music Server, and Viking Acoustic Dual Horn Grande Voix speakers.(soon to be Aries Cerat Aurora speakers), I just have not heard many rock songs that from the production level just wow me. But when I have friends over and they want to blast that type of music they love it.
It boils down to my tastes during a critical listening session are different than anyone else. Everyone has their tastes. Cheers
