You will hear detail in your music you didn't know was there. I aver that even my Advent based garage system will do the same, if not to the same degree. Is that good or bad?
As for me, I've always been a resolution junkie. Always seeking better. While I never duplicated HP's
phenomenal system clarity, I always enjoyed the experience. The Nordost Odin cables in his system alone ran about $100k. Even my wife wonders why I spend as much time (perhaps more) listening to the lesser garage system. I'm happy with less, but always enjoy sampling more.
It might, however, alter your perspective. What's more important? A wall of diffuse, non-aligned speakers breaking every rule about optimum directivity driven by redundant lower end amplification or a more focused system for the
same investment that takes you deeper into your music?
Dunno.
