I can't answer the OP question, however I went from base radio in F10 to HiFi speakers in G30... for me it is absolutely fine, loud and clear with good bass for
MY type of music... sitting in back or front it is very nice....
Even at low volume the bass has a great thump, and the mids and highs are clear... just set your bass and treble settings to your preference (for me 85-90% near max)
I don't feel I should have gone for the HK (which I have not heard), quite happy where I am
