Hmmm...
this is not my experience with my "same spec'd Valenti" which is much more grindy and punchy than the RV.
The Valenti just kills, driving right thru the mix, and is very aggressive.
The RV5-with the hc's being the only spec difference-does deeper, and higher-but seems much more polite, hifi, and has a voice that doesn't meet my personal needs.
True that the AC is more old school, yes, but, it too has a direct punch and grind the hc's don't do, for me.
Flip the RV and be happy then
