bullshit i can hear a difference from the 2006 and my RD 1750... slight but way cleaner and slightly louder(probably from the higher efficiency).. def worth the upgrade..The real answer here is no, you will likely not see much of a difference. If the hifonics is truly overrated by a few hundred watts, you're still only talking a minimal difference when in the 1500w range.
I doubt you'd see an improvement worth the investment.
