Debating if I should spend over three times more ($1,100 vs $3,400 when comparing on the used market) to get the newer Revel F52 or go with the F30's. I listened to the F52 last week and loved it. Listened to the F30 five years ago and also enjoyed the speaker, I have no way of comparing these side by side. Is it really worth 2,300 more for the F52? Most Revel dealers are of the opinion that the 52's are much better. Anyone out there had a chance to compare these two speakers.Your opinion?
