david, i'm considering the newform research nhb645's or r645's.
angela's point about "hunting instinct" is well-taken - i paid <30% of retail for my current speakers, & i'll have to pay full-boat for the newforms - it'll totally ruin my 3:1 retail-price/paid-price ratio for my system! ;~) but, hopefully, it will exponentially improve the sound of the system, compared to the sound of *cost-no-object* systems... :>)
regards, doug
