Yes so, all the superlatives that read as positives, I will not bother you with. My serious listening impressions from listening to just 4 reference material cd's via my Sony MegaStorage 300CD player has convinced me that while many similarities exist, this is a different animal indeed. Another thing is the bass. While the footprint or stage seems more focused. the bass is sufficient for my needs so far. Configured as an apex at my corner computer station/desk, I am near-field of course while at the computer. In this position the Tractrix sounds much alive and crystal clear. When critical listening after towing one speaker outward a few inches in order to listen 15 foot way at a comfortable chair, I was much impressed wthe center balance of all of the speakers. I will no longer worry about not having enough bass with the reference line of speakers. Looking forward now to the RF-5, RF-7 and not necessarily in that order. Very pleased with these speakers powered by the Carver A500X. So pleased in fact that CD's that I have heard previously, are now listened to with relish, like a new life has been breathed into them. All for now and thanks. RF-3's can rock, etc...
