It might already be too late and I probably won't change my mind, but is there any reason to go with basic sierra towers over the RAAL tweeter version aside from price? I ran into some random posts about the nrt being better if you watch movies a lot. I do both but music is the priority. I already ordered the RAAL towers this morning but they haven't made them yet. Should I prefer the nrt or stay with the ribbon? I don't care about the money but I need the speakers to be good for both uses. Hopefully Davef will chime in? Hopefully somebody will tell me the RAAL is superior in every conceivable way so I can sleep better at night.
