Alas, when an upgrade to an existing speaker costs more than the street price of a pair of, say, Revel Salon 2s, it's time to move on and consider alternatives...
I used the resale money from the Salon 2's to buy my DSP8000.2 and after posting interest in the SE upgrade waited.
I can say the Salon 2 has an excellent tweeter but I couldn't get them to sing! My 250/425 WPC Hegel H360 wasn't enough to get those bass drivers to budge and after rereading the reviews, 7' off the front wall, 53" apart, miles away from side walls, 11' back with the listening chair etc. After 9 months I gave up and I got better sound from the base 8k from the start. When I considered how much money I would potentially lose mixing and matching amplifiers to a quality pair of passive speakers I decided the on the SE kit, if a deal can be found is worth it.
