I went from Salk Song3's (standard version w/bamboo midrange) to a pair of Clearwave Duet 6 monitors and a pair of REL T5i subs.
First, both systems sounded great but there were tradeoffs probably because the speakers are different. The Clearwave's use accuton ceramic drivers vs the RAAL/bamboo/paper drivers in the Salk. With the Clearwaves and RELs the bass was more detailed, tighter, more accurate. I preferred the RAAL in the Salks to the ceramic tweeter but not by a huge margin. The RAAL just gets an airier presentation I prefer. Overall, I thought the Clearwave/REL system was more detailed, more accurate, and had better bass. However, I never tried the Salks with the pair of RELs, but I was pretty pleased with the Duet 6/REL combo and while I've moved on to Cube Nenuphars, I wasn't feeling like bringing the Salks back to replace the Duet 6/REL combo.
