I had Salon1 for 5 years and listened to the Studio2 at a pretty crappy store last month, it was a no brainer for me. I would go for the Salon1 over Studio2. The Salon1 has a much fuller sound to me. The bass is so much better on the Salon1. I really like the Be tweeters on the Studio2 but it does not make up the difference in that full sound. I imagine the Salon2 would be better than Salon1.
BTW - I sold the Salon1 because I moved and currently have my stereo in storage. Next speaker maybe Thiel 3.7 or B&W 802D. I will also listen to Salon2.
