I'm very intrigued by the JTR 215RTs!
I don't doubt that they have excellent dynamics, dig deep, and that they crush in a home theater setting. However, can those who have owned or auditioned them speak to their musicality? I'm especialy interested to know how their musicality compares to other floorstanders in a similar-ish price range, e.g. Salk Veracity HT3, Dynaudio Focus 3XX series, PSB Imagine T3, Golen Ear Triton One (a little less), B&W 803D3 (a little more)? I'd use these guys about 50/50 for HT and music. It would be a rare day that I'd deliver them anywhere close to their power handling capacity, but I do like Gene's theory that speakers that have been massively over-engineered from a mechicanical point of view will be highly linear at lesser volumes.
