Yea I think so too. I demoed a KEF LS50, Monitor Audio Gold bookshelf and a Martin Logan floorstander (Looked like a floorstanding version of the Motion 15). I'd equate the KEF and the Monitor Audio and had overall better sound than the Martin Logan, but the Martin Logan had more detail than the other two.
By proxy, I'm pretty sure an Ascend Sierra-2 is what I'm after. I've heard of the Philharmonitor and BMR, but I don't think the BMR fits well with the intended 2.1 setup as much as a Sierra-2 (not to mention it's also more expensive) and the Philharmonitor runs comparable, but I'm still leaning towards the Sierra-2. Are there any other speakers in this range that I should consider?
