Has anyone had success driving their Thiels with Modwright KWA 100SE? Dan's response via email struck me as honest but maybe conservative - he said "The Thiels are a high current speaker and difficult load. The 100SE can drive them, but not as well as a more powerful amp. A load like that might even trigger the amps over-current protection." Which is too bad bc I really would love to hear this amp.
Currently greatly enjoying my setup of Sonic Frontier Line 1 -> BAT VK-55, which is only rated at 55 wpc but sounds exceptional until 92 dbs or so. Also tried an NAD M22v1 which sounds too squeaky clean in general but is much better at higher volume levels.
I have CS 2.3s btw and am still thinking about modifying the xovers as well.
My two cents on room and speaker placement, just keep experimenting with placement and room treatment. For me clearing the space between the speakers by moving rack to sidewall and using heavy draperies and/or diffusion on front wall made a big difference.
