Audio research m300


Has anyone ever heard a pair of Audio Research M300's ? I'm looking for more power for my Thiel cs5i's. I'm currently using a Krell ksa 250 With a WADIA 301 as my preamp/ CD player. It sounds  wonderfully balanced, II'm just looking for a little more volume. 
I would love to hear anyone who's owned a pair of these. 
Thanks, Mark.

The LS15 has a skeletal sound and no bottom end either.  You need to hear a better sounding preamp.  The VAC line of preamps will make you say wow!
anyone know hot to get parts for M300?i ve tried the manufacturer in Minneapolis, they do not answer.
