What a gorgeous looking system!
What is the tube amp in the picture? Do you use that for bi-amping or is the Rowlnd just being used as a pre-amp?
I also have a pair of Glenair's, and I am using a Classe DR-3 twenty five watt solid state class A amp with them. It has enough juice to get the wine glasses on the table moving, so I can only imagine what 250 high quality watts would do with those speakers!
Thanks for posting your system.
