I am auditioning the Lamm LL2 right now and have the BAT VK-30SE and Pass Labs X-1. The BAT has compressed dynamics versus the others and has a darker background. The Pass sounds much clearer and more dynamic than the BAT. The LL2 compares to the X-1 and has a more tube upfront/forward mid-range sound. The Pass is a little more dynamic than the Lamm with slightly more detail. I have not heard the BAT VK-50SE in my system but it should be X% better than the VK-30SE.
I also just received an email from a guy who buys and sells dealer demo units and he told me that he preferred the X-1 to the Lamm LL2 (currently being sold here on Agon)and the Hovland. YMMV.
