rogue 66 vs vtl 2.5 linestage

VTL makes great tube amps but I've never heard their preamps. I own the Rogue 66 and it's a giant killer. Very nice, warm preamp with good bass. Highly recommended. The 99 is even better, if you can go the extra scratch.

I cannot tell you about the Rogue, but I would avoid the VTL. Preamplifiers are something the Manley's have never gotten right.
