Interesting, I have owned a vtl 2.5 for a couple of years and I think for the money it is a great value, I too have heard other preamps in my system, and I still say for the money the 2.5 is a killer, I know the local VTL dealer sells alot of them with vtl amps and ss amps,but we all hear what we hear...no substitute for listening to one at home if you can.
