If you had $1500 to spare, and a chance came your way to own an Avalon 737, would you buy it? $1500 is a LOT for a pre amp, but I think the U5 sounds .... like the best there is!! Especially EQ Curve 2. So I'm thinking that the 737 must just be head over heels more flexible, possibly better sounding, and just ..... Freakin great to have. So, Would ya??
