I got the 204 today and my first impression is WOW! This thing gives me the sound that I have been searching for, clear and deep yet smooth and bright without being harsh. Everything I've ever wanted from bass tone! Of course this is just the first day I have had it but I am already considering selling my Aguilar DB659, my Q5 sounds ten times better going right into the 204 and into a power amp. Best of all: Everything is adjustable! dial in and out any frequencies you do or don't especially like! Amazing! I just need to see if I can find a preamp/eq that will pair well with this unit, I don't really want to color the sound much. Any ideas for portable (relatively inexpensive) preamps or eq? Something with midrange and maybe an effects loop? How much midrange control do I really need? Raven Labs PHA-1 or true blue? How about this new Demeter beqp-2 preamp box? Fodera? Sadowsky?
