I have a Diggi 02 rack with api 3124(4 channel) preamp. I would like to have at least 4 more channel so I talked to my friend about getting a quality preamp channel and he tell me that even if I get a $5000 preamp is gonna sound like crap couse it have to go through the diggi preamp. Is that true? even if i have something like the focusrite 8 preamp channel LE.What is the difference between the Focusrite OctoPre LE 8-Channel Preamp and the Focusrite OctoPre 8-Channel Pre-Amp. Im sorry for this stupid quiestions but I'm just a DRUMMER!!!
