Hi, I'm looking for to upgrade my recording chain. I am currently using an M-Audio Tampa as my main preamp. I have read good things about the Chameleon Labs 7602, Focusrite ISA One and Daking Mic Pre One and they seem to offer excellent performance and value. I've been offered a secondhand Chameleon Labs 7602 for a good price which means I could keep my Tampa and buy the 7602 giving me two flexible channels. Alternatively I could sell my Tampa and buy the Focusrite ISA One or Daking Mic Pre One? I'm a little nervous about putting all my eggs in one basket as I do record Acoustic/Electric Guitar, Upright/Electric bass and occasionally brass and like having a couple of options/tones to choose from. What are your thoughts on this?
