I currently have a Focusrite 18i20 interface. Nice 8 xlr input interface and works really well. I'd like to see about a getting a dedicated single channel pre, comp, and eq to use with vocals. I don't want bargain entry level, but something that would be a mid-budget offering. Especially that would have enough gain for low output mics like an SM7b. To give you an example, I've been looking at the Golden Age Product pres. I'm not opposed to a 500 style lunch box but I'm ok with it being a rack or desktop base. Any suggestions?
