I am currently running a Mcintosh C2200 preamplifier (now discontinued) and have recently been afforded the opportunity to upgrade to the C2300. Not being in a position to audition the C2300 beforehand I'd be very grateful for input as to whether this would be a worthwhile change. Please note I'm only interested in the C2300's performance as a preamp as I'll be using a stand-alone phono stage.
