Don't most good preamps have a polarity reversal swith?Seems like an overpriced phono preamp that doesn't allow you to adjust ANYTHING!? Like you have to get inside and change resistors just to adjust the input imped!!.(And this is from a hugh ARC fan). I haven't really done analog for a long time, so is this typical? I think i would look for a phono stage that has a allot more to offer. Just some idle comments.:)
