Sorry you're having that problem. I used to have all McIntosh gear (MC601's, MC303, C2300, MPC1500, MX151 among others) and when I sent my MX150 back for the 3rd time, I'd had it. They make amps like champs, but buyer beware on everything else is my experience. You're not the only one who's had problems with their gear, but they do produce a certain sound that some people love, which I get. I sometimes I miss my MC303 and MC601's.
I recommend you contact your dealer and relay how upset you are, make sure he gets in touch with someone at McIntosh who will give your player a thorough evaluation and ensure that whatever they send next time is going to work. If you love it, keep it and pray. Good luck, know you're not the only one who's gone through this.
