I just came back from MXL - these guys are GREAT. They looked it over and immediately owned the problem. It looks like somehow or another it was shooting straight voltage from the power supply through the mic cable. YIKES!
So, to make it up to me, they
1) Gave me a Genesis in exchange for the 960
2) Called Summit to arrange for them to fix my preamp
3) Are currently looking for a suitable replacement for my sound card.
Roy, Jim and Hank have been champs on this situation. The service they showed me today has made me a big, big fan of MXL.
I may not be able to record til I get the soundcard, but I feel like I can sleep a little tonight!
BIG THUMBS UP, MXL !!!
