I purchased a pair of matched Peluso CEMC6 mics back in early May only to return them about a week later. The problem I had was with the noise level of the mics (and also a bad roll-off switch). I know the mics are spec'd at a self noise of 14dBA, but they were by far the noisiest mics in my collection (Kiwi, NTK, AKG 414, AKG C3000's, several Chinese condensers, and even my 57's and 58's). The noise was a mix of loud hiss (not environmental as all recording was done in an eerily quiet Whisperroom) and ground loop hum that was unique to these mics. My studio is properly grounded and none of my other mics/equipment show this problem. The hum would get extremely loud if you ran your finger over the pad switch w/out actually touching the mic. Very strange. Tried them through Great River, Grace, Aphex, The Brick, Mackie pre's all with the same results. I even took my Mackie 1604 over to my friends and sure enough, same thing. Then on one of the mics the roll off switch would make this loud crackly noise until you played around with it. Sound/tone-wise I thought they were very good -tried them on drum overheads and acoustic gtr. The noise issue was the deal killer though, so I ordered a matched pair of Gefell M300s which are scheduled to arrive Wed. Wasn't going post this info until I received the M300s (to compare), but since the topic is going, what the heck.
