I was selling my Sanken CS3 (not e) since I've heard the e improved upon the noise floor and thus the cs3 was noiser. Then I tested my friend's Sennheiser MK66 and it was also noisy within the same setup. Thus I think it's my setup instead. Could someone help pinpoint what could be the issue?
Sanken CS3 to Mix Pre D via XLR
AES from Mix Pre D to Digital In of Marantz 661
i've tried different xlr cables also.
