I recently purchased an AK240 and a Schlit Mjolnir amp that are connected via Moon Audio balanced cables (2.5mm TRRS to dual XLRs) and auditioned via Audeze LCD-3 (Moon V3 cables). I immediately became aware of RFI and what appeared to be a ground hum when the volume control was advanced beyond the 12:00 position. I then connected the amp's power cord to a Furman Elite 15 PFi which eliminated the RFI but the hum has persisted. I suspect that there is some persistent "antenna" effect, since moving the AK240's balanced cable produces some crackling and, depending upon the position of the cable, variance in the intensity of the hum. Is this the result of connecting a grounded device—Mjolinir—to an ungrounded device—AK240? And if so, is there a solution, short of replacing the amp with a portable device? Has anyone had experience with the EBtech HE-2-XLR Hum Eliminator?
Thank you in advance.
