Got a customer claiming that the 'Crafty COAX' cable I built for him with an RCA connector at one end and a BNC connector at the other is causing 'channel imbalance' in his system.
Of course it's not the cable; an audio coax cable is just a bridge for a single digital data stream that deals in 1's and 0's which is then split into L/R at the D/A stage of his DAC!
...or is it? CAn an audio cable casue channel imbalance?
Suggested he try the cable between completely different source and DAC to cancel out the possibility of the issue being the cable as well as suggesting that it may well be the internal analogue I/O L/R-level settings of his source and/or DAC components, but just thought I'd also canvas opinion here.
For these cables I use Neutrik BNC connectors which are of exemplary quality, Sommer Vector Plus 75-Ohm double-shielded coax cable and an Amphenol RCA connector when called for as in this case. Signal conductor is connected to the signal pin of the BNC and RCA connectors and the shield layer of the cable connected to the ground plane.
Cables are always tested including for this one; continuities, signal integrity/strength and analogue balance using sig-gen & oscilloscope and digital source and digital recorder sending 24bit/192 kHz and 1bit DSD signals before dispatch.
I sell 4/5 of these a week in different configs over a total of about 170 sold in total and this is the first time someone has made a complaint about 'channel imbalance'.
Weird
