I have absolutely no idea under what mechanism bad XLR cables would cause hiss. At most, better shielded cables would reduce noise.
Nor do I. Buit the entire question as posed is a mystery.
What cause tweeters hiss ?
I could hear hiss sound when i place my ears close to both tweeters (ATC SCM 11 speaker) when Denafrips Ares II is connected with interconnect (XLR or RCA) during power on/off/standby. Hiss sound disappear only until power cord is disconnected.
At first I thought it’s amplifier (Accuphase E280), then I bypass Ares II and connecting Sony CD player with RCA out to amplifier, no hiss can be heard from tweeters.
Due to curiosity, i connected my Topping D90 with similar arrangement, I could hear hiss sound until I unplugged power cord.
During the above test, music is stopped, amplifier is turned on but at zero volume. All my music source, DAC, amplifier are from the same power source/circuit with Novaris Power Filter.
Can’t hear the hiss at my usual listening spot though.
What could be the culprit that create this hiss, DAC ? Grounding Issue?

@auronthas Interesting article, thank you for posting. I agree with you about the cable, it served a useful life. Not sure what to recommend to replace it, different cables have different sounds and some equipment works better with some than with others. You just have to try different ones and let your ears decide. |
One thing to note ... my old Cardas XLR cables are longer 2m each, new one is 1m. A longer XLR cable may subject to noise interference than shorter one. Also the 15 years old XLR may not have a good shielding against WIFi ... perhaps. Some of the answers are funny though. You guys make my day more joyful. |
