Humming stopped - new cable the solution
It's a long story but over the years, I've tried a number of interconnects (all under £100) but have nearly always been plagued with varying degrees of background hum on my system. Managed to stop it once with a set of balanced xlr between the dac and power amp but it returned with the purchase of a linn majik dsm feeding a separate power amp (I wasn't too keen on the Majik's built in power amp).
I upgraded my Roksan LIII power recently with a Caspian M2 and was very pleased with the results. While giving it a rare burst of loud throttle, however, I again became very aware of the dreaded 'buzz' when the music stopped. Now I'm not going to knock the DSM resin interconnects because in a buzz free environment, I'm sure they will sound great. After yet another search for buzzing solutions, I came across a recommendation for a well insulated cable that may help. At only £40, the Atratus RCA interconnect seemed like it was worth a try so I ordered a pair.
The new cable's now been in the system for about 10 hours and I've got to say that the results have been very impressive. Virtually no hum even when the volume's up loud and the sound is spot on. Don't want to start waxing lyrical about cable sounds because I know that this would start the usual cable wars responses. Just a suggestion for anyone else out there with 'buzz' issues. It might be worth changing your interconnects....
