Hi everyone, I need some help troubleshooting my desktop audio setup (sorry if this is in the wrong thread!)
My current setup (admittedly budget):
Laptop USB3.0 --> Musiland Monitor 03 US Dragon --> (generic) Toslink SPDIF --> Audio-gd NFB12 --> Monoprice RCA 1.5ft --> Schiit Valhalla --> Sennheiser HD600 (stock headphone cable, 1/4 no adapter)
The "signal noise" (low volume crackling/static and/or high pitched noises) I'm hearing happens after about 30 mins of listening, and is usually masked by music. I only notice when music volume drops or between songs, but is very frustrating and noticeable on quiet/slow classical pieces.
I use the Musiland Monitor because I listen to many files at 192k, and the Monitor lets me supports those files on this setup.
-Removing the Monitor from my setup and the signal noise cleared up, but I'd like to find a solution to keep it in my setup. I think the sound quality is noticeably better with it
-Changing the tubes in the Valhalla (no change)
-Updating to latest Monitor driver (minimal benefit; signal noise used to be always present, and now onset is after a short period of listening time)
-Changing headphones (no change)
Any help would be greatly appreciated!
I'm planning on upgrading the cables in my setup to Blue Jeans cable since they're comfortably within my budget, but there is some leeway if other reasonable suggestions are available.
Another solution I'm willing to entertain is to remove the Monitor and upgrade my DAC, possibly to the Schiit Bifrost, or similarly priced DAC, though this would be last resort since it would probably be the most expensive option.
