The War on Wall Warts

Recommended Posts

Wall warts.jpgAfter a long struggle, I've finally purged all the switched-mode power supplies from my audio system, and the carnage in the photo is the result. One 12/5v Keces power supply runs the music server, its Paul Pang USB card, and the phono stage in my listening room, and another 12v Keces in the network/phone/alarm closet powers the NAS, network switch, router, another disk, and an Intel NUC renderer.


The music quality has improved in hard-to-describe ways, but I didn't test systematically to see which change was most effective. It's also immensely satisfying not to have those things radiating out of the surge protectors like, well, warts.

Has anybody also tried powering their Broadband Modem from a good low impedance Linear PSU ?


How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area. All that Identical Checksums gives is the possibility of REGENERATING the file to close to that of the original file.
