Interconnects: Mogami 2549, Mogami 3173, Mogami 2964 for SPDIF if needed, 'Ghost Cable' from a mastering person, and Grimm TPR. Some of these are 110 so can and are used for digital analog both. All these sound different from one another in analog usage. For digital, cabling variety can matter, but so does length.
Power cables: Unshielded stock cables everywhere (14 AWG and 18AWG) going into Torus or Tripplite in different systems.
Speaker cables: Amphion speaker cables in the passive all Amphion system. The other 2 systems are active so just XLR interconnects. In the low-end passive Marantz system in the casual system that gets used once in a while, I use random speaker cable bought from Canada Computers.
(I only experiment with balanced analog/digital interconnects with their quick Neutrik swapping. The speaker cables are a headache and take forever and so those never get touched, and thus have been a constant for years.)
Ethernet: I have all kinds of 5e, 6, 6a in UTP varieties, and shielded varieties up to S/STP. I have settled with Belden bonded solid core Cat6 UTP that I use with the Bryston system along with Teradak LPS for the switch.
USB: Way too many (50+). Notable ones include Belkin Gold and Audioquest Forest. Some of these USB cables along with ethernet cable have been individually tested on Fluke analyzers to assure that they can meet and exceed the specs required. I like to know how the cables are made (design) and how they measure.
