Interconnects/Cables of your choice, and why?

Most of the time during the last 30-odd years I've used interconnects bought from Best Buy, back when they sold stuff by Monster Cable. Never thought much about the finer details, so they sounded all right by me. I still have a few pair that I use for short-distance connectivity.

When I began to upgrade some stuff in my system after a lightning strike, including new components, I looked around on the Internet and saw that Blue Jeans cables were viewed favorably in the group of low-cost/better quality interconnects, so I replaced some of the interconnects with those. I also use Blue Jeans cables for my coax connections between my CD transport, my Wyred4Sound Remedy Reclocker, and my DAC.

For the longest time of anything in my system I used 12 gauge copper speaker wire from places like Best Buy, Home Depot and Lowes. After looking at some photos from Morris Audio about their speaker cables, I started experimenting a little on my own with smaller gauge copper wire.

Right now I'm using stuff I bought from Amazon to create my own speaker cables: (1) 24 gauge 99.98% pure copper wire (or so they say); (2) copper foil tape; (3) 1/4" OD / 3/16" ID clear vinyl tubing; and (4) better quality banana plugs. I think this has made a drastic improvement in the overall sound of things.

Does it sound like the stuff most everybody listens to on this forum? Probably not, but I'm happy with the results. CDs, LPs and FM radio sound more spacious, lifelike and natural to my ears, and there doesn't appear to be any interference coming out of my 1994 Vandersteen 2ce's during playback.

If I upgrade anything else anytime soon, it'll be a better tube preamplifier. Seriously considering the Icon Audio LA4 MKIII that's advertised on this site.

Speaker: Audience AU24SX

Exceptionally thin, light, easy to manage, yet sound superb. I've tried others, and have always returned to Audience, with a few upgrades over the years.

XLR interconnect: Audience AU24SE

Haven't tried many others, but feel no need to do so.

Power: 2x Ansuz A; Ansuz Mainz P2; Hijiri Nagomi H-DC1115; Shunyata Black Mamba

All excellent, in my system, and connect to the also excellent Mainz 8 X-TC "high-end audio power distributor".

AES/EBU: Kimber Kable KS2120

The only cable that I've used between my Dacs and CD player.

USB 2.0: Supra Excalibur 

relatively inexpensive, but the music, including DSD files, sounds terrific coming from my Mac Mini M2..

In my "big rig" all line level interconnects are Cardas Clear Reflection; this has replaced a mix of older Golden Reference and Clear Cygnus.  Balanced from DAC to pre, otherwise RCA.

The Clear Reflection cables are perhaps (definitely?) just on the warm side of neutrality, but, at line level, seem to do no damage.

The phono connect is a Transparent Super Phono.  I tried Cardas in that position but the sound seemed to lose air and space.

USB is Cardas and Ethernet cables are whatever - my Esoteric K-01XDSE DAC seems to be completely insensitive to its digital input provided the data is correct.  It is my experience that today's well engineered DACs are relatively insensitive to cables, unlike the situation 30 years ago when jitter on the input to a DAC was a serious problem.

The clock cable is a 10 giga Hertz bandwidth broadcast level transmission cable.

Power is from a Monster Cable surge protector/filter.  Amplifiers are connected via MIT Z-cords, other equipment via 16 ga. "hospital grade" power cables.  My equipment is on a dedicated line from the panel, I am the only house on the line from the 13.8 kV (I think) transformer 100 feet from my house.

Single ended interconnects between my dac to preamp and preamp to amp are Black Cat Silverstar 88. Unfortunately, they are no longer available.

Acoustic Zen mc2 digital coaxial cable. 

Graham Slee CuSat50 interconnect elsewhere. 

Just bought a Veritas Optimus 50 hdmi/I2s cable.  So far, it's sounding quite good. 

I like silver.
