What cable companies make the best cables and sell them directly?

Chin Audio Labs.

Sometimes a direct seller is less likely to discount so as to avoid being accused of undercutting their secondary retailers. Sometimes returns are only accepted for replacements and not refunds. When dealing with a direct seller those replacment options can be much more limited than can sometimes be the case with a secondary reseller that might carry additional lines.

+1 AntiCables

The ICs and SPKR wire are well made, reasonable in price (basic to exotic) and available in both custom sizes and connections.  

I have used Audio-Envy cables for all of my RCA analog interconnects and speaker cables.  I have found them to be really musical and balanced across the frequency spectrum.  Captain is the owner and is happy to work with you and I believe they still have a return if not satisfied policy.  I highly recommend them for sound and price.  

Audioart Cable speaker, power, and interconnects have worked well for me. And Rob at AudioArt Cable is a great help. My woo audio wa22 headphone amp uses a anticable powerchord. I have been playing with considering the fidellium speaker cable. Jeff there is a great guy to talk with. I have mixed gold and mixed silver and rhodium between different components and noticed I could tune my system that way as others have mentioned in this thread. Hence the anticable power cord on the headphone amp (a tube amp). However, i did spend a bit on usb with wireworld platinum (started with a audioquest carbon). I also agree with others here that if you have the time and money to find the right synergy to your system, the Cable Company rentals can be helpful. I also found cable does get better with a little time; makes a quick analysis on new cables in a comparison a bit difficult. I have a friend using silver smith and fidellium and loves them in his system. Definitely look for some video reviews on some of the brands you are reading here in the thread.that is how I found AudioArt Cables (a New Record Day video review put AudioArt Cable on my radar). My system is a mid system, schiit mono aegirs, and bedini amps, to shahenian obelisk speakers, a schiit yggdrasil, and a freya+ with the woo wa22 and audeze headphones. I don’t think my system is in the same league as yours. However, there is a theme here with my system, how much sound value can I obtain at what is a reasonable cost to my income. I have tried a few other cable brands (cullen Cable, nordost heimdal II, blue jean, audioquest, and they are all in a box. ;) but you know this hobby…. Sky’s the limit and diminishing returns and all. i tuned my system to where I was enjoying the musicality and called it a day. Cheers and good luck..
