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

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..

+1 for Signal Cable. 

I also have several 2M Transparent Audio MusicLink cables. Those are the best-sounding cables I have...

Hello:

Have you thought of making your own cables?

Get the raw cable from Beldin, mogami, or other company that make the raw cables. Then get the connectors from company that make connectors like Furutech. Get your solder and soldering iron and you are on your way.

Most companies that make interconnects don't make the cables or connectors, they just assemble them and make them look pretty. 

I have purchased very expensive cables for my audio system and upgraded several times. But it came to a point where I performed listening test with my executive cables and cables I made up myself using Blue Jeans cables, mogami and Belding cables and I when I compared my DIY cables with my expensive cables I couldn't tell any difference. The reason I went DIY is that after purchasing the expensive cables I immediately heard a difference in the system, but after a few weeks that excitement wore off and I began to wonder why. No answer than to say because it's expensive it must sound better. Nonsense. 

Try some DIY cables and judge for yourself, only you can decide what sounds best to you. There is no magic bullet in this hobby. 

Grover Huffman. Had to go to AQ robin hood to equal sound quality on my rig settled on Wild for speakers 

I have had good experiences with Morrow Audio MA7 IC's and speaker cables.  reasonable prices and a nice sounding wire.  I preferred the MA7 to MIT shotgun 1.3's and Audience Au24 speaker wire, both of which are also great.  Morrow punches above its weight class and they give you a large credit if you want to upgrade.  Very nice company to deal with.  I have to disagree with @fpomposo in one respect.  I highly doubt that one cable "blew away" another cable.  The differences between cables are not "OMG, its a different system" although there is clearly a difference between cables.  Plus, it is a function of how resolving your system is.  The more resolving -- like in the stratosphere, the more things like cables can be noticed.  I had Focal Diablo Utopia III's with a Pass Labs 250.8 and an MSB DAC, and I could prefer the MA7's over the MIT's for example.  Was it a "blew me away" difference? No.  Was there a subtle improvement? Yes.  When I got Wilson Sabrina X's, I upgraded by speaker cables from the MA7 ($700) to $4000 Shunyata Alpha's.  There was a solid improvement -- definitely better.  But was I crying with dissatisfaction with the MA7's? Not at all.  I was perfectly content with them but got upgradeitis, and there was really nothing more to futz with besides the cables.  So take all of this with a grain of salt.  Cables in your system will not "blow you away."  They can and will make an audible change, but how audible is ear and system dependent.
