I wouldn't hesitate to buy from The Cable Company if they had a product I wanted. But my couple of interactions with their "consultants" were a big turn off.
Without inquiring about my background, I was treated to a round of "audiophile 101" by the first one. I made the mistake of listing my current components and cables while I was still building my system. I then received a lecture about how my current cables were "a mess" and I needed to replace them with a full loom of a brand I had already mentioned I didn't care for. I eventually realized he was upset because the cables I had and liked were from Transparent Audio and they don't sell those.
When I explained that I liked most of the cables I had, he told be he couldn't help me if I wasn't "open minded", meaning buying a brand they sell. No pretense of actually helping me find the right cable for my system. It was a heavy handed, insulting interaction.
