Question on cable selection for Vandersteen 1

Do you mean 14/16 mm or 14 *GAUGE*? Most wire size is given in gauge, and the lower the number, the bigger the cable. So 14 ga. would have less resistance (and possibly more bass depending on a lot of other factors) than 16 ga.

What are you willing to spend on cable? There are some speaker cables specifically made for tube amps from Transparent and Audio Magic, but they're pricy.

Otherwise, I'd just get some Audioquest GBC on closeout here. You'd be hard-pressed to get better for anywhere near that money.

Alpha-Core Goertz is reported to work well with Vandersteen. They're reasonably priced, and Alpha-Core offers a generous free trial period.

I'm using Anti-Cables on my Vandersteen 5A's with great success. Give them a try, you'll be surprised. They have a money back satisfaction guarantee.

My Vandersteen 1C's are connected to my Rogue Audio Cronus integrated amp (EL-34 tubes) with AudioQuest Type 6+ cables, and the synergy is wonderful. Give these cables a try. You may be very happy with the sound. Happy Listening.
