Oh no this is my main cable for my board and other unbal interconnects. XB20UB. Why can't I find it anywhere online? I used to just buy it by the foot from ebay...now I can't even find it for sale from suppliers. Where did it all go lol? It's as if it was wiped out of existence and maybe I dreamed it up. The small diameter (~ .228") is important for my Lava CX plugs. These are short hops, one foot or much less. I guess my actual question whether Canare GL6 the best substitute...
I'm in the same boat. Really like that cable - well-built, low capacitance, and reasonably priced. Canare GL6 is fine cable, but over double the capacitance if that matters for your use. I contacted Gepco and they said one of their dealers has it in stock: http://www.avad.com/ But like you I couldn't find any place to buy it online; and flipping through a few sites I didn't see anything that looked to me like a direct substitute on all features/cost...
I also have been having trouble locating it recently. I like it for its low capacitance and resistance plus it's double braid shielding which is very effective and durable.
Good news, possibly. General Cable Welcomes the Addition of AVAD as a Distributor for Gepco® Brand Products
Redco Audio now has an identical cable to the XB20UB from Lake Cable called AVB20UGC. Same dual shield, capacitance, wire AWG, etc. Lake Cable AVB20UGC Dual Braid Instrument Cable | Redco Audio
