Hi can someone advise me on the lightest, thinest and most flexible 110 ohm cable I can get to make some analogue or digital cable? I prefer to use 100 ohm cables even on analogue signal. The cable has to be very thin and flexible.
Thanks!

These are all 110 ohm digital cables, though I haven't worked with any of them (just the thicker DA202 Canare version).
Canare DA202-AT
Belden 1800B (or the dual/siamese version 1802B for mic cable pairs)
Gepco DS401 (or the dual/siamese version DS401D for mic cable pairs)
I'd recently been reading that digital audio (110 ohm) cable is actually better for analog signals due to their low capacitance. So I had been toying with the idea of 110 ohm cable for analog, but I hadn't thought about using 110 ohm cable for 75 ohm spdif digital audio. Does the 110 ohm digi cable work fine for 75 ohm digi signals, assuming very short runs of only a couple feet?

I've used the Gepco. This is really nice cable. It is probably more suitable for light use (or permanent installation), though, since it has a foil shield. I imagine this will break if you flex it a lot. It is less flexible than a braid too. If you're looking for twinned cable for heavy use, see Canare 3106. This stuff is thicker, but it is more flexible/durable.
I love the twinned cable. Once you use this, you won't go back to pairs of cables. This stuff is great for what we do. It also makes great interconnects, balanced and unbalanced.
Oh yeah, if you want the Gepco, contact Fritz at H.A.V.E. audio. I think it is 33cents/foot or something. Canare 3106 is approx 1$/foot at Markertek.

If you get the Gepco Bittree it was a wire shielding and is 110 ohm. Pretty small diameter too.

If its only a foot or two then the resistance of the cable/connectors isn't so important and pretty much anything will work. Do you think the yellow RCA on those ultra-cheap video/stereo cables that come with DVD players and cameras is any different or connected to different wire than the red/black ones?

For portable applications, I'd recommend Gepco's braided shield version,
DS601M

or for longer runs, DS401M
