coax for interconnects

[Svend N]

There's more than one version of Gotham GAC-2. And there is GAC-3 and GAC-4 to consider as well.

Quite correct Barry. The differences seem to be in the shielding and insulation. As mentioned, I used GAC-2 V1, p/n 10421: https://gothamcables.com/en/gothamca...og/10421gac2v1

well ive just bought these 2 types of cable to have a play.

Good one Jamie. It will be interesting to hear your impressions of the two.

The twisted pair one is curious, in that it seems that one conductor has 7 x 0.1mm strands, and the second has 21 x 0.1mm strands. I've not seen that before. You'll have to pay attention to which is supply and which is return. And how do you plan to solder the shield? Most layups have the shield joined with the return conductor at the source end, and the shield is cut short (not joined) at the preamp/amp end. At least that's how I learned to do it; I think others here do the same(?)

Best of luck with the project.

cheers svend,
i went with that one because j7 uses it for tonearm cable,i had my zeta rewired a while back and always like the sound.
yep i'll use the shield connected at the source end only.

Good one Jamie. I'll have to keep that stuff in mind for when I build up a phono cable. I was thinking of using some Mogami 2534 that I have on hand, but am open to other options. Thanks for that!

Had both.

The LoCap stuff is the only Van Damme cable I've ever liked. It's got a lot of quality, unfortunately I found the top end a bit too hot for my taste. It's also a right bitch to get in any RCAs other than the MSAUDIO ones or those of similar design for large diameter cables.

The other one I've used as Interconnects and tonearm cable. Does a reasonable job but the bass was flabby and under controlled.

Obviously these are just my experiences and yours may differ. Fair play for having a go

cheers, it's interesting that a cable can totally change the characteristics of a speaker driver.so many variables,did you try to compensate with speaker position ?

No mate, no speaker shuffling. Whatever I use has to be right where the speakers are.

ive just been reading up on interconnects,from what ive learnt the best cable for unbalanced use is coax.

Just out of interest - what do you mean by 'coax' ?
I automatically think of aerial/cable TV connector lead - which seems like an impossible wrestle with any RCA connector - or alternatively the 75ohm stuff that's used for SPDIF connection (which I have tried as analogue cable)

[Svend N]

Mike, coax is a single central conductor surrounded by insulation and then a shield of some kind (either spiral wrap or braided). The centre conductor carries the signal and is soldered to the centre pin of the RCA plug. The shield is unwrapped for a short length, then gathered together and twisted to form a single "rope" of wire; this is then soldered to the negative shell of the RCA and serves as the return conductor. So you are quite right, the cable is the same basic layup as that for TV lead.

Hope this makes sense...
