Hi Brian.
Which way do you make them? Do you make them so the cable reads (as in that's printed on the cable) away from the source so the shield attached at the source end?

Which is why it is a fallacy to state that end where the shield of a so-called semi-balanced cable joins the signal return conductor, should be at the source end. It should be connected to the point of lowest electrical potential in the system, that is the mains earth. If the source is double insulated (and is thus connected to the mains supply with a two-core cable), the case, chassis and signal return will not necessarily be at earth potential. In these conditions the cable needs to be reversed (semi-balanced cables are directional due to their non-symmetric construction) with the junction of the screen/shield and the signal return connected to the preamplifier.
Usually and in practice, it will make no audible difference but in some systems it might. It is one of the reasons why I dislike semi-balanced cables. Either stick to true coaxial cables or use fully balanced types.

Hi Joe , the shield is not connected at either end so it doesn't really matter which way round you connect the cable . I use mine ( very successfully ) with the writing direction going away from the source . However it won't do any harm to try the cables both ways as you may prefer them going in one particular direction . I think Marco prefers his with the writing direction going towards the source. I'm sure he'll be along soon to confirm his preference .
I tried the cable with and without the shield connected at the source end and preferred the SQ without the shield connected at all.

Back when I used ATC actives, I never thought to completely remove the shield at both ends. However, I remember with the well earthed AVI preamp, that connecting the shield at this end was sonically preferable (I imagined I could hear a difference and that it was repeatable ). The only excuse I can muster was that the shield pin on the ATC's was coupled to ground via a 47 ohm resistor, so not the purest route?
I think pro convention has the shield lifted at one end or another, but it's academic and I think it's whatever suits you best - as stated so well above

It was the end of May that the info about the screen on SSC was discussed/publicised, not a few weeks ago.
This was after I had already soldered up my MC5000 without the shield connected. I took the plug off my SSC just to have a look, and I have to say it's well soldered and very neatly done. I was just surprised to see the shield left floating, just as I had done.
By the way, not connecting a shield is not an "invention", mine came about through laziness just to see how the basic cable sounded.

I'm John.
In environments where emi/rfi is not an issue, un-shielded cables can sound better than their shielded counterparts. I live in a noisy environment where fully shielded coaxial or pseudo balanced terminations are a must unfortunately.
I have a simple test to find out if I need shielded cables or not for my listening environment. I connect both types of interconnects, shielded and un-shielded, at preamp input only and gradually increase volume. In my setup, there's absolute silence without any hiss / background noise/ hum with shielded cables at near max volume, but when I use un-shielded cables like DNM, Nordost Red Dawn / SPM, and Klotz MC5000 with floating shield, there's significant amount of hiss / noise / hum audible from halfway volume, about a foot away from the speakers.
