Default Gotham interconnect cables, speaker cables and coaxial cable

Hello,
We would like to introduce Gotham audio cables including interconnect cables, speaker cables and coaxial digital cable. Gotham is one of the most famous professional audio cable manufacturers in the world. We selected some models of audio cables from the wide range of Gotham cables. We selected connectors and matched the cables to achieve high performance on sound quality. All the cables we introduce here are uniquely matched, soldered, assembled and completed by Twin Audio. We keep the cables with high quality and low price.

Gotham Interconnect Cable 11001:
Gotham 11001 GAC-4/1 "Star-Quad" cables are the most advanced microphone cables presently available. We have combined an ultraflexible PVC-jacket, low capacitive PE insulation, "double Reussen shielding" and quad (4-conductor) construction for a truly professional cable at an affordable price. The "Star-Quad" concept is known and recommended where the RF-rejection is the most important factor and where very long cable runs are needed. As we use each 2 conductors for low and high signal, we reduce the signal loss by 50% and due to the offset of the incoming RF-signal by the way the 4 conductors are twisted, the RF-rejection is over 130dB (25 kHz). The exclusive double shielding does its part of these features as well.
Conductor resistance:< 125 Ohm/km
Noise attenuation: 130 dB
Characteristic impedance: 180 Ohm

We matched Gotham 11001 with Yongsheng YS-373 RCA interconnect plug (produced by Neutrik, China). The sound character is balanced, musical and neutral.
Price: USD49/pair (1.5m) + shipping cost

★The KIT of Gotham 11001 cable x1.5m and Yongsheng YS-373 RCA plug x4 is USD29/set + shipping cost. You can diy your interconnect cables at the extremely low cost.

Sounds fairly scientific. But why would anyone even think of using unbalanced connections for that run length?

More to the point, starquad on RCA?

To get any benifit you need a differential input, and the stuff is only really a win in a **NASTY** electromagnetic environment (Think TV studio or theatre with many, many KW of phase controlled lighting and stage machinery).
I have several km of the Canford version for exactly this use, but dont really see any possible advantage in a 1.5m unbalanced hookup across the back of my hifi.

Sorry, the description is made up of sciency sounding words, but contains little real science.

That 50% figure is especially dubious.

Regards, Dan.

Didn't impress me either.

StarQuad has definite advantages if used in a balanced interconnect when used in a high interference area. But those advantages just don't exist when use in an RCA unbalanced interconnect.

Should have looked for the 'balanced, musical and neutral' non technical terminology - that's certainly not scientific at all...

Also, there are no 'low' and 'high' signals in an unbalanced connection. Sounds like misinterpreted and misused science...

Gotham 11001 GAC-4/1 can apply to not only unbalanced RCA interconnect cable and balanced XLR interconnect cable.

While countless different cables can be used for RCA interconnects, it doesn't mean that most are good choices for this application. This cable is not a good choice for a RCA interconnect.

I wonder what this strange verbiage from the Gotham catalog really means?
As we use each 2 conductors for low and high signal, we reduce the signal loss by 50% and due to the offset of the incoming RF-signal by the way the 4 conductors are twisted, the RF-rejection is over 130dB (25 kHz).

Well starquad when used properly is a well known and very effective way to reduce inductive pickup from sources close to the balanced line (say a Dimmer output cable or VFD cable happening to cross the mic line), basically it makes the effective centre of the two legs lie at the same point relative the the source of the interference so ensuring equal coupling to the two legs.

The cost is of course twice the capacitance to screen, but with a low Z source and high Z load, that is not a big deal and in any case is nothing that turning up the top end a few dB cannot fix even if it is an issue.

I am sure you can make a couple of phono leads out of more or less any cable but doing so with this one largely defeats the advantages of starquad as a means to move audio around (It will probably work fine, but it does not play to the (real) advantages of the cable in its intended use).

Gotham 11001 is very well-known in use as RCA interconnects in Hong Kong and Taiwan.

Don't know what the Gotham catalogue want to present to u. Anyway, we have been using for years with good comments over here. It is known as with clear high-range with detail resolution and good dynamics. TRY IT and you may not doubt it anymore!

We used to connect 2 conductors for signal and 2 for ground, with sheilding only connect to the source side.
