Long RCA or long speaker cables

Thanks sir...well noted. But I must admit I did get confused. Should I use coxail digital cables instead of RCA cables to avoid the gremlins. I probably have one coax cable at the moment.. Thus asking 

The Mogami, Newlash is two sets of twisted pairs with an outer braided shield which can be grounded aswell.

After my recent tests with the Mogami 2543 I'd go for long RCA - at £6 per stereo metre is a bargain 

Would agree, star quad cables are perfect for long runs, currently using six metre star quads with active speaker with excellent results.

I've three runs of star quad now running over the top of my 7400KVa isolation transformer with absolutely no detectable RF pickup and the system sounding far cleaner than before 😁

I’d be cautious about doing away with all the connections.  Are there any sealed box drivers, because they won’t like have extra ventilation?

There was also a similar question recently...

Iam back sir.:)

The mid range and tweeters are in their sealed boxes. But I will use silicon sealant at the penetration from the drilled binding posts, to ensure a air right seal.

@MF 1000 And @wHIZZY...I've never heard of star quad ever. Is it a particular lay of cables sir.

This explains how Starquad cables differ from standard XLR cables.

I use these and they are fantastic value and superb build quality, they are also custom made to order .

RCA digital coax cable is just a sub-set of RCA interconnect cables. Many if not most RCA interconnect cables will work just fine as digital cables. While RCA digital coax cable have a 75 Ohm requirement, it turns out that most analog coax cables also meet the 75 Ohm requirement because of manufacturing convenience.

Star-Quad is a type of XLR balanced interconnect cables that is used by pro-audio in harsh interference conditions. These conditions are seldom encountered in home hi-fi setups.

Star-Quad is far from the best choice for a RCA analog interconnect cable.

RCA cables are shielded by design - the outer coaxial conductor is the shield.........................................  You'll know soon enough if you have interference or hum ... not likely over a 1.5m run unless something is very wrong.

Well chosen RCA interconnects are a shielded coax cable. But not audiophile RCA interconnects are of this construction.

Well in my experience in my system feeding my Beolab 9 speakers they work superbly well.  I also use them as 1m interconnects and am well pleased with the results. Like most things they may not suit all situations or systems but in my case they work well.

Of course they work just fine, they are a robust, well constructed cable. But it's not a cables that others should go to extra effort to obtain. There are better, less expensive coax cables available from lots of vendors.

And to put a RCA connector on a cable that was designed for an XLR connector, will not be an easy task for many.

It was hardly a Herculean task or one requiring degree level electronics

I use 6m cables to feed my active Beolab 9 speakers, utilising RCA plugs at the preamp and din plugs at the speakers. I originally had a problem with a low level hum at the speakers which was still present when using official B&O cables and coax cables made up for me by a specialist company recommended my my B&O dealer. Tried several preamps with no success but since changing to to quad star cables the hum has been eliminated. I have also talked to another active speaker user who had a similar problem who cured it using quad star cables, so they are definitely suitable in some domestic situations. Out of interest what personal experience do you have that indicates otherwise.

Also bear in mind not all 'hum' is totally audible ....in that I mean my experience so far in running a star quad interconnect (with grounded screen at the preamp end) between my valve pre and the DCX units is that it has reduced background hiss i.e high frequency 'hum'.

I chose to use star quad in that if it was designed to cope with high frequency interference environments then, although it might be viewed as overkill, it would not struggle in my home etc.
