I ‘ll try and get Chord to lend me a pair of 3m cables. They are only just up the road from where I live.

If successful will report my listening observations.

Does Crestron do a cat7 standard cable?

The Crestron cable meets cat 6/7 standards but is not flat.

Hi all. Thanks for all your feedback.

I have managed to borrow a pair of Chord Epic & Signature streaming cables to try, with the intention to buy either if the improvements (if any) justify the outlay.

My friends at Martin's HiFi have offered their assistance with this issue, Big thanks to them, I've never come across a better team to deal with, I await the arrival of the cables and will post my findings in the near future.

To add to Steve’s comment, I have been in contact with Chord who recommend their Signature or Sarum T cables. The latter are rather expensive!! The former are a tad expensive!!!

Perhaps more interesting to anyone following this thread, is that the chap at Chord advises me that they need to know whether any streaming cables they are building are to be used in lieu of Speakerlink, as “they are wired depending on what is being sent from each pin, for example data, power, etc”. This applies to their “higher ranges of cables”. Read into this what you may.

I will follow up with a local supplier, but also look forward to Steve’s opinions.

Cheers

Haven’t tried this myself but Cardas now makes a copper-based Cat7 cable. Cardas Clear Network

These are the cables I was on about in my earlier post, which are giving me great results in my entire Sooloos chain, from router to ID41.

Universal networks tested patch cables

Shielded series

My 2 p: great reliability for a normal price.

Steve,

These are very good sounding cables incredible price.

Better sounding for my ears as much more ridiculously expensive cables, you should try it out.

I've been doing some research on this subject and found some information that was new to me, maybe it's useful for others.

SpeakerLink is based on AES3 Annex D, which delivers a balanced digital signal over shielded twisted pair network cables, as described here.

Originally Posted By AES3 description from Library of Congress
The main body of AES3 specifies signal transmission via a single shielded twisted wire pair. Annex D, however, discusses the carriage of AES3 signals on structured wiring, e.g., the "category 5" cables associated with computer network installations, a topic that receives extended treatment in AES47, which specifies the method of carrying multiple channels of audio in linear PCM or AES3 format across an asynchronous transfer mode (ATM) network. Elaborations on audio signal transfer are the topics of AES10-2003, AES Recommended Practice for Digital Audio Engineering 8221; Serial Multichannel Audio Digital Interface (MADI) (Revision of AES10-1991), and AES50-2005: AES standard for digital audio engineering 8221; High-resolution multi-channel audio interconnection.

It appears to have broadcast industry ancestry as explained in this document by StudioHub.
Originally Posted By StudioHub+ document
A 1997 report, entitled “Review of Cables for AES/EBU Digital Audio Signals” conducted by the BBC Research and Development Department, concluded that CAT-5 shielded twisted audio pair cable “offered the highest performance of all the cables tested here.”1 Their tests included coaxial cables and special cables specifically designed for digital audio, but they preferred CAT-5 cables for their overall flexibility and applicability in mixed data applications and consistent performance.

I looked for cables made specifically for the Pro/Broadcast market. From what I can tell, the focus there is mostly on durability ("tour grade" "entertainment grade", "tactical" etc), like this one. Unless you find yourself pulling on your SpeakerLink cables a lot of stomping on them with work boots, I'm not sure they make sense. The XLR-like shielded connectors with RJ-45 plug inside look interesting but they won't fit in any M gear.

As SpeakerLink is one of the few, if not only, Pro audio applications of AES3 in consumer audio, I have not come across consumer brands that make products targeting this market: high end CAT cables for AES3 digital audio. The big brands do seem to have discovered a market for high end CAT cables for computer audio and networking in general. Presumably these cables from AQ, WireWorld, Cardas etc. are constructed with higher-grade materials than your run of the mill CAT cables but it doesn't take a lot of time on Google to find a teardown of an expensive cable that doesn't look very favorable. Also, I'm not sure whether they are all measured to the extent Belden cables are, for example or which measurements are the most important.

There are reports, including on this forum, that changing the brand or type of CAT cable influences the sound. I'm curious what factors influence the sound most. Wire gauge, wire contruction (stranded vs solid), wire material, (copper, silver, silver plated copper, etc). Connector quality, shielding, conformity to spec (cat5/6/7, etc) and whether it's possible to find cables that have the right combinations of these qualities that don't cost $1000/meter.

I found a few cables that fit the bill but I haven't tried them yet. For example, this Gold-plated Copper CAT7 cable with Telegärtner connectors at EUR 69 for 2m.

The above are observations and notes based on the assumption that changing cables for SpeakerLink connections makes a difference at all and I'm not looking to debate that. I simply wanted to report what I found.

Here's an option from Ohio. I've used these to good effect and think K. Swanson has, too
