tranz Posted May 20, 2014 Share Posted May 20, 2014 Alex C. Have you any thoughts on why the BlueJeans/Belden Cat6a sounded better? I don't doubt that your findings were correct. Alex K Alex's finding might be different, but from my testing it was 3 main things: 1. Construction quality, especially at the connector ends 2. Gauge - quite often this is either not provided or frankly dishonest since there is no oversight or penalty 3. Shielding Link to comment
sandyk Posted May 20, 2014 Share Posted May 20, 2014 1. Construction quality, especially at the connector ends Hi Tranz That point rang a bell with me, as I like to rip music with the patch lead from the PC to the Broadband Modem unplugged. Sometimes it can be very difficult getting the damn thing working again, despite numerous power refreshes of the modem as per fault finding recommendations. I was really close to tearing out my remaining hair yesterday after doing this over a period of a couple of hours. Eventually, with the 2nd cable tried, it worked again for a few minutes, then the connection was lost. In desperation I then tried a 3rd (and last) patch cable and it came up straight away and has been rock solid since. My Optus home page also appears to be coming up more quickly since then. Perhaps I should get a new spare 1M long patch cable ? Regards Alex How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area.

Superdad Posted May 22, 2014 Author Share Posted May 22, 2014 Alex C. Have you any thoughts on why the BlueJeans/Belden Cat6a sounded better? Alex K Well, there are two particularly interesting technical features of the Belden 10GX-series cable that BlueJeans uses for their Cat6 (unshielded) and Cat6a (shielded). One is the bonded-pair wires, the other is a method of creating a conductor lay--using an extra filler cord--the helps randomize crosstalk. I extracted 2 pages from different Belden docs which illustrate and discuss these techniques: These wire companies are not investing the money creating these cables based on whims or speculative science. They are pushing the envelope of measurable speed and performance. As for why the byproduct is audibly better SQ on a 25-ft. computer-to-computer run for realtime music data streaming is beyond me. But compared with 4 other brand new cables I put it up against (one of the worst was even supposedly Cat7--though no such standard exists--but I think it used copper-clad aluminum wire), it was easy to tell how much better the BlueJeans/Belden was. BTW, months ago I also bought a 25-ft. BlueJeans/Belden Cat6 (unshielded) to compare against the shielded one, but have been too busy to try it (apologies to Cornell77 and others who have been waiting to for me to report on that comparison).

sandyk Posted May 22, 2014 Share Posted May 22, 2014 Alex C Thanks for the reply. Let's hope that copper clad aluminium wire doesn't become more common too! Alex K.
