Are my CAT5 and router my weak link?

...I saw CAT 7 on Amazon. I tried a piece or two. Drat it sounded better.

This comment made me buy some CAT 7. Today I changed the 50 foot run between my computer and my ethernet switch. I replaced shielded CAT 6 with CAT 7.

To begin with, it improved my internet speed by about 3Mbps. Theory? Maybe...

Better shielding = less RFI/EMI = fewer errors = fewer resends = faster speed.

Also, it sounds better. More resolution. More relaxed at high volume. Too audible to be placebo, IMO. Maybe...

Better shielding = less RFI/EMI = ??? = less jitter.

Don't know what "???" is.

???=less digital cable and system noise since they both produce jitter. Also less analog cables pickup. One thing to remember is that speed of Ethernet cable directly doesn't effect anything since data has no timing. Effect is indirect by radiating noise.

Thanks for the responses so far. It has made for interesting reading. I have my computer hard drive connected to the router via cat6 cable, non shielded. That run is about 10 feet. Then I have a 50 foot run, cat6 unshielded, from the router to the DAC.

It sounds like a relatively inexpensive experiment to try the shielded runs, but what about the router? I just keep thinking about all of the money I have spent for high end gear and their fancy connectors, etc. and want to know if a $120 router will be my weak link.

Thanks!

I doubt it. The physical separation between the router and the system would seem to make it very unlikely that RFI generated by the router would have any audible effects on the system. It is conceivable to me that differences in the risetimes and falltimes of the signals generated by different routers could result in VERY minor differences in noise conditions within the DAC, but I doubt that those differences would have audible consequences. Even if they did, there would be no reason to expect a more expensive router to necessarily be better in that respect, and it very conceivably could be worse.

I switched my freebie network cables over and heard a difference. One was clearly preferable to the others. So I demoed an Opal, was a sure improvement on all the freebie ones, so much so, I paid the £100 for it...

Yes maybe mad, but it was cheaper than mains cables, IC's and speaker cables I have...
