Ethernet patch cable 5e with cat 6e

As noted, it is up to you to decide whether or not you can hear (or see) a difference between Cat 5 and 6. Unlike the dynamic range for perceived volume where you need headroom above the average playback volume for peaks, the streaming signal doesn't exhibit that trait. If you are watching a 4K video streaming at 25 Mbps, you don't need another 50% or 100% for headroom.  25 Mbps is the max. 

If you want to play 192K/24 music, the max stream rate will be under 5 Mbps. With a 100 Mbps connection, you'll be 20 times that. Not sure why one would need more if that is all you're doing. My two cents is, if there is a sonic issue, it has more to do with EMF/RFI than speed. 

The really high speed connections are great when you are transferring big files and want them to download or upload as quickly as possible, but that's not a real-time playback issue. And, as noted before, higher speeds can be nice when you have a lot of people in the household online at the same time, each doing their own thing. Who else is going to be using your particular run of Cat cable? 

As noted, the main thing you are losing is shielding. If you have a highly resolving system and streamer that is sensitive to noise, it could make a difference. Trying a full length Cat 6 will give you your answer. Blue Jeans will make you any length at relatively low cost. 

Yes I have a highly resolving system.  So using 6E is much more advantageous to use versus any lesser Cable due to shielding.

Isn't it all about the shielding at this point? A lowly cat 5 probably has all the capacity you need but it's all about the noise impacting sound, either for streaming movies or hi-fi.  Is all that a good interpretation?

Thanks, Great comments

I would like to hear from people who have actually compared the two types, to see if the shielding makes any notable difference, rather than speculation.

@peter_s -- regardless of what other people hear, or think they hear, it is always going to be up to an individual user as to whether something like this makes a difference or not in their system. 

And, one other thought not mentioned previously, in this particular case, the extra expense to run an all-6e cable is virtually nothing compared to what is often spent on stereo equipment. Unless, of course, one is devoted to finding a super-exclusive audiophile Cat-6e cable. But that's a whole 'nother topic...
