Can anybody share some views about cat7 cable?

What exaclty do you want to know?

If you are interested in audio application experiences with naim gear, you will have a hard time finding anybody using it, because Cat7 plugs do not fit in RJ45 connectors.

Pinkhamster, I think you'll find Class F Ethernet cables (in consumer land known as 'Cat 7') can  be terminated with 8P8C connectors (compatible with RJ45) or TERA connectors ( which are not)

To the OP I'm sure Cat7 cables will work fine, but why bother? They really are designed for runs of 10Gbps. Naim can only reach 1% of that at best with 100Mbps.

CAT7 equipment is usually terminated with GG45 plugs/sockets. You can plug a RJ45 plug into a GG45 socket, but not vice versa. So in order to use a CAT7 cable with Naim gear it will have to be terminated with a RJ45 plug, which downgrades the whole connection to CAT6e level. So there is really no point in using CAT7 patch cables currently in a home environment.

They only make sense for permanent installations in terms of future proofing.

Well my information is that most current pre terminated Class F Ethernet cables at 10gbps are in 8P8C which is the modular Ethernet  terminator compatible with RJ45 - so given there are potentially incompatible choices, best check which terminators are on the cable when you buy. 

I just did a quick unscientific check on Google and 'RJ45' seemed to be the most popular connector for Cat7 - (which for an Ethernet plug means 8P8C - 8 pair copper)

Further I have read as of May this year  IEEE TR42.7 has now defined a new specification - referred to in some quarters as Category 8 and this will only support 8P8C connectors and so other connectors other than 8P8C (such as GC45 and TERA) used in Cat 7 will be incompatible with future cables and connectors.

Perhaps therefore Cat 7 is not a good choice for future proofing or infrastructure?

I stick with Cat 5e UTP and Cat 5e STP.

I had so much trouble with my ISP supplied router, that I set up a separate router for media. At the same time I switched all cables to CAT 7 (mac mini -> router, Uqute2 -> router, router -> modem.

Why everything sounds better, I cannot say, as I never compared just cables. I can say that I prefer music through the router to directly via toslink http://www.lifatec.com/toslink2.html from the mini.
