7777,
The Naim is lovely. But it's also 2K and is only a stream player, it doesn't stream anything itself. It is also a single unit, so you need a second one for the other room. Oh, and you have to buy the speakers to go with it, say 500 for a decent pair.
So that's 5K for 2 rooms; and you still can't share between them without a NAS streamer.
Apart from, as a multi-zone media unit, it seems fine.

A confession.
I used to have a 8-10K Home Cinema system. Top of the line flagship amp, 10 speakers etc. Got rid of them all and now just have a Yamaha sound bar plus sub-woofer. Does me fine.
At one stage, may years ago, I had a Linn Sondek deck, Quad ELS speakers, mono 405 amps etc. Ended up with a Naim CD transport, Musical Fidelity AC3 pre and power amps, B&W Nautilus speakers.
Again, I got rid of them all. Not sure if it was my ears or my interest went. Listened to them less and less. Now I have a small Denon system in the study with a pair of Monitor Audio bookshelf speakers. Does me fine.
It goes back to what I used to tell people when I spent a fortune on Hi-Fi. Most people can tell the difference if they listen, it's just you get into diminishing returns for the amount you spend. My threshold has just reduced over the years.
Instead, I just spent 1600 quid on a new MacBook Pro 17" when my old 15" was still working.
