I have one and it's very nice.
It's a really good mid-range "just add speakers" setup. Looks good, works well.
There is no FM/AM/DAB receiver on board, but you can play internet radio via TuneIn. A lot of stations are easy to stream this way, BBC of course, but most of the commercial UK stations are easy enough too, e.g. ClassicFM, Heart, Capital, etc. and other some other stations from around the world.
If you want FM/AM/DAB you could plug in a radio into the PM7000N using RCA cables.
For streaming you use the Heos app or an app from your phone that supports UPnP/DLNA - BubbleUPnP works best for me, but mconnect is also fine. Or if you are using Spotify for streaming then it supports Spotify connect, so you just control direct from the Spotify app - very easy to recommend this amp for Spotify users.
Bluetooth and Airplay streaming both work well from your phone.
It has a lot of connections so you can plug in a record player or other sources later if you want to, and it's easy to feed your TV sound signal in via an optical cable to upgrade your TV sound experience, though it's not a surround processor or anything.
After having had it for a year now it revitalised my interest in hifi so that I have ended up wanting to upgrade a lot.
There are only 2 other things I have found that I would caution about:
1. The amount of power available is moderate - 60W per channel for 8 Ohm speakers. The B&W 607s2 speakers are fairly hard to drive, so it will depend on your space as to whether they will play cleanly at high volumes. They will certainly play loud enough, but with a more powerful amp might be a bit less troubled.
2. Not upgradable. There is no pre-out, so you cannot feed the signal directly into a power amp if you decide you later want to get more power without adding extra kit. Really this is meant to be the heart of your system, not one one piece of amp/pre-amp/streamer, etc. It doesn't give you an easy upgrade path, but it's enough system that you might be perfectly happy and never want to upgrade it.
A comment on the combination you have seen advertised - it's not really a very special deal. The Marantz is normally available for around £900 and the speakers £450, so a £100 saving, but you could likely negotiate that much discount on any amp/speaker combo in that price range.
Those speakers have moderate amount of bass, so for instrumental, vocal and unplugged music you will be astonished how good the system sounds. However if you want to play rock/heavy metal or orchestral you may be better off with a different set of speakers. The Marantz has a subwoofer output too, so you can easily add a subwoofer later.
However I would not particularly recommend that system as advertised.
Often a decent rule of thumb is that the speakers should be 50-75% of the overall cost of your system. Following that line the advertised deal is not a very well balanced system. The Speakers are only 1/3 instead of 2/3. If you are going to spend 1200 you would probably do better to spend 800 on speakers and 400 on amp/streamer.
For example I would rather have :
1. Yamaha RN602 (£450) + Q Acoustics Concept 40 (final few available) (£700) (floorstanding)
2. Yamaha RN602 (£450) + Focal Aria 906 (£800) (bookshelf)
3. Yamaha WXA50 (£380) + Klipsch RP5000-F (£850) (floorstanding)
4. Yamaha WXA50 (£380) + Klipsch RP-600M (£625) (bookshelf)
You would likely be able to negotiate a discount on these ^^ too.
You could hide a subwoofer in the corner as an addition to #2 or #4 later if you want more bass as the Yamaha has sub output. Klipsch has a £400 subwoofer for example, but they are available at many price points.
Obviously there are many combinations of systems that can be put together for £1000-£1250, the market is very competitive at that price level, and other people I'm sure might make recommendations.
