Volume Control for Sonos

[dansiop]

I am going to get a Sonos ZP120 and run 2 pairs of speaker from it, one pair in to the bedroom and one pair in to the bathroom. I want to be able to control the volume or turn on/off speakers in each room and was told that this is possible with one of these Nile Volume Control Units , however when I look on the internet to buy this product I only get US sites. I cant seem to find it in the UK.

I have tried looking for simular products in the UK and only found this: It looks basically exaclty the same however the main difference is that this product only Controls systems up to 50 watts RMS (100 watt peak) where as the Niles Controls systems up to 100 watts (200 watt peak)

Ive checked the Sonos ZP120 specifications and it shows:

Rated output: 110W RMS (2x55W continuous average power into 8 ohms, THD+N<0.02%)*

Basically I havent got a clue which one to get and was wondering if someone could point me in the right direction if they know.

Thanks

Dan
