SONOS Connect (ZP90) - which AMP and Speakers
: 
I have recently purchased a SONOS connect and connected it to a NAD C326 BEE AMP and Monitor Audio BX1's. The Speakers blew up (not impressed) and I have decided I want an upgraded AMP. I have a budget of £800 for both items (I have sold the NAD amp) and I am really interested in getting the best quality sound for this price. I am considering the Arcaydis DM1's with a Rega Brio R, but i am wonering if anyone else has any other suggestions or ideas. The AMP will only be connected to the SONOS (and perhaps a CD player) so it does not need lots of functions/inputs, just the best quality sound I can get. The speakers are wall mounted and need to be no more than Height 31cm, Depth 24cm and width of 20cm. Your help will be most appreciated. Thanks.

Based on this brief, I would suggest a second hand pair of AVI ADM9* active speakers (where the asterisk stands for any of the variants). These are a self contained pair of active speakers with built in DAC and pre-amp, so you'd just need to connect your Sonos to them with an optical cable. In my opinion and experience this would get you the best possible sound for your money.
Many other people will share my opinion. Many will not. For some reason, and with the blame probably lying partially in both camps, any thread where AVIs get recommended tends to degenerate into a slanging match. If that happens then I apologise for lighting the touch paper and I hope you get lots of useful suggestions to try before that happens.
Thanks for that Dan but I already have speaker cables pre wired into the extension I built, so it really needs to be an amp/speaker option to avoid running cables or power leads.

Just a thought. As you don't need other inputs (maybe CD) perhaps you could run the Sonos straight to a power amp rather than through a preamp or integrated. I'm not technical enough to know if this is ok.
Another worthwhile consideration is a int amp with digital input. There will be spares for your CDP.
