Thanks for the reply Nick_UK - still a bit Heath Robinson as a solution, and headphones would stop the rest of us hearing the music

.
Anyway, I've decided to compromise on item 3 (we'll get an extension lead for the garden if necessary).
So it is between the AE Wifi unit or the Imp. I've just seen that the Imp is going for c£130 at Dabs, which is very favourable to the AE unit which I can't find for less than £190.
Word is that the units have similar but not identical components. Frankly, I don't like the look of either, but the AE unit looks slightly better from the photos.
Has anyone heard both? (connected to Hifi and standalone) Care to offer an opinion? I want to move fast while the Dabs offer is still open.
Thanks
