I always got my audio kit from Richer Sounds. very reasonably priced if you ask me, and this time of year will have some good deals on.
I will be going down the Denon and KEF route again. really loved my set up I had in the UK. Its also worth making sure that the AVR you get has Airplay built in
I had the KEF Egg speakers, they were awesome, I am sure Chris`i will be along to confirm as he has them now
