New User - Naim 1st Gen Muso - I don't get it!

I’m using the QB in quite a small room so it’s nice to have something compact. I can try connecting via AirPlay to see if there is any noticable difference. I reckon the QB2 would be a great solution but not sure I can justify the extra outlay. The QB works fine and sounds nice, I primarily wanted to check if I could be using it better.
