@ErkyPerky, I have noticed/observed that the A30a seems like it prefers to ask the feeding device to connect to it (in my case, via SPDIF, the DVD player). What this means is.... I place the A30a in Standby (via the remotes Power button), turn on the DVD player, wait for the DVD player to say 'no connection', then turn on the A30a via the remotes Power button, the A30a then indicates the connection in the view panel. This only an observation (so may not be relevant) but perhaps you could try this, that is... place the A30a in Standby, connect/turn on your iPad, wait for the iPad to say 'no connection', then turn on the A30a via the remotes Power button, the A30a then indicates the connection in the view panel. Note that this may not be relevant and is only an observation but you are welcome to try this and if you try this, let us know of your experience :=)
1) Do you use the supplyed USB cable? If no, how long is the USB cable that you use?
2) It could be an issue between your Streamer and iPad (I am assumeing the connection is Wireless), although it could also be that the A30a looses it connection, or encounters a connection issue, with the iPad or visa versa (refer to point 1), couldn't it?
