As someone else correctly pointed out, it's a not a delay caused by the amp's D2A capabilities...the sound is fractionally ahead of the visuals.

Looking at the possibility of an HDMI-RCA or -optical converter (if such a thing exists) to utlise the HDMI audio output from the player, but for the expense, it's probably easier to get hold of a top-jolly optical cable.

I'll go and have a chat with the spuds at Richer Sounds...I have a £30 voucher for them that would cover the cost.
