I know my player is a few years old now, originally cost me over £300.00. However, on the thought about tweaks, I have an audio alchemy dac in the box, just wondering if this would make a major improvement over the present onboard dac of the panasonic? Does anyone know what settings I would need to set on the player to use the off board dac? I would have no problem connecting it using the toslink cable I have. Bill.
