Following on from using a separate amplifier for the Brennan I have now bettered the sound and it is excellent since adding this gadget which connects up optically!
The lead that comes with the gadget a DAC to Analogue Converter is not suitable for the Brennan input, thankfully I had a lead that terminated in a 3.5mm optical plug that went into the Brennan output socket. I think this is what you will need to use the lead if interested
The output optically is very loud and hi fi clear and rocks the house! I don't even have the volume turned up on the Brennan!
Thanks to everyone who guided me to use another amplifier.
