I've had a Apple Airport Express(firmware 7.6) for Christmas. I have it plugged in via optical Sony STR-DH820 with B&W 601 S3 speakers with Apple lossless music on my MacBook Pro.
Im reading on here people buying dedicated DACs. Is there any point for me to do this? as I've connected it directly to amp via optical.
Also I have the express connected via wireless. Would I get better quality if I plug it in via Ethernet cable? My talk talk router is upstairs and the hi fi downstairs in the lounge. so I'd have to buy a Ethernet homeplug to have a wired connection.
