Thank you @simon g. I will certainly take a look at those.Have a look at the DAC/streamer I use, which I preferred to a Dave; the Bricasti M3MDx+N. If you're close enough to tne Lincolnshire coast, you'd be welcome to take a listen in my system at some stage. There is also a version which is a DAc/pre, without the network card. No mucking about with power supplies, either!
The Lincolnshire coast isn't a million miles away, so I may just take you up on that offer at some point 👌
