Thanks for your interest, I'm getting there slowly and your replies are really helpful.
Connectivity aside I have another problem in that 525gb of data which I have both on my Windows 10 and on a portable 1tb back up, these are mostly FLAC but also many high definition tracks
which I want to get on the B2.
These were both saved as NTFS and the B2 can only accept FAT32, any ideas on how to sort that will be most welcome.
Paul at Brennan suggested connecting the B2 to the Kef's using the aux socket which I'll try when I can.
The sound from the Kef's from Sky Arts concerts is amazing, takes me back to the days when I was using Quad amps and Quad electrostatic speakers, yes, I've been doing this that long.
Thank you all.
