I have had some recent experience with some of the streamers mentioned. In my office system which I listen to more than the main one now I have a metrum acoustics adagio NOS DAC / preamp and stream into it from either a metrum ambre - which sounds very good - or direct from an innuos mini mk3 which sounds quite considerably better. You have to enable squeezebox lite in roon to do this. The only issue is that when its streaming from tidal (as oppose to from its hard drive) you get occasional drop outs which to be fair roon warns you about with squeezebox.
In my main system I have a Lumin A1 which i have had for years bypassing its own DAC streaming into a border patrol DAC. This sounds v fine too but again when I have swapped in the innuos it sounds richer, cleaner, more engaging.
It was actually Gary Dews at Border Patrol who recommended streaming direct from the Innuos to the BP DAC as apparently he does that when he demos the DAC at shows. Something to do with its linear power supply. So if I had to keep one of the three streamers Id keep the innuos.
My question would be - I love the Aurender displays but they arent roon compatible. Anyone know a streamer with such a high quality display which does roon? Auralic I guess...
Cheers
