Streamer recommendations

you should look at the Burmester 151mk2, excellent player and streamer, preamp stage is superior over all 3 you listed and so is overall performance

I highly recommend listening before buying. dCs is very polite sounding and a bit clinical. If you like that kind of sound, great. But it leaves me unmoved.There streamer is also very dependent on the incoming signal, so hardwiring it is a must, or it sounds tinny..

A good Aurender or Lumin streamer should sound as good as your CDs or better. Since Quboz has half a million high resolution albums… those should sound better.

I really like Aurender.   I went from a Bluesound to Aurender and in a good system it is definitely worth the expense.   Build quality is over the top and support has been great the few times I've need it.   

'm still enjoying the Vault in a second system and I'm sure when it dies ill replace with a BS Icon.
