Refurbished Bluesound Vault 2

Some of these units may have been returned to the dealer by customers during  the trial period. Then given a clean bill of health for resale.

Agree that some Node 2 were returned NIB by dealers in exchange for the newer model.

2.5 or 5 doesn't really make any difference for audio . . . doesn't need that much bandwidth

The device may operate better on 5gHz due to less traffic; less dropouts, less skips.
Most wireless devices around the home/work are using 2.5gHz. It's connectivity, not audio quality. 

Faster transfer rates helps with issues of skipping/pops, etc.

Just added my Refurbished Vault II to my system and so far very happy. Not sure what refurbish means but all seems there and the price was great. 

First hooked it up directly using its own DAC using WyWires Silver IC’s to preamp and not bad. I’m sure with a little burn in things will improve.

Moved over to the DAC in my Cambridge 851C using a Nordost Siver Shadow cable and no comparison. As expected the Cambridge DAC is much better and you don’t have to concentrate on it; it’s there.

Not sure I have it up and running all there as I’m not seeing what the Bluesound App does, so at the moment I have to control what I’m doing thru the Spotify App. Will load Tidal next; already had Spotify Premium for the car so started with that. If Tidal is really that much better I’ll be very happy. I ripped a CD and no idea how to access it as the Bluesound App just hangs when I try to add a player. Just got it up and playing so I’m sure I’ll figure it out.
