Hello Soundhero,
Like you I've bought a Bluesound Vault 2 recently (in early February 2016)
CD ripping works fine in the first month and I've successfully ripped approximately 800 CDs without any issues (less than 1%).
But, like it's happened to you, since a few days now, I've encountered many problems with ripping my CDs.
I've got a lot of aborted Rip (uncompleted) of my Vault 2 simply reject my CDs without ripping at all.
My CDs are, for most of them, like new and without any scratches or damages on their surface.
Also, I've checked with different kind of CDs (used, still new & never opened...) and my ripping problems are still there...
Also, like you, I've double checked by playing the CDs on different audio CD players or computers CD-rom players, and they've all played without any problems at all.
I think I've got some kind of hardware issue with my Vault 2 and I'm going to contact the store where I've bought it to try to get a replacement unit, like you did.
If I'm right, you've received and used your second Vault 2 for almost 1 month now isn't it ?
It seems that everything works fine again for you with this new one (like the previous unit at the beginning), but I'd like to know if it's still the case and if you've ripped as many CDs with the new Vault 2 unit as you did with the first one before it begins to have issues ?
My point is, even if Bluesound accept to exchange the default Vault 2 unit(s), maybe the issues encountered will reappear after a while like it did before...?
I've got nearly 6000 CDs (or maybe a little more as I didn't recount all of them for some times now) and so far, I've successfully ripped less than 15% before issues with Vault 2 begins.
I don't want to be pessimistic, but I'm afraid that, even if I've got a new Vault 2, the ripping problems will appear again after ripping a few hundreds more CDs
So, please, could you share with me your experience and opinion about your second Vault 2, and how does it works since you've got it back ?
Thanks in advance for your answer !
