Best reasonably priced interface with Bluesound Vault 2

For the Bluesound Vault 2 need non-geekish recommendations for best dedicated tablet to run the thing.  I've a Naim UnitiServe with iPad which works great, but this will be for another location geographically so no sharing.  Will the Amazon Fire work?  Thanks in advance for feedback.  Ciao
I have been using the Fire HD7 tablet for a few years to operate my Node with no problems
I use an iPad.  I tried the Fire and the Android interface wasn't quite as slick but that was over a year ago and they have updated several times since then
i have a u-serve and a Powernode. The Bluesound tablet interface is terrible compared to nserve. But if you must I suggest getting another ipad.
