DAC help For my tube rig


Looking for some guidance/validation...
Need to add a new DAC to my Shindo Massetto/Montrachet into Devore O/96.
Current list of contenders are:
Auralic Vega (want to add the new Aries streamer too)
Ayre QB-9 DsD
Lampizator G4/L4
PS Audio Directstream

Any thoughts or experience would be much appreciated.

Thanks for all the feedback (and sorry for the delayed post, for some reason I was locked out.) Over the weekend I picked up an original Ayre QB-9, which I'll send off to be upgraded. If that doesn't do the trick then I'll explore the Lampi or AMR further.
Well that blew up in my face. Ayre tells me the waitlist for an upgrade reaches into Jan/Feb 2015... and so the search is back on.
I agree with Charles, I owned the Vega and liked it a lot, but the Lampizator Big 5 is much better albeit more $
