Help with Preamp Selection and Network player


Looking for tube preamp. I have the opportunity to purchase three different preamps around the same price.
-Primaluna Dialogue Premium
-Cary SLP-89l w/upgrades
-Luxman CL-38uc
Looking for opinions on sound comparisons and flexibility. Will be used in front of Parasound A21 feeding ATC SCM19's.
Also, narrowed down my choices for streamer/dac down to Cary DMS-600 and Naim NDX-2. 
These two units offer the ability to use my existing CD transport, HDD loaded w/music, Roon ready, and future NAS.
Any insight would be appreciated.
Thanks

NAIM for all the quirks will be in the digital business long after CARY....ai would stick w them for a fairly solid app that will only get better over time.

sort of agnostic on preamp opinions on the 3 you mention...

one advantage of the forum is the exchange of ideas and inputs FOR ALL to see and learn by....just my two cents...as opposed to advertising....
