what pre amp for ATC SCM 40v2 spkrs + 250.5 Pass Labs pwr amp


Hi Friends!
I'm looking for everything, more detail, larger sound stage, more low end etc. 

I'm currently using a Naim N-272 streamer dac pre, though good I'm looking for better.

I'm pondering on Schiit Yggdrasil gen 2 and Freya +, 
or
AR Ref 3  and  Yggdrasil  (Ref 5 is out of my budget).

Will be using blusound node2i as streamer. 

I'm looking for
1) general experience what works well with the SCM40v2 (as these are keepers) 
2) as well as technical advice on a matching Pre with my 250.5 (specs below)
eg. input impedance (as I've only been reading chatter about this but don't know how to utilize this data). 
I will be using all XLR since the gear above supports. 

Anyone with experience to lend?

my systems are visible on the virtual system page. The reference is an ARC REF5se preamp that while it does not meet the balanced standard that Ralph cites, make decent sound. It drives a 6 m length of Audioquest WEL cable effortlessly into Vandersteen M7 HPA amplifiers. I have used an inexpensive mogami set of XLR wire also with excellent sonic and low noise results.

I have spent more than a few hours listening to the Ayre KX-R preamp and it is an incredible bit of SS engineering. I have owned an Ayre power amp in the past and currently own and use in a recording studio an Ayre A2D converter - anything Ayre touch sounds good and is hyper well engineered.

just my two cents.

Ralph of course makes great gear also!
