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?

To this end, its really helpful if the output impedance be constant across the band rather than rising at lower frequencies


Would the output impedance of the preamp be static across the band if by design it's not dependent upon feedback?

@atmasphere  Ah gotcha.  So a transformer-coupled design would be more desirable on this front?  I appreciate the education that your posts always bring.

I've been really pleased with how well my VAC Ren MKV preamp pairs with my Pass XA30.8 amp, and hence picked Ralph's brain a bit about whether the preamp design lends itself towards good compatibility - including excellent and tight bass extension.  From the sounds of it, the VAC's transformer- coupled Class A1 balanced triode design is likely responsible for a large piece of the synergy.  I feel the combo is giving me a flavor of the best of SS/tube integration.
