What External DAC pairs best with Audio Research Equipment?


I currently am running AR Ref 210 monoblock amps and AR Ref 5 SE preamp with a Teac N701 streamer/DAC with AudioVector QR 7 speakers. Was considering buying an external DAC. Here are the 3 I was considering anyone out there ever pair any of these DACs with Audio Research gear? If so how did it sound? Thanks 

 Audio Research DAC 9

Weiss 204 Mark 2 DAC

Hegel N50 Raven DAC

The DAC 9 is almost 10 years old and DACs have improved a lot since then. I also don't think DAC/linestage matching is particularly difficult, so my approach is/was to get the best DAC I felt would be the best fit for me in its own right, within my budget.

I have a Mola Mola Tambaqui feeding into an ARC Ref 10 linestage. It's a pretty fantastic combination.

I’ve A/b’ed myTopping d90III Sabre dac against the Hegel.   It compares very favorably and is more towards the detail goal stated with similar excellent soundstage so that might be worth a try and save some $$$s to boot. You can hear every detail in a recording including incredible micro detail with instruments in good quality recordings. 

given the generally understood excellent tonal, timbral  and imaging traits of top arc gear, i would think that modern clear, open, very liquid but fast sounding dacs such as the following would synergize well (these from personal ownership experience):

weiss

gustard r2r, for a lower cost option

better chords (qutest and up)

msb

bricasti m1

Thanks all!  great answers! I think I’m gonna give the Weiss 204 Mark 2 a shot I’ll let u know how it sounds when set up & lived with 😂 

I am running a Linn Klimax DSM/3 Organik direct (balanced) into a Ref 75 SE. This combo is exquisite, an extremely low noise floor, very black background with amazing air and separation. Source is Qobuz and a NAS full of FLAC’s from CD’s and LP’s.
