Aurender N20 or A15

Some more background:

Update.  I auditioned a Weiss 502 for about a month.  Very fine piece of equipment that was quite frankly built better (not as flashy, but better connections and knob feel) than my McIntosh C2700 pre-amp.  I fully expected to find that the Weiss was audibly better than the C2700's DA2.  Using Roon, and setting up a zone with both the Weiss connected via ethernet and the DA2 to my PC via USB, I was able to easily accommodate A/B comparison, and then a double-blind test.  My son (who is a musician) and I both took the test and really could not tell the difference.  The rest of my system is an MC 462 and B&W 802 D4s, so you'd think it would be resolving enough to tell the tale.  The sound really is quite good, but now I am back to looking at the source because thinking about it some more, maybe that's my first constraint as my PC is in no way optimized for sound, though I do use an AQ Coffee USB cable.  So now I am back to N20 or N200 to be sure my source is as good as I can practically afford, and then try another DAC (based on another technology - maybe a PSAudio DSD MkII or the T+A DAC 200 or Holo May or second-hand dCS Bartok).  Thoughts?  Thanks All.  -Mark

Thanks everyone.  I think I am going to buy an N200 and connect it to the DA2 via coax for the short term, and audition more DACs (PSA DSD MkII, T&A DAC 200, Aqua) in the longer term.  Should I later find that the DAC has now exceeded the source then I will look at trading-up to the N20.  The digital playback realm is a microcosm of our insane hobby is it not?

Thanks @oddiofyl I don't mean to start a discussion of Roon vs Conductor, but there are some simple things about Conductor that I am looking forward to - namely rock-solid stability and paused tracks fading out and then back in when un-paused.
