Looking for a new DAC

Not sure how much "coaching" I can give re the specific DAC's you mention or sound signature.  However I am responding as I have Modwright components - LS99 preamp and PH 9 phono stage.  Like you my Modwright components are going to stay a part of my system for a long time!  My amp is a First Watt F8 and an Aurender N200 plus a Schitt Yggy LIM.  Speakers are Volti Razz.  I like the sound my system produces and know its.a combination of may factors including the tubes in my Modwright preamp.  I am enjoying the sound of my Schitt Yggy LIM but will likely be in your boat looking for a change in the next few years.  I have decided that I want to try out whatever DAC/DAC's I narrow it down to in my system since the individual components add up to my "house sound"  As a result I am going to look at vendors that have a trial policy - Mojo, Audio Mirror to name a few.  I also believe there are trusted dealers that may provide a trial DAC in the right situation.  My point being based on what I have read of your thinking above, if that your next step is to research a handful of DAC vendors that provide a trial period and narrow it down to a few.  This will enable you to further clarify your "house sound" and its specific to your overall system.  I have trouble expressing exactly what my system sounds like.  I can read reviews and listen to other systems but in 99% of the cases the overall system is different from mine.  Good luck on your journey!
