Great suggestions. The Auralic Taurus sounds very promising. I see a used one on this site for a little over my range, but might be worth a try. I checked the drop website for amps/dacs but it seems that anything that catches my interest is sold out/through and won’t be available for a few months.
There have been a few updates since I created this thread. I ended up ordering the Hifiman Ananda’s from Amazon (arriving this Friday). Of course they are three times the price of the HD6XX but I want to see if the price difference is worth it. I will A/B the two for a week or so and then make a call as to which one to keep. Supposedly, the Anandas are an easier drive, so they might work with the Naim unit.
Another option is to use the Naim as a DAC only option, and hook it up to a purpose built headphone amp like the Cavalli CTH hybrid.
