Hi Michael
Thanks for the review.
I am an audio buddy of Ted's and I too have the Holo DAC Level 3 in my system. I am running it into a Bent TAP(thx Ted! - until I get my new pre...). I too am running the Holo in NOS mode while utilizing HQ Player. I love the ability to go back and forth between upsampling PCM to 352 or upsampling everything to DSD512(my favorite).
I tried the Singxer but ultimately preferred the Holo without it. I have also gone back and forth running SE and balanced into the Bent and finally chosen SE as my fav. Balanced was a bit "in your face" while SE allowed me to raise the volume without the fatigue factor raising it's ugly head.
Regards,
Randy
