@leemaze, Sorry for not updating this thread, I usually do.
I upgraded to a used Audio Note DAC2.1 Signature, it's a NOS ladder dac. I decided to stop trying to put band-aids on a budget DAC. The AN has transformed my system, it sounds wonderful. It's very well built with a huge PS, tube rectification, tube gain-stage, and in-house dac chips. It's also possible that I prefer the sonics of a well executed NOS dac.
Regarding the iPurifier, I tried it on both DAC's and w/o an external LPS it did not influence the SQ. I still have it and may be able to use it for it's optical capability into the new Dac.
Thanks for asking,
Jim
