Ok, if you thought your DAC was good, you still do not know what it is capable of. Use this with your DAC and it will, most probably, change your perception towards digital music.
I am using it with Benchmark DAC1. I have Yggdrasil too but I can listen to my music on either system; the combo is comparable.
So, up for your consideration is my Audiophilleo 1 with Pure Power. This is the SE version that can do DSD too. Please refer the website for complete information. Rating 8 because there is a very small mark on one side of Pure Power battery pack (please look at the third photograph.
PayPal and shipping to US48 included.
Why I am selling it??? because I have moved over to a AoIP solution and this thing is lying idle.
I may be willing to package this together with Benchmark DAC1 USB (of course, at extra price :)). Please ask if you are interested.
