I like the Border Patrol DAC. Sounds great. It works most of the time but occasionally it just goes silent. I can wait or kick it on with the on/off switch. When I get time I will ask the company what they think.
No I am afraid not, but if you find a good one let me know. Sorry for the late reply, I have been out of town. I do go to the Goodwill in Germantown a few times per year and have never really "scored" anything of consequence.
