Yes, I'm not clear on how his blinding setup works, but this sounds like the sort of activity that could easily unblind oneself.
Well that and if this device is so great that it will save music and we need to send $500 and re-purchase our entire music library from the Pono Store, then you should be able to tell the difference between it and a tablet pretty easily without 15 minutes of intense concentrated listening.
Search for "Blind Testing" on the first page: "I use a passive three-way switch to route the outputs from the three sources to a pair of headphones. ... without looking, I scramble the cables in each hand."
Can that possibly work? I would not expect cables to be perfectly indistinguishable (human touch is pretty sensitive), if only because of slight differences in tension/position/direction.
