Why is the PA2V2 there? Gary (the builder) is running a really small-time business so his asking price is about as low as he can make it, surely? <br />Also: easy to find secondhand units.
Quick update, we're working on this poll. JDS isnt interested in offering the C5 and we're skeptical that V-Moda will agree to offer their newest product for a group buy but we're working on it anyway.
Fiio is a good option, we've got access to most anything in their product line so the more Fiio the merrier.
