No mention of DACs, though... 

DACs are not specific to the headphone hobby, and by and large aren't targeted specifically to the headphone community.

Fair point, hadn't thought of it that way.  I definitely think there are starting to be more products aimed at the headphone demographic, though.  Serving as a couple examples are portable DACs (Leckerton, FiiO, ODAC), or Schiit's products.

+1 for Leckerton

I like anyone who documents their gear's performance and I've got plenty of praise for my UHA-4.

Say Marv, are you interested in having me point to this .pdf from InnerFidelity.  I think it's an excellent viewpoint and think readers would benefit from being aware of it.  Don't know if you want the traffic (noise) though, maybe a version of the .pdf without the Changstar URL on it would work. Or mebbe you do want the traffic.  Anyway, it's good stuff that I wouldn't necessarily want InnerFidelity to write, but got no problems passing it on as another viewpoint from within the hobby. Lemme know.

What I see:
It's decidedly bleaker than IF's bent.  While Tyll does occasionally review something he considers a clunker, most of the stuff he likes.  The PDF has the "most stuff is junk" feel to it.  Can't be good for Sponsorship either if presented as direct IF content.
