Seeing no mention of the FLOW's duffy remote controls in Headphone Guru's review of the Aurender FLOW, I am led to believe that track forward now means track forward. Barring that, it's obvious: audiophile reviewers really only care about how something looks and sounds; more specifically, that we dig song-specific subjective analyses, which Eric Neff does pretty well.
The thing is: until audiophile reviewers get good at reviewing gear, not just sound, the gear vomited out by unscrupulous vendors will only proliferate, reaching critical mass, where shit becomes normal as long as it sounds good.
Aurender FLOW is an awesome performer, but its hardware interface is duff, and should be crapped on in CONS lists of all reliable review sites.
Disclaimer: I reckon my take on the Aurender FLOW is the best out there.
