This could be a long list
Meridian G08 - slow, boring, lacking in dynamics, everything played through it has the same glossed over signature
AKG K701 - sterile and lifeless, they are also way off the mark tonally
Audio Technica W5000 - hollow sounding and a nearly non-existant midrange
Sony R10 - artificial soundstage, lacking bass and an at times overly aggressive treble
Sony SA5000 - these are so uninvolving and bright it's almost impressive
Sony Qualia - these do have some strengths, sound staging and detail being the main ones but don't sound natural at all. instrument attack and decay is way too fast and tonality is almost completely wrong
Ray Samuels Raptor - can't drive low impedance phones at all, every time i've heard a grado or low imp AT out of the raptor they always have a muddy sounding midbass/bass and totally lack extension
Ray Samuels HR2 - highly colored, gives everything an overly rich tonality
Ray Samuels Tomahawk - phones sound better straight out of an ipod compared to this thing
Ray Samuels Predator - pretty awful as a dac, veiled, and no extension at all
Grado GS1000 - these are possibly the brightest headphones ever made and have about as much midrange as the dt770s do
Do we want to include speakers in this thread as well? My list gets even longer then
