SR-Lambda
Fit and comfort:
Feel very light on the head probably because of the weight distribution. Very comfy, the pads are the only complaint after listening for a few hours (pleather?) The cloth headpad is an improvement from the sr-404's leather. Not much clamping, no problems if I'm wearing glasses.
Not to wax too poetically about these but to say I'm extremely impressed would be about right. They are very musical with an uncanny midrange- the midrange is the closest I've heard to the Grado HP-1000. Except more detailed and more "in the room" rather than in your head. Still they sound like a pair of circumaural Grados with their forward signature. They handle rock and jazz exceptionally well. They tend to get a bit homogenized with large scale classical. They handled everything from Metallica to Neil Young, Miles Davis, Robert Cray, Ravi Shankar, etc without breaking a sweat. Depth of soundstage isn't that great, but it still goes out there a little bit. The Stax can handle open mic (single mic) recordings like no other headphone. And one of my favorite parts- the bass impact is simply sweet as hell (Radiohead's 15 Steps sounds so good same with the mfsl of Dsotm, lots of PRaT).
The not so great parts are that they don't reach very low, low basslines and piano pieces sound light. I don't like them at very, very low background listening levels since the bass loses impact. But at lower to medium levels for active listening the bass impact is perfect. And they are a bit diffuse and hazy like the Senns. Still a bit of "bite" up top but no where near as bad as the SR-404, I prefer the darker SR-007. And it kinda sucks that if I want to use them for background music I have to be sitting next to a big power amp, but they'll still be replacing my HD580 and SR-325 theres just no contest.
