Quote:   I remember reading somewhere that speaker frequency response is measured 1 meter from the speaker as well.  Just a guess but I'd bet that the drivers in just about any  headphone would measure as a tweeter at 1 meter.  

That surprised me too.  That's the first headphone I heard that.

Quote: I finally got a change to test the ECR-500.  I also used the tones on this site http://www.audiocheck.net/testtones_sinebursts20-200.php because I wanted to test 20Hz as well.  Those tones seem more accurate than others I found.  They seem to match the tones you posted were others...

Unfortunately, I was snowed under at work today and didn't get a change.  It'll have to wait until Monday.

Quote: I'm teleworking today so I check it tomorrow.  It's pretty rare with any headphone to here 30Hz without turning up the volume.  I tend to listen at low levels.

Quote: I haven't run test tones through them but the Sony ECR-500 have plenty of bass.  I use mine daily at work driven by a Kyocera R-851.

I doubt the HE-6 would be driven well out of the headphone jack.  One really pushed my 65W Realistic STA-2200.  With 15W - 20W, you'd probably have to run them off the speaker taps.

I've had mine for quite a while now and I've had no problems at all. 

I cut small pieces of carpet tape and essentially made a ring on the baffle.  It's OK, but I really need something a little better.  The tape I used isn't very good and the pads don't really stay on.  I generally have to readjust them every time I listen and they frequently fall off as I pick up...

Quote:   I didn't send him a Sextett but I did send 4 orthos when he sent a request for them.  I let him keep them for a while too so he could listen to them.  I sent him my Fostex T30 which is my favorite headphone and pretty much irreplaceable because it's so rare.  In comparison...

It's been my experience that most amps have way too much gain, even for moderately hard to drive headphones like vintage orthos.  With most amps I've tried, I'm lucky if I get the volume knob past 8 o'clock, even if there is a low gain setting.  Even portable amps supposedly designed for low...

You guys do realize this is a 4 year old thread. 

That's what I felt like saying, but I only own normal bias Stax.  I find it hard to believe that they can sound good at under half the bias voltage.
