I don't have T20v1 so I can't check it but wikiphonia picture showing normal T20v1, presents the headphones also without the tab on the same side.

Where does the SR-30 fall in the line up compared to the SR-40 and SR-80?

I'm getting the impression the SR-30 is a better can?

The reason I ask is that I will be receiving an ATH7 which is rumored to be a branded SR-30, but I was planning on what I thought was "upgrading" the drivers from a SR-80.

My pair has both tabs, thanks to the generosity of ourfpshero.

Near as I can tell, the SR-30 and the SR-80 arrived together, well after the SR-40, Stax's first tret.

Certainly better mechanically. The suspiciously-AT-like headset is reasonably rugged and holds everything securely in place. But it's been too long since I heard an SR-40 to say that the SR-30 was a big improvement. All I recall is being completely unimpressed by the 40.

Now-- sticking ATH-7 drivers in an SR-80 enclosure? I wouldn't hope for much, but it's one of those things that has to be tried just to see what happens.

Plan was to stick SR-80 drivers in the ATH-7 headband... Or SR-30 drivers if the SR-80s are too large.

i had only notice readable "Anniversary model Fostex" on the emblem but not seing that "not for sale" wrote on the cup..

is it wise to meter ortho driver impedance?

You can measure DCR, it's close enough to the impedance on orthos.

Having had two sets of SR-30 drivers, one set of SR-80 drivers, and seen pictures of the ATH-7 driver, my take is that the difference is in the damping.

The SR-30 has a big fiberglass cookie on the back of the driver, outside the frame. SR-80 has a smaller fiberglass cookie, also outside the frame.

The ATH-7 driver looks like the same thing, except with a big fiberglass cookie inside the frame (under the Y that the stax cookies usually sit on top of).

Cool. Thanks Eric. I'll just have to wait and play with the different drivers and dampening then. I have the AT-706s too, but they are playing quietly. I suspect a cable or varistor issue and not the drivers, but I'll swap in the ATH7 drivers and cable right off the bat and then that will rule out the energizer box if they play fine with the new drivers/cable. Then I can swap the cable off the old 706 drivers and rule that out. Either way, I'll have enough drivers to get the ATH7 and AT-706s back to their glory. Found some pads on eBay out of HK that should fit the ATH7s nicely, but I won't post anything up until I audition them.

I've tried to damp the vents of the PMB-80 with micropore:


But there was no deep bass, and less impact compared to more traditional sealing of the baffle:

Foam tape might work too. I've used foam (but not foam tape) on the HOK.

Now I need a small cup of espresso.
