What experience have 009 and 007 owners had with replacing the ear pads for "routine" maintenance?
How often should they be replaced?
What was your experience with the change in sound quality due to replacement?
Are there any choices to make, or just get them from Stax?
I have had my 009's for ~5 years and have.used them somewhere between 2000 and 4000 hours.
Replace when the leather degrades (many-many years), or when the foam becomes soggy (many years again). For me they have been keeping up very well, but from what I hear others may need to change them every couple of years. The usual leather care products may be used.
Sound quality with new pads may change slightly especially with the 007, but with the 009 it's been very consistent in my experience. However, it may take months until I receive the new pads from my Stax distributor, I take that into account.
Main criterion is that they fit in the same space, so the diameter should be the same size - the height isn't an issue except possibly with the four large PS caps - they can't be too tall.
This is what I used:
2 - United Chemicon EKMG350ETC470ME11D 47uf/35V
2 - Elna RFS-50V330MH4#5 33 uf/50V (10 uf original)
2 - Panasonic EEU-FR1A271 270 uf/10V (original value 220 uf)
4 - Nichicon UPT2G331MRD 330 uf/400V (original 100 uf)
I imagine there are others that would work as well.
I can't help much, because I haven't heard the L500 or L700. The SR007 is pretty neutral for my tastes, but it is also more demanding in terms of the amplifier - the M3 is not going to do a very good job with those as they just don't have enough power.

Again, thanks for your help. I'm gonna order the parts soon and go from there.

Is there a way to adjust the fit of the SR-x07 model Lambdas? I have a 407, and the clamp pressure is killing me. If I use my hands to pull the earcups apart just slightly it's fine, but otherwise it's so bad that it doesn't matter what they sound like.
I don't have any real hope that the old trick of leaving them gripped on the box overnight will work due to the plastic headband, and I don't want to risk doing anything that the next owner might not like because I'm pretty sure I'm going to have to sell them.
Are all the new Lambdas like this? My next choice is the L300, but if it's got the same clamp I'd rather not bother.

I can't attest to L300 fitment, have not tried them. But compared to my 207's, L700 is quite a bit softer clamp, and additionally it seems to swivel and articulate better. I hesitate to say perhaps it might be comparatively TOO soft, particularly where the arms of the L700 go around the driver unit. At least on my particular pair, if my headband does develop a failure, I would expect it to be there.
The 207's would take a decent headbanging session clamp-wise, while L700 shifts on my head if I tilt back to swallow my morning vitamins.
Yeah I figured that one out. Again, does the drain current value matter? And I could only find SMD models for the MOSFETs, is it still possible to use these instead of through-hole ones?

No, the resistor is around 300 ohms, so a 100 ohm pot in series with 250 ohms (give or take) should do the trick - I specify 261 ohms in the article but really anything around 250 ohms should work.
