No nasty peaks on the ex1a. I measured them as soon as I unboxed and my impression is the drivers loosened up a bit by now, so I will re-measure soon. Flat plate rig, so don't use these as absolute measurements.

Owned both es1a and 009 at same time, have to disagree herees1a leaves 009 far behind, not even mention es2a
the soundstage is much better in es1aOwned both es1a and 009 at same time, have to disagree here
Technically the sr 009 was still the more resolving one.
Es1a had a more romantic / warmer tuning and maybe a bit better bass.
Soundstage wise the SR 009 took the crown, especially it's soundstage depth capabilities.
Sold the es1a short after
I had both 009 & 009S which I recently sold but I can say that ES-2A easily out resolves both these headphones. The soundstage is also larger than the 009 with greater bass impact and less peaks in the treble.Read that es2a has some nasty peak in high mids's and high-treble area though wich doesn't make it very refined imo.
Unsure I would call es2a better than a SR-009 for example, certainly not X9000.
Can't speak of es2athe soundstage is much better in es1a
technically 009s is only better in some ways
but still es1a is better than both of them
not to mention es2a
I subscribe to every wordI had both 009 & 009S which I recently sold but I can say that ES-2A easily out resolves both these headphones. The soundstage is also larger than the 009 with greater bass impact and less peaks in the treble.
X9000 has a weird soundstage and presentation to it that I do not like so I would personally choose the 2a over it.
Can't speak of es2abut I decided to skip the hypetrain for now.
Will wait how impressions evolve over time
Unfortunately, after trying the SR-30 on my newer (proven) energiser I can confirm the imbalance is in the headphones and not the SRD-4 adapter.
Mine snapped on the first day I got my pair. It was used; and had aftermarket thick pads.
...........
Luckily I already knew that people modeled adapters, so I got a pair printed; meant for audeze headband.
Sourced not-audeze headband from ali.
The pic from reddit shows, from what I get, is the original adapter. There is also a version for thicker pads and one with an thicker, more durable attachment point.Ok!

Now if I had discovered this earlier....

If we could get machined aluminum arms we'd be all set.![]()
How's the clamp force? The mark II Stax headband assembly is a nice improvement over the original L300 one and I appreciate the greater clamping force.The pic from reddit shows, from what I get, is the original adapter.
Here in Canada the L300 at $699 Can is priced near many mid-tier headphones, and that's excluding the necessary energizer, so Stax should really look at alternatives as faltering headbands appear to have been a long time issue and from what I've read have actually gotten worst since the original Lambdas.As for making one in metal. Could always 3d print them in steel.
I can only speak on the clamping of my, somewhat unorthodox, setup; thicker pads, changed bravket design and knock-off headband.How's the clamp force? The mark II Stax headband assembly is a nice improvement over the original L300 one and I appreciate the greater clamping force.
My uneducated guess is that the failure points are the spots at which the rail meets with the headband; the rails stiffen up the otherwise thin and flimsy plastic.Stax should really look at alternatives as faltering headbands appear to have been a long time issue and from what I've read have actually gotten worst since the original Lambdas.
