Mad jealous. Still need to find one of these... largest AMT driver ever put in a headphone despite being the second one ever produced. AMTs can freak out a bit in the midrange, and theoretically that should get worse with more surface area... but even the smallest driver (ESS Mark 1) has...

The problem is that piezoelectric drivers are inherently compromised on the electrical side of things. This is the electrical impedance graph of an SE-500, measured using an Audio Precision APx555. You are reading that correctly -- 100kOhms at 20Hz... and 1 ohm at 20kHz. Piezoelectric...

While I have toyed around with the idea of custom lambda pads, it's imperative to never replace pads on a lambda signature unless they are expressly designed for it. The ear side volume of lambda signature is kept at a high static pressure (tight seal) to allow for bass extension, and the pads...

Much darker. FR comparison between the two tells you most of what you need to know... most of it. The Pioneers have a noticeable jump right around the "air" region and a hole in the mid treble, while the lambdas sound much more forward and closer to "neutral" if you can get over the collapsed...

Entirely too much. With things like this, one of two things happens: A: The headphones sell for pennies, since hardly anyone knows they exist. Or... B: Multiple collectors catch wind of them at once, and the price goes ballistic. Unfortunately, this was a case of the latter. Rarity and...

The only change right now is the removal of one of the (proprietary) Sony plugs in exchange for a standard 6-pin Amphenol, like the ones you'd find on a Stax energizer. This is quite a simple procedure as long as you can find the (out-of-production) Amphenol sockets and is very much worth it...

After an extended period of searching... Pioneer SE-1000. Pioneer's first and only electrostatic headphone, similar in appearance to Sony's electrostatic offering from roughly the same time period. Three units showed up nearly all at once, with one having it's original box and another...

:smirk:

Leaving this on pause for now after some additional expenses popped up. Will be reopened when I am ready to resume this project.

Excellent seller. Personable and friendly, item exactly as described and quick to respond + ship. Would gladly do business with again.

Resistive to change I will remain. Bump.

If you have these, you know what they are and why I want them. For the uninitiated, for the first few generations of Audeze's LCD headphones, they offered an optional leather-free alternate set of earpads with a matching headband sleeve. These were offered in a brown/tan color as well as...

lol

Even if he had somehow burned a hole from the solder being too hot, the T30 is much less sensitive to membrane holes and sealing than the other fostexen. I doubt it would matter at all.

I'll be clearing out some of my collection soon, which includes a handful of interesting orthos and electrets. I bought these with the intent to restore and/or modify them but eventually bit off a bit more than I can chew... If anyone here wants first dibs on these please hit me up in DMs...
