It seems that Bob and I share a taste in headphones. If that is an early set then I get his reaction, the modified 007 is just a far better transducer. This is especially true if you tend to listen at higher volume levels, that's where the 009 falls apart and the 007 just craves more power. The amp also can't be blamed here as the KGSS is on the warmer side of the spectrum. Me thinks Bob and Tyll could use a loaner amp to try out. Either a KGSSHV mini or a Carbon. The special KGSS Tyll has is great but both the HV and especially the Carbon just step it up a notch. The detail retrieval the Carbon can muster is just absurd...

I might have a picture in some of the archives but I'm not going to search for it. Can't even remember when I had that one.

The actual Stax schematic is in the link I posted.

Hell yeah, I'm famous... Btw. Congrats Tyll on the proper pronunciation of Yggdrasil...

There was a SRD-7 Pro SB too but it is dead simple to do this.

Yeah, there is a BH or two coming.

The 10M90 is an IC so they are far from all being identical. That's why I test them before they go in the circuit.

This is Stax so one never knows but I've never seen a SRA-10S unit that wasn't 100V only. You would have to have a custom transformer made.

The SRA-10S and SRA-12S are identical so this applies: If it indeed a SRA-10S then it is 100V only (that is the reason for the model distinction) so don't run it off 117V like that.

First mini Carbon up and running. I also built an identical full size one so I can see of the proximity of the PSU/AMP sections has any effect. Two more coming including one with an R-core.

Not sure sure, there were no specs with these. They are 3 times the size of the KGSSHV mini sinks though...

Nobody here would be stupid enough to touch a Woo Wee. We don't think it is a good feature to have an adapter destroy our headphones.

Those heatsinks are at least 50% too small for the carbon so it would be a good idea to reduce the current a bit. My mini Carbons should be ready in a day or two. Massive heatsinks to soak up all the power.

It's just the angle of the pic, it's still crammed with amps.

I believe they are called split rivets. Finally installed this despite it still having some PSU issues. It faces an up hill battle against the Carbon that used to sit there.

That's what I was thinking. I also guess that's why I drew up that headphone design two weeks ago...

Yeah, they quoted me 5 million ISK which is about 40K$. The prices here are weird as they are usually the same as in the US, despite the 25.5% VAT. I would get a very healthy discount though...

None of them have this same as the Liquid Lightning crap. If everything goes to shit then they can destroy the drivers plus if the cable fails then there is nothing to protect the user from the drive voltages.

The He90 never fit my head properly so that would be nothing new from Sennheiser. I hope some aspects of that are just a bad joke but I fear Senn have just fucked up quite badly. Looks like they are still using ODO connectors for this one: http://www.odu-usa.com/products-solutions/push-pull-circular-connectors/odu-mini-snap.html 18mm shell, pin and groove?

It's coming in November... Price is retarded...

To mod them to pro bias would mean replacing the drivers. Almost impossible to mod the drivers themselves. The SRM-1, SRM-3 and SRM-313 (the older ones) all have normal bias outputs and similar circuits.

They just copied our work, no doubt about that. The insertion force is a big deal though which is why I adjust all of my sockets by hand. Yup, I'm that nuts.

I'd love to how he's going to retrofit these into old designs. Not so easy to do...

Adding a small angle usually helps.

For the Carbon with normal CCS setup I'd shoot for at least 200mA HV windings. 250mA would be better unless it is a special case where the temp rise of the transformer is tightly controlled.
