My voltage selector board.

Those look a lot like the Headamp knobs...

I think you should just stay at Head-fi as that's where "feelings" rule and being retarded is the norm.

As I said, this is a solder mask issue.

Only an idiot would draw those conclusions and how do you know they are better quality? I take it you have them do an insulation test on them?

As Soren states, my boards are very different as I never route this close to the connectors. The ground plane has a set clearance so that is never an issue once that is set correctly. One thing does spring to mind and that is the quality of the boards. PCB's are not created equal and what is fine for LV stuff can fail at HV. Just look at the lil'knight boards from back in the day. Utter garbage and a source of a lot of headaches.

The Dynalo is a pretty great preamp but just watch the gain.

I like bunnies...

Much better than any of his posts...ever!

Find me a cheap, broken set of 009's and I can check it out as I have a few sets of 007 drivers here.

They are lacking in the bass but that was on purpose. The Stax Pro series (so SR-X and 4070) all trade bass amount for depth and insight into the mix.

He's even worse than me in that regard so it is all good. The SR-X Mk3 Pro's are awesome though, truly one of the best headphones Stax have ever made. One of my goals now is to try and copy that design and improve it.

Sure blame me...

An excellent depiction of the struggle we face here too. Nobody dates here without checking islendingabok.is first. Literally "the book of Icelanders" and everybody is in it so you can enter a social ID number and see how this person is related to you. One just hopes all the info in there is accurate...

One word of warning, test all 601 pots as soon as you get them. My most recent batch was horrible and I had to throw away roughly half of the pots due to imbalance issues. So test before soldering them in.

The drivers have clearly been replaced so they are no longer 404LE's and worth a lot less too. You can see that the driver is encased in a housing which only came about with the x07 generation and the 404's never had that. Not a red ring on the driver, well then it has been replaced. I had the same thing happen to 4070's I bought and these x07 drivers (probably 507) sound terrible.

They are not SR-404LE's any longer. Those are probably SR-507 drivers so now they are pretty much horrible. Peaky treble with crappy bass? Yup, that's the joy of the 507's.

The specs will tell me very little about their requirements. Goes to show how useless they are but I'd start with the PureBipolar and work from there

I'd love to try the Focal phones but given how much I hate their speakers I'm not optimistic. Like so many other speaker manufacturers they just try way to hard to impress people and end up with a lackluster product. Still I really want to try the headphones.

It's one of my transformers and it is rated for 450VAC when loaded. It all measures just fine.

I would never run one of these with the cover on. The cover reaches 60+°C (so you can fry an egg on it) but the biggest problem is the PSU. The main power transformer will melt with enough hours on it.

It's their own layout but it is a S22.

Yup with a Sigma22 type PSU

Yeah and never discount the power of hype.
