Megatron Electrostatic Headphone Amplifier

I used the 1200V Mundorf Supreme caps because they look pretty... -
No, that would be something Cavalli would try...i.e. rather stupid and sound like shit.

Round two of my DIY 'stats. Again using SR-X driver shells but now with my own bias rings (laser cut aluminum) and 1.4um film. This is more of a test bed for different glue and coating ideas but I have to say it sounds bloody awesome. I haven't received a large shipment of custom earpads so these are just using what I had sitting here. Alternating between some cheapo Fostex TH900 clones off ebay and A-T leather units. The sound changes a bit with the different earpads but not by a great deal. I did try some old SR-007 pads and I didn't like them at all. The thin, non-angled, A-T pads are excellent with this setup. The sound is very lively, energetic and punchy. I'm also narrowing down on the kind of soundstage I like, small but very precise. Now the small drivers will never beat the larger ones in terms of bass output but the super stretched 1.4um film is pretty impressive here. I don't find them bass anemic at all even though they clearly roll of earlier than the 007's. Next steps are more tests and I'm finishing up some new driver designs. Not the cheapest option but I'm going to try to make as many prototypes as I can so I can test back and forth easily. Guess I'll need some more storage space for the headphones then... In other news, I was looking for some earpads earlier and came across the Mr. Speakers Electrostatic pads.... now what the fuck are they smoking? Huge internal area for an electrostatic? This is the same amateur hour as King Sound.

Better CCS, batteries work now and it is a shit ton less parts. Also far less noisy which is a large problem with the T2.
-
It's been a long while since we did the simplified and improved T2 but it won't sound like the real deal. Better yes, but not the same.

There are a lot of crap dacs out there but something like the Denafrips and Soekris are excellent. Made me retire the MSB...

Yup, we can do that. I'll get it all in a more permanent place though before we post links. -

Given Kevin's retirement, we had to move the files so I put them here temporarily. I might move them again soon though.... -
I have no idea.

When you say it, that looks like a steel Modushop chassis with a new top plate and wooden side panels. Cheapest possible crap then... The perf boards are just retarded. I mean why would you do that, there is no good way to mount the tube sockets compared to a proper pcb with large slots to securely mount them. Ohhh and a RK27 volume control in a 12000€ amp? Are you fucking kidding me?

Yeah and I like my quote above in Russian...

I don't think there is anything slow about it...

Jötunheimar is the "world of the Jötuns" aka the gods.

Ditto!!!

It's even prettier in person. So...when can I get one?
-
The DC-DC converter.
-
Make sure to measure the noise as that's the main problem with these
-
You can also adjust the spring to give it a bit more lift. Some nice pliers and you are good to go.

I wouldn't bother moving half of this stuff. Seriously the Wilsons are pretty much the definition of just set and forget. Me thinks Kevin needs some Sound Lab U series speakers with the frame filled with something super dense. -
There are some gigantic circular hole saws on ebay and while being pretty shitty, they work ok for some light cutting. I'd only use them on aluminum though.
-
Have you tried simply turning the spring inside the earpads?
-
If anybody thinks I won't say something to them in person...well you'd think wrong. As for HF, well it is run by shills so things are never going to change but what they might be upset about is shitheads like this one cutting into their bottom line.
-
High end as in probably worse than the cheap shit? Yeah no...
-
Just read through some of that...fuck some people over there would be in so much trouble over this.
-
Ohh boy, look at this, our new favorite shill is at it yet again: https://www.head-fi.org/f/threads/angstrom-stella-headphone-amplifier.846641/ Hmmm should we just report him and get it over with or spam the thread with links to this one?
