I'll be there in the morning. I'll have a pair of ZMF Auteurs and a pair of DIY electrostatic headphones. I'll have a modi 2 uber, a vali mini, and maybe a NAD 3225 with a step-up transformer box as amps. I have a DIY soekris R2R DAC, but it only has an optical input, so I'm not sure what I'll...

I would not be able to make it on 5/18, but I seem to be in a small minority on that. 5/11 does work for me, if that's an option that works for more people.

I finally finished my headphones today. I'm listening to them now. They sound pretty great, but have very little bass. I'm assuming that the tension is just too high. Would heating up the diaphragms reduce the tension? Also, the dust covers crinkle whenever I move my head. They're 3um mylar the...

The Bottlehead Crack is always a great option for high impedance headphones. It's often talked about as a good option as a starter kit because it's not very hard to build, and has great instructions, but it's still a great amp. The Jonokuchi is another design to look at. It's not a kit; you...

They were 250 ohm

No, but I think it was in some way related to my amp or dac. Since then, the right driver of a pair of modded DT880s and 1more triple drivers have died in similar ways, and they were using different amps, but the same DAC. I sent in the DAC (a modi MB) to schiit, and they said it works fine, so...

When choosing sockets for the tubes, can you just use any IC socket or do you need to choose one with extra deep sockets for the tube leads?

Definately not clipping. I'm at a volume of 6 on USB, which reminds me that I'm in the front port on a PC, which may not be ideal in terms of noise. Yeah, switching ports fixed it, and noise went down. Thanks! I wonder if it's worthwhile to invest in a proper USB decrappifier?

My mobius just came, and I'm listening to it now. It sounds great, but there's popping sounds (kind of like popcorn) while music is playing. will this go away after a while or is it a serious problem? I got 2 pairs, one for me, and one for a friend. I'm not sure if his have the same problem...

I'm in the same situation, order 4xxx (can't remember the exact number), east coast USA. 2 pairs of copper. No email yet.

Thanks a lot! So the spacer you solder to is the one without the diaphragm?

HI, When you spray-paint the stators, do you paint the entire thing, or do you use a spacer to cover the outside part? Also, what's the order of applying the coating to the diaphragm and gluing it to the spacer? Which side of the diaphragm gets coated? or does it matter? Sorry if any of these...

Mouser lists the 2SA1312-BL as out of stock and has a lead time of a couple months. Where did all of you get your 2SA1312-BLs from? Digikey doesn't stock them either.

I'll try to make it. If I do, I'll have Modi MB -> Magni 2 u HD480II Audeze mobius (if they show up before then) If anyone wants to hear a pair of 1more triple driver IEMs, I can bring those. I'm hopeful (but not too optimistic) that my DIY electrostatic headphones will be done by then. If...

Maybe because they use much thinner diaphragms, they need to stretch them more

the OP hasn't been online here for almost a year, so he/she might not be making any progress, but IDK about other people. To my knowledge, while it's easy to make a working dynamic driver (this can be done with some magnet wire, a plastic cupcake holder thing, and some tape), it's probably...

The right driver of my T70s died today. It is far quieter than the left. The dc resistance of the left is 230 ish ohms and the dc resistance of the right is about 10 kilohms. I'm not quite sure what happened to cause this. I found the sheepskin leather brainwavz pads (110mm) to be the best of...

Here's a cool idea: http://tubecad.com/2018/01/blog0407.htm

Unfortunately, I have not heard the K550.

I got to compare those 2 during a meet over the summer. From memory, the LCD-2 is more intimate and punchy, with a darker treble than the Amiron, both driven from a magni 2 uber fed from a computer dac. A nicer setup may change those impressions. I didn't find the Amiron's treble problematic...

Alcantara is a synthetic microfiber material. No endangered species here. I'm not an acoustics expert by any means, but I'm pretty sure that pads do make a difference. Tyll has done measurements. But deciding what's best is a bit hard. Some people really like the way earpadless headphones sound...

you could try PM-ing him here

huh, so you don't need to tension the diaphragm at all? Cool new 'phones by the way.

But that takes all the fun out of it :triportsad: And all of the "fun" when you do something dumb with the CNC machine.:wink: Seriously, though, those are very well-made stators. I'm curious about the cause of the difference in efficiency, and the difference in capacitance.

What is the output impedance of your amp? I'm not sure whether the new tesla cans have the same oddity, but the 1st gen teslas all have massive impedance spikes in the bass ( > 600 ohm) so the amp's output impedance makes a huge difference in the bass quantity.
