...protrusion on the lower back corner, presumably meant to fill in the space behind my jaw and make a tight seal. Instead, all it does is push on my *mumble*chiropractor told me the name but I can't remember*mumble* muscle and give me severe neck cramps and pain after about 30 to 60 minutes of...

See http://www.head-fi.org/t/498292/my-diy-electrostatic-headphones#post_6732478 I've been keeping an eye on this too, but haven't worked up the guts to try it yet.

http://www.amazon.co.uk/JnDee-Supply-ADAPTER-Transformer-TRANSFORMER/dp/B00CXYNV48/ is an example of one with a UK plug on it.  Note, though, that that one is a "normal" polarity, meaning positive in the middle and negative on the outside.  The 2107 requires a reverse polarity from that...

You'll actually be much better served by getting a 12vDC power supply locally for your local AC, rather than try to convert from your local voltage to the 100vAC used in Japan. I grabbed a 12vDC 1A wall wart I had lying around and it works great. Couple things to note: 1: some switching wall...

I just got part of my gift from my partner and am listening to some fantastic Jazz now:  Sophie Milman.  Never even heard of her before, never mind heard her music.  I'm loving this. :-)

Do you know whether the output is DC coupled or not?  I see a couple of what look like Wima caps right by the output:   http://hifimediy.com/image/cache/U2-800x800.JPG   But I can't tell whether those are in-line or bypass to ground caps.  They look rather small for in-line caps, and the...

  Sent them a DM? That'll probably show up in their inbox and let them know that IT'S ON LIKE SUPER MARIO BROTHERS! (Hmm... Doesn't have the same ring, but I've gotta stay hip with all you youngsters... ;-)

...these phones.  I was worried that I'd regret spending the money, but I don't.   What's this slope I'm standing on?  It's a little slippWHOA!!!! *falls on ass and slides down toward spending more money*  Looking for a better USB DAC.  Any suggestions for something in the $100 to $200 range? ...

Good call. Like I said, my source is a grubDAC (http://diyforums.org/GrubDAC/GrubDACoverview.php).  It's good for what it does, but its only good up to 48kHz/16bit.  I'll keep researching for something better (this isn't the thread for suggestions, I don't think.)   As for 100vAC, I've got...

Nice! I'm in. Thanks for the pointer. :-)

Sounds like fun.  I'm in the US, but am willing to pair up with anyone anywhere Amazon ships.

http://www.hdtracks.com/up-close  96/24 FLAC version is in the shopping cart.  :-)   I'm really looking forward to my impressions too!  _I_ am ready, but I'm not convinced the rest of my setup is ready yet.  Right now, I just have a grubDAC on my work Linux box.  I suspect that'll be the next...

So, on the subject of "New to Electrostatics," what music/albums do you all recommend as a way to really show off the benefits of cans like these?  Many of my friends are anxious to listen to what all the hoopla is about and I want to make sure I demo them correctly.   My fear is that I...

I like clean, clear, detailed bass, not muddy thumpy phase-distorted bass.  Let's put it this way:  What threw me over the edge into buying the 2170s is when I noticed that the amp was DC coupled.  I've designed and built a number of headphone amps in my time, and one of my pet peeves is the...

...them when I can) for $640 including expedited shipping.  Should arrive Friday or next week, if the shipping estimates are to be believed.   *cue me feeling like an idiot if the other 40 pages of posts have all kinds of horror stories about importing from Japan, or how the 2170 is crap, or...

Forgive my ignorance, I'm still learning how to read and design tube circuits.   Quote:   The trimmer on the 5965 is just a single trimmer in series with the 650 that's there, just to adjust the 650?  As opposed to a trimmer where each side goes to the cathodes and the wiper to the...

I was considering trimmers on the plate resistors, but I confess I'm still learning tube circuit analysis. Trimmers on the cathodes would allow me to balance the bias, right? Would both be beneficial, or would trimming the plate resistor not accomplish much?

That does look very nice.  I've been chatting with Lil'Knight in DM.  Turns out, he's out of the boards but has more on order.  They'll be delivered in a couple weeks he said.  I looked at the low-end build cost and decided it out of my price range right now.  (yes, I know, I'm in the wrong...

As a prototype of a larger project, I've just placed an order for parts and boards for a headphone amp design I'm working on.  I've been "blogging" about it on my G+ profile (https://plus.google.com/106845099405832446739/)  There are several pictures of the process, different layers and the...

Quote:   Any luck finding an amp for the SR-5s?  I'm really curious to know how they sound being directly driven instead of going through the transformer box.

Quote:   What modifications have you made to this circuit (if any), Wachara?  Are your phones still operating with the (220vRMS * 1.7vPtP/1vRMS * 2 (full wave)) = 748vDC BIAS?  I notice you don't have any DC blocking caps on the inputs, is that still the case?   Do you know if anyone...

Quote:   I'm considering building an ES amp kit loosely based on the ciruit in this thread.  Rather than assembling the amp Dead Bug style, where you wire components point-to-point between the tube socket terminals and other stand-offs, I'd make a board that you could just populate with...

Yup, I know about the different bias voltages. That should be easy-ish to deal with. I looked on eBay and didn't see anything that would work for less than $1k, most closer to $2k. I'm hoping that building one myself can be a lot cheaper than that.

I'm borrowing a pair of SR-5s with SRD-6 interface box from a friend to decide whether I want to buy them.   As one would expect, they are INCREDIBLY detailed.  However, the frequency response is not enjoyable for my listening style.  They are bass-light (expected) and mid-heavy (not...
