Hmmm... looks like I misplaced my dunce cap, eh? OPA2227 are burr-browns...*smacks head repeatedly.* I think what I meant to say, and what I think you managed to read despite my error, is that I like the 2227 much more than the 132/134 chips. Regards, G.N.

I'll second the 2227... great op-amp, and a little brighter than the burr browns, which is good if you're using senn cans... -G.N.

Bradjudy That's awsome! Good work. What type of epoxy did you use? Also, how did you keep the pins in a constant position? I know you used a clay mold, as we've been discussing, but did you just push the soldered pins into the clay, and pray it came out right, or was there some other fixative...

Anybody try Caddock Resistors? Wow are they ever spendy... $5-$7 EACH! However... are they any good? I.E. Any better than the RN55s, or are they just audiophile bait, like the $400 wooden volume knob? Regards, Sermon

That's the model you want. I went looking for one about two weeks ago when I built my Pimeta, and found them VERY hard to find. I read everything in a thread on possible alternatives, and no one has particularily solid advice. In short, you won't find them at mouser, and I don't think you'll...

Dinobite: Yes, the Y is the shell from a canare f-12 minijack. The shell comes off just by unscrewing it from the jack. I don't know if you saw this post, but I've updated my cable: Instead of full thickness mogami w/ tecflex covering on both cables above the y-split, I've gone to a...

Ooooo..... Milling machine have I. Emon, I'll have to give a whack at milling out a plug mold. As you note, the hard part may be finding the small bits. If such a solution would work, there is one further issue: Does anyone know the specs of those little gold plugs themselves? It would be...

Here's something I found. I'm sure it's not news to many, but it was news to me! http://home.t-online.de/home/meier-audio/ An excellent explaination of how to solder the stock cable ends of Senn cables, so you don't have to rip open the plug.... and it also tells why the stock wires are...

Mono: I've considered this too... A couple of problems: 1: Pop the screen off your senns, and look at the connection... it's completely encased in molded carbon-fiber... to get at it, you might SERIOUSLY destroy your cans. 2: If you did succeed, and someday wanted to recable again, each...

BradJudy: Awesome that you tried the mold idea! So... I take it that now the DIY plugs you've created actually 'click' into place with a mechanical connection to the headphone cup, as opposed to just using the resistance of the pin-jacks to hold the cable on? Anyways, thanks for realizing some...

Hmmmm, some musings: First, it sounds like you want portable.... That likely means not stacking buffers, and not using high draw op-amps like the 627s. I have the 8620/10 setup and single buffers in mine (although I understand the 8620 may not be best for the Etys) and I get about 5-6 hours of...

Threw this together over the last few days... CMOYs are so bloody hard, you know? However, they are good medicine... I learned a ton from the first, more from the second, and with the third, I actually understand some of how the circuit works on an electrical level. The Camel tin is just the...

Wow! I'm glad this thread has generated a great discussion on plug fabrication, since this seems to be the crux move in recabling the senns. SuperGonzo: Congratulations on getting your plugs pluggable! How did you do it with just heatshrink? Got any pictures? Emon: Thanks for a great...

Nice to see those caps enjoying some more use... congrats on the build! Good work with the soldering... I find there's something rhythmically satisfying about pounding out good solder joints, but that may be just WAY too dorky for words. Isn't it amazing when you flip that switch....and..... it...

Edwood: Thanks! Heavy, yes, I suppose. Microphonic (this means transfering sound based on things touching the cord, etc? I think I miss-called it telephonic in my original post).... Microphonic they seem not to be. Sure, if you really knock the cord around, it jars the headphones, and...

Thanks guys! It was very satisfying to put a pretty face on all the hard work inside. Now, instead of strange looks and "what's THAT?" from people, as if it might be a homemade taser, I get "oooo.... that's pretty" first. Makes it easier to interface with non DIY humanoids. dsavitsk: I've...

ZMN: Others have mentioned using a dremel to cut open the plugs. I didn't like that idea for two reasons: Dremels remove material, and I wanted as much of the original plug left as possible. Second, dremels + plastic, in my experiance, = hot plastic spraying everwhere from the heat and force...

Ob3ron: Generally, what most have done in the past is just split the Senn connector open, and solder to the pins. This has the major drawback that the pins are plastic, and so as you apply pressure and heat from the tip of the iron to the pin, is starts to move around. And not just a little...

I've redone my Pimeta with maple face/back plates. Lots of fun! Used a japanese pullsaw and a dremel for the drilling/shaping of the holes. The wood is from Rockler Hardwoods. If you do this, don't try to drill the holes with a drill... you will mostly likely crack your plate. And that is no...

This was a very challenging and productive afternoon in the DIY world for me. I recabled my Senn 600s, ditching the cheapy stock cables for something more substantial. In the forums, I'd seen a lot of Canare starquad being used, and some Belden starquad, so I thought I'd give the Mogami a try...

Fresno Bob: Thanks for a great source for a hard to find item... especially since Zippo has stopped putting their cheaper lighters in the nice metal tins, and gone to using wierd plastic junk boxes. I wish people would share their tin resources more often... sadly, the coolest tins usually...

Edwood: Next? Currently I'm working on a snappy interconnect with Mogami Quad cable, canare jacks. I'll post results once I have them, since I've not seen anyone using the Mogami on the forums. I'm sure someone has, but if it's a good alt for canare, etc, I'll let you know. Also gotta finish up...

I'm going to try the wood paneling thing tomorrow, I'll let you know how it goes. Hmm... did the pics work for anyone? THey seem to work for me logged in on other computers (work, friends, etc), but maybe that becuase I'm logged in as me. I'm still figuring out this picture thing, so let me...

Wow! Gold jacks and knob.. that's definitely high on the bling factor, sir. What make are the jacks? Casework is quite challenging. I run the machineshop for a small printing company in Portland, and am pretty handy... but casing my amp didn't quite turn out like I'd hoped. Drilling plaster...
