I was asking in terms of DIY.

Has anyone tried 3d printing IEM shells?  

I am inching towards making my own CIEMs, but in the meantime I do need some hearing protection for practicing with my band. I see these nice custom ones http://www.etymotic.com/hp/erme.html but heard they cost at least $200-$400 so would like to make some. I already have ear impressions, and am...

How about these new custom earphone molds: http://www.decibullz.com/shop/custom-earphone-molds/custom-earphone-molds/   I have been following this company for a little while, but there first product was their heat moldable earphone tips that came with over-priced bad reviewed earphones.  Now...

  Another bump. Do they fit?

I just found this thread, and want to encourage all participants. I have been wanting to buy a car charger/line out adapter since the iphone came out, but to no avail. So I hope you guys can find out how to get line out without "accessory warning" Thanks, CP

I just stumbled upon this thread since my V6's are in bad need of some new pads. But it seems the Beyerdynamic 250 pads have been discontinued. What else can I use? Thanks, CP

Oh the model is a STR-SE501 from Sony. Thanks I will try diyaudio

I have a sony amp that I have for about 5 years now, it has started having a problem where the center channel in 5.1 mode will cut out, and when it does I hear a click, like a small relay, and it will come in and out, each time I hear a click. My questions are, 1) What are relays used for in...

Going from just what I've read, the crossfeed may lower the volume too much without having a amp. So I would make the amp first. Brian

Removing R1 seems to have done the trick. Now that the harshness is gone, I will figure out the gain, and add bass boost. Thanks, Brian

I bought the V6's because I needed a set of closed headphones for work.

Quote: Originally posted by Grelkman Don't move on to a different amp yet! The CMOY can be a great sounding amp. Experiment with different gain levels, power supplies, and sources. Double-check your solder joints. You'll get there! Thanks for the pep talk, I need it. If my...

Quote: Originally posted by guzzler you can probably omit C1... what power supply are you using?? g 2 9V Batteries.

Quote: Originally posted by stereth When you say you have a 100K resistor, do you mean the one that goes from +in to ground, or did you put one in line with the input? Yes inline to the input, R1 according to Cmoy's shematics. I may make a PIMETA in the future, but for...

I just built my first Cmoy on a breadboard, and initially I am dissapointed. I am using V6's and source is an ipod, and the output is very harsh, meaning the highs are overly strong, and possibly distorted. I tried changing some resistors, but nothing helps. Any help would be greatly...

Thanks for the quick reply.

Hello, I am building my first amp, a Cmoy, and have 2 questions. 1) I want to add the bass boost, that can be switched on/off. I understand how to hook up the C/R in the feedback loop, but at first thought it seems I would need 2 switches, 1 for each channel. How can I do it with one switch...

New to Head-fi but would love to hear other's rigs. I am in boynton Beach, FL. Just south of West Palm Beach.

How do I use Micro-Cap to create those graphs that tanget has on his site for analysis of different C's to use in the bass boost. I already can do the one for the R, and I see the stepping parameters for the Cap, but how do I get it to run that one? Thanks, Brian

They don't sell these at Digikey do they?

Hello, I want to build me a PIMETA, but I have a question. The Schematics and the Text says to use Op-amp AD8620, but the parts list shows OPA2132PA. I am looking for the best value so let me know so which should I use? Thanks, CP
