Hey everyone, So after building myself a typical CMoy for my headphones, I decided to see how far I could push the CMoy technology. I had noticed that my small 9v amp was able to power bookshelf speakers reasonably well, so... I built a 30v CMoy. The circuit is pretty much the same except...

Hey guys, Just figured I'd post pics of my first amp, it's only a CMoy but I had a great time making it, and it sounds surprisingly really great! I'm using my laptop as a source and either Grado SR225s or AKG K240s. I was surprised how much the bass response has improved, and also how it...

Hey everyone, I've been trying to build a cmoy amp for the past couple of days, with some difficulty... I'm suspecting it's the op amp causing the problems (I'm getting no signal, or a very low garbled signal), so I was wondering if anyone here has built a cmoy with an LM386N(-1) op amp and...

Looks like I've fallen for it again - I started with SR80s, moved on to SR125s a year later, and now another year later I just ordered SR225s. Should arrive in a few days, can't wait

It's been a while since I've had the chance to keep up with everything here (incredibly busy at school...), but with the arrival of summer I finally had a chance to pick up some K240S's at Guitar Center yesterday I love them... my primary can has been Grado SR125s for quite a while and the...

For those of you who have opened your Grados... you'll notice that on the back of the driver mounting piece (plastic circle thing with several holes drilled around a metal plate that covers the magnet), there's a small bit of black fabricky stuff... is that just for keeping dust and whatnot from...

I finally got around to modding my Sennheiser HD497s. I stuffed the earcups with some foam to help dampen the somewhat bloated bass, replaced the front grille (small, drilled holes) with screen mesh, and rewired the drivers. I have pics posted in my project gallery...

I've noticed that the consensus regarding frequency presentation in headphones tends to favor the warm and dark side (though not to an extreme). My opinions are slightly different, it seems - I do like a certain amount of bass, but I prefer tightness and speed as opposed to volume. And as far as...

I came across an AV710 sitting in the clearance section of a computer store I was at yesterday. After seeing the "CHAINTECH" text on the box, and then the model number, it hit me - "oh, hey, this is the card that everyone at Head-Fi likes!" ... so yesterday I left the computer store with a shiny...

Has anyone recabled a DT231, keeping single-side cable? I'm trying to figure out a way to get the wire across the headband, since the groove for the stock one is too small. Has anyone done this?

I am now, again, in the market for bigger and better headphones. The current possibilities I'm looking at are DT880, HD590, and HD595, although I'm open to suggestions. I'd prefer to keep this below $300, and ideally *not* require an amp (these would be home cans - driven through receiver or...

Since I don't have the budget for DT880s, I've started looking into the DT440s. I'm curious about opinions on these 'phones (HeadRoom seems like them), and particularly any comparisons with other headphones that anyone could offer (SR125, DT231, HD497 if possible, but I'd love to hear any...

Any ideas about how to clean the velour earpads on the DT231s? The thin fabric covering for the driver grille is attached to them, so I'd like to make sure I don't damage that in cleaning. Thanks in advance!

(I have SR125s, by the way.) This started out as just a fun project just for the heck of it. I took some thick-ish foam and wrapped it tightly around the driver, cut it to fit, and then used hot glue to seal. After that, I wrapped some mesh speaker covering from some old speakers around the foam...

I've only listened to a few songs on them so far, so these are just initial impressions. This is all my opinion... So far, I LOVE them. I can hardly believe this is a closed headphone! The sound is surprisingly clear, and I shall elaborate. The first thing that surprised me about the sound...

I recently noticed a channel imbalance on my SR125's - sound deviates to the right. I also noticed that if i put my mouth over the front grille and suck gently, the right diapghramn makes a distinct "pop", but the left is not as distict (quieter, smaller) and sometimes is accompanied by a...

I'm curious about different types/purposes of cable and their effect on the sound in headphones. Regarding material, what sort of differences are there among, say: copper, silver, gold, combinations of those, other metals? Also, what about wires that are used for different purposes - for...

When I listen to my SR125, I've noticed that the sound seems somewhat devated to the right, like there's more volume or something. I can't tell if this is due to the fact that I have a cold (bad sinuses, etc. affecting ear), or if it's in the headphones itself, or what. Switching the earcups, I...

Is there any difference? I think the MSRP for the Portapros are $50, but I saw the Portapro2 at Circuit City today for just $30.

My SR125 has gone through a multitute of mods due to my extensive curiosity about all my electronic toys. First, I decided to play a bit with the lettering. I wasn't a fan of the cheapie-looking silver paint: So that wasn't really anything significant. Next up, I decided to replace the...

I'm looking for a pair of closed, isolating, low impedance headphones for around $60 max. I have a pair of Grado SR125's right now, and I'm very happy with the them, so I'm hoping to preserve the Grado sound if possible (I'm very open to thoughts on this. What I'm basically looking for is a...

I haven't seen much about the SR125 in comparison with the rest of the Grado line. I'm curious if anyone has opinions or comparisons - I've been thinking of potentially upgrading to the SR225 or SR325. How do the 125s compare to these? Thanks in advance.

Just curious... I have a pair of SR-125's and I was wondering if it would be worthwhile to buy (or build) an amp for improved sound. Has anyone used SR-125's with and without an amp and can compare/contrast? Thanks in advance.

I haven't seen a thread about this, so I thought I'd offer a few comments. I ordered a pair of comfy pads and they arrived yesterday. Remember, this is my opinion, not fact! I haven't done a side-by-side comparison; I'm just using my first impressions (psychological or not) here, which means...

I'm looking into getting some Shure E2's or E3's, but I've never used canalphones before (or even seen them in person). Exactly how far do they go into your ear canal in comparison to earbuds (the "flat" kind; NOT the ones that have a protrusion that fits into your ear canal)? Thanks!
