Super CMoy =)
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...- arspy87

My CMoy!
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...- arspy87

Cmoy + LM386N?
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...- arspy87

Grado Upgraditis
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- arspy87

Finally new toy: AKG K240S
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...- arspy87

Grado dampening material behind driver?
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...- arspy87

My HD497 mods...
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...- arspy87

Does anyone prefer a bright presentation?
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...- arspy87

Got my Chaintech AV710!
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...- arspy87

Recabling a DT231?
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?- arspy87

Help...it hurts...
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...- arspy87

DT440 opinions
Since I don't have the budget for DT880s, I've started looking into the DT440s.

Cleaning DT231 earpads
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!- arspy87

DIY Grado Pads.
(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...- arspy87

Got my DT231's!
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...- arspy87

Grado diaphragm problem?
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...- arspy87

Cable differences
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...- arspy87

Channel imbalance?
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...- arspy87

SR125 opinions and comparisons
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.- arspy87

Do Grado SR-125's benefit from an amp?

How far does Shure E2/E3 go into ear canal?
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!- arspy87
