we need to figure out a way to 'seal' the fabric of the 840 pads at least on the inside.  i bet this puts the FR back to being competitive with the OEM pads while adding the much higher comfort of the 840.

I don't have a clue about the physics behind this but what part would you want to seal there? the standard pads have a lot of tiny holes in the fabric infront of the driver. so this can't be a reason for a good seal. I still think it is possible that they don't seal well because I messed with them too much. but I will find out soon since I ordered them again.

 

A possible reason could be that they fit slightly more loose than the standard pads when you install them. standard pads are really tight. solution might be here.

I think the pads material itself it open, lets air pass through easily.  the original is leather and closed therefore allows the drivers a 'sealed box' type loading which I think gives them their proper sound.  I would like to somehow make the shure pads material not breathable at least from the iside to the outside of the cans not necessarily from the center of the pad outward but inward toward the drivers.  In other words is it possible to make the pads 'sealed' like by lining the inside of the velour with some plastic? Is it possible to try this by simply putting some light tape over the inside of the pads to see if it works?

Esteemed 7520-ers,

 

If anyone wants to trade their perfect condition stock 7520 earpads for my perfect condition stock 7520 cord, I'm game. PM me. If the stupidly inflated prices and general unavailability of each item is any indicator, it's a pretty even trade.

Well, either way it's going to be impossible to comletely eliminate leakage with these headphones due to the bassport. And for me it isn't really an issue so I haven't tried to eliminate it or anything.

Any recommendations for an amp for the MDR-7520? I want to use them for PC gaming and I have a Titanium HD sound card in my PC. It doesn't have its own amps so I want to get something to ensure I get the best sound quality possible.

For PC gaming I would recommend a DAC/AMP. I myself use a Fiio E07K, which isn't that expensive, and I'm very happy with it. Granted, it was my first DAC/AMP and I don't have anything to compare it to. But the benefit of a DAC is that you will not hear any electromagnetic interference, which is something you will hear when played straight from the soundcard. The inside of a PC is not meant for high quality audio playback, too much interference everywhere.

If I use a DAC with my sound card, wouldn't I lose all its sound processing and whatnot? Secondly, when I plug in my current IEMs (Sony XBA-3) into the sound card, I get virtually no noise. I don't think noise will be an issue and, secondly, I'd prefer to keep the sound card's sound processing.

Yup, using a DAC will bypass your soundcard. I would still recommend the dac/amp route, but if you really want to only use the soundcard's on-board dac, then you'll have to get a separate amp. Not sure which ones are considered good, and of course, it also depends on your budget. You can get a $100 amp, or a $1,000 amp :)

Depends on what sound card you have. If you have a good quality one then you won't need a dac as the built in one should suffice.

Have the Creative Sound Blaster X-Fi Titanium HD.

How would the MDR-7520 compare to the Sony XBA-3 IEMs? Would the MDR-7520 offer a larger sound stage that would be beneficial for PC gaming? I already have the XBA-3 and want to know if I should just get an amp and use the XBA-3 for gaming or get the MDR-7520 and an amp.

Ive actually never heard an iem that can compare to the soundstage of a full sized headphone. I don't recall the xba-3 being anything out of the ordinary when it comes to soundstage. If you want a large soundstage then an open backed can would be your best bet. Personally I use the audio technica ath-adg1 for gaming which has a fantastic soundstage. However if you prefer closed back then the 7520 will do a better job than the xba-3 IMO.

Bought some SRH840 pads to try and get something with a bit more depth, but they just color the sound a bit too much.

 

Has anyone tried using Beyerdynamic DT-250 pads? They look like they would fit the cups perfectly. Just wondering how much they would affect the sound being velour.

Velour will probably create anemic bass, compared to the stock sound. I tried the SRH940 pads (which are velour) on the 7520 as well and it just took out a lot of the bass. It did significantly increase soundstage though, making it sound more open.
