Sony MDR-7520 - Page 25

post #361 of 2340

Would somebody has an opinion about 7520 vs. Kef M500?

I'm looking for a closed headphones to complement my HD600 & HD700.

I already have Mad Dogs 3.1 but I would like to try something different. Thanks

Otherwise, it's just electrical current and the sound signal itself stays the same.

 

Measurements also show that there are no measurable differences between using different cables, other than the resistance in the cables being different.


One thing, though: how do we know that we're measuring everything that counts towards SQ?

There also capacitance in the cables especially for RCA interconnects. I have a certain high premium silver RCA interconnects with high capacitance that will make a difference in SQ but not always necessarily for the better.  Headphones cables usually do not have much capacitance to be concerned with. There is also differences in shielded cable methods for cables being used in high RF environments that can make a different in SQ.

thanks for the resources I raised an eyebrow at that comment myself... because I read otherwise but don't know enough to question it.

 

in this case though and for what he was talking about I think it won't make much of a difference with the persons needs.

I would go with the 7520. It is bassier than the M500 but so detailed and with such great treble. The M500 is really smooth and enjoyable, but I think more like the 3.1 than the 7520. The M500 is lighter but the 7520 is super comfortable, too.

I do see the value in shielded cables. It can greatly reduce interference in certain environments and hence improve the signal quality. And this goes for any kind of cable, whether it's for audio or video, or digital for that matter. But beyond a certain point, there will be no added benefit.

 

And when it comes to audio cables, I'm quite confident that there will be no noticeable difference in actual sound signature between a $200, $100 or $20 cable, other than the differences introduced by different resistance and induction specs (which again will in the end only relate to the volume level). 

 

I really think that most of it is marketing and that there is no need to shell out more than $30 bucks on an audio cable. I once had to buy some speaker cable and the salesperson was telling me that I could only install the cable I bought in a certain way because the audio signal would only travel in one direction on the cable. So I just gave him a funny look and said 'sure, if you believe that'. It's just simple physics, that's all it comes down to. I don't buy into any of the pseudo science and the links Andrew_WOT gave more or less confirm that.

 

And IF someday someone can prove to me that there is an actuall difference, I'm still just gonna go for the $20 cable, because such differences will then most likely be extremely subtle and not worth the 500% - 1000% increase in price (to me anyway).

 

In my opinion the impact in sound signature generally follows this chain: Headphone > Source > Amp, where the headphone will change the sound signature the most, and an amp the least (although in some case you can interchange the source and amp, such as when you use a tube amp which will greatly impact the sound signature). 

 

But yes, this is a contentious topic :) So I don't want to stray too much off-topic from this thread.

Ergonomics is improved big time and the sound quality is slightly better than the coiled stock cable. IMHO only of course as this is a contentious topic. I just feel like the v-moda cable has a bit more focus, not a huge difference, but very subtle. Anyway the ergonomic imporvements alone are worth the upgrade twice over. I like to use the 45 degree side on the 7520 to create "angled connector" so the cable doesn't hit my shoulder striaight down. A la Audez'e.

The stock cable is a very high quality cable. A cheap cable like the v-moda will not make the headphones sound better. (arguably no cable should)

I should shut up on the cable discussion before the thread gets locked.

Just one last one, I promise, almost fell off the chair when saw that.

Audioquest SKY XLR interconnects (2 meter pair)

MSRP is $4,600 :eek:, you should be a hell of a salesman to sell 2 meters of wire for almost $5k. 

post #369 of 2340
I don't believe the v-moda is necessarily a cheap cable just because OF PRICE..
Looking at my super tiny AudioTechnica wire I would not even say you could tell by looks alone either...
Anyway all these cables should be fine.
I agree source and amp should be more important as well..

Sure man. I speak from first hand experience. You speak from theories based on spec sheets.

I actually have V-Moda cable that I use with 7520 and Sony DAP, either my portable is not resolving enough or they sound the same to my aging ears.

Anyhow, for portable use V-Moda is great, can't beat the convenience of the short and thin cable.

Good stuff man. :biggrin:

In my opinion I would go with the Sony's just because I'm sure the sound signature is different from all the headphones you have. The M500s are too similar to the Mad Dogs but in portable form...

Has anyone compared those with Ultrasone Signature DJ, wondering if they are worth the premium over Sony?

post #375 of 2340

Just ordered a 7520 from B&H. Should be delivered in a day or 2. Can't wait.

 

In case anyone is interested, I found a Japanese blog comparing the Z1000 to the 7520.

 

http://togetter.com/li/460531

 

There are a bunch of photos. Some show the difference between the 2.

 

http://p.twipple.jp/zJwlp

 

http://p.twipple.jp/flaYU

 

In the above 2 photos, you can see the size difference of the small hole next to the solder points.

 

http://p.twipple.jp/T6vkX

 

http://p.twipple.jp/xzcTx

 

And in the above 2, you can see the little raised plastic part in the middle -- Z1000 is bare, 7520 has a cover.

 

http://p.twipple.jp/kBLmq

 

And the graph. The red line is the Z1000. 7520 clearly has more low end.

 

The guy modded one of his Z1000s to match the 7520 (besides the 2 differences above, says the white padding material's thickness is different), and then compared the 2.

 

http://p.twipple.jp/MbNIZ

 

Looks like a Z1000 modded to match the 7520 can get pretty close. Except, he says the white padding (he calls it "paper filter") is thicker on the Z1000. So to bring the Z1000 to the 7520 specs, he should have switched the padding to a thinner material. Instead he did the opposite by mistake -- perhaps this caused the volume drop? Says sound-wise the modded Z1000 is in between unmodded Z1000 and 7520. Low frequency has increased to get close to 7520. He finds the mids through the highs of the modded Z1000 slightly more "glamorous (not sure exactly how to translate what he said here)." 7520's mids through highs are darker and tighter.

 

He even created a green sticker for the modded Z1000:
