OK, Uncle, I stand corrected folks.

"I read somewhere that they all had a marking on the plug".

(with apologies to pp312!)   :wink_face: 

 

You will now repent by watching Dave Jones probe USB 3.0 Super Speed Eye Diagrams on a 13GHz scope. :tongue_smile:

 

Keep it up and we will make you watch him align and calibrate a Tektronix 2225... :veryevil:

In less than 1 minute. :(

 

I had time to snag one but I really don't need it so I unfortunately waited the full 15 seconds it took to sellout after loading the page....

FYI, I was able to get onto the waitlist even though it was initially full so keep checking it if you're interested. I might not end up buying so that will free up at least one. ;)

post #5512 of 10424

I just ordered the 250 ohm (for $226), so they still have those in stock

 

EDIT: I looked around, and $226 is not so much less expensive then normal ($20 or so) that I canceled my order. Was kind of am impulse buy :p If I want something open back, I will look around a little more.

Hey if any of you guys like ambient music or something really chill to listen to with the DT880s check out the song from Air called Time Capsule. I got it in .FLAC and DRM free if anyone wants a copy.

 

I wanna hear some recommendations or something new to listen to I might not be familiar with :beyersmile:

That's crazy I was just listening to Air when I read this! ...... Lets see, I'm sure I have a bunch of stuff in here that you would like if you like Air and most all of it sounds wonderful on the 880s. I shall return with a few recommendations, let me see what I can find

post #5515 of 10424

Hey I can't find that Air song Time Capsule, what album/release is it on?

 

EDIT: Found it. Looks like its pretty rare

Checkout Moderat - II, see what you think

 

http://open.spotify.com/album/3slifx1g9Vqn5mbITZWrxb

https://itunes.apple.com/us/album/ii/id667882008

 

Moderat is a collab between Apparat and Modeselektor and I highly recommend Modeselektor if you like Moderat.

 

 

Also checkout Terranova. One of my all time faves. Of course these are in a particular genre that might not be to everyone's liking but I love them.

 

Terranova - Hotel Amour:

and Terranova - Nightporter (Hotel Amour remixes):

 

https://itunes.apple.com/us/album/hotel-amour-nightporter/id546739789

 

 

That's a start anyway. There's so much good stuff out there! Especially when you've got great headphones like the 880s.

Headphone.com's measurements show a tad more bass and a bit less overall treble on the 600

 

 

These measurements each show that one 600 ohm DT880 measured as having less treble than one 250 ohm DT880. Furthermore, while I can't account for the Goldenears ones, the HeadRoom results are from a limited (maybe even just one) number of measurement runs, meaning that positioning and other measurement variables could have a significant impact on the results.

 

Measurements are good for showing the differences between different models by different manufacturers, because these differences are almost always quite significant. Between different product variations you're likely to run into unit variation and measurement discrepancies, which makes things not quite so simple. You'd have to look at lots of DT880s in both impedance ratings and work out if there's a trend. You'd also need to take multiple measurements of each sample and have access to all the raw data in order to work out if a particular outlier run is skewing the final average.

 

Also, allow me to demonstrate something:

 

 

This is the unsmoothed, uncompensated raw data for that comparison between DT880s that people keep posting. At first blush it might look like this confirms popular notions about the subject. In fact, that dip after 10 kHz is not only in a region where human hearing is very insensitive (and many older folks have lost the ability to hear in this range entirely), it's also in the region where measurements are no longer reliable (as indicated in the Goldenears plots). From 8 kHz to 10 kHz human hearing is comparatively more sensitive. It follows that, if the 600 ohm DT880 did indeed have less treble, the deficit in relation to the 250 ohm version should occur in this region, since it would be much more audible. Instead, there's actually more energy here in these measurements.

 

So what's going on? Recall that Tyll listened to both these headphones and heard minimal difference between them. Moreover, he attributed this to improved damping factor, not tonal differences. If there were a 4-5 dB hike in mid-treble in one of the headphones, Tyll of all people (known for his preference for warmer sound) would have heard it and commented. I'd say what we're seeing here is a combination of unit variation and measurement anomalies. Compare the following links:

 

http://www.innerfidelity.com/images/BeyerdynamicDT880250ohm.pdf

http://www.innerfidelity.com/images/BeyerdynamicDT880600ohm.pdf

 

Look at the uncompensated traces in gray. Aside from getting shifted on the chart between sheets, notice that both headphones are pretty inconsistent in the treble region. The 600 ohm one does seem to have that dip in the upper treble in at least one measuring run. This most likely means that this particular pair is posting a deep null there for some reason. Deep nulls are sometimes measuring artifacts. If we had access to CSD charts we could see if the null fills in over time or not. But, more importantly, the stuff from 8-10 kHz is pretty close between both in the uncompensated runs. If you look carefully (it's difficult, on account of how the lines run together), I'm sure you can pick out one run where the 600 ohm version has less treble energy from 8 kHz to 10 kHz than the 250 ohm one. The problem is you can also do the reverse.

 

The overall argument I'm trying to make here is that measurements can be misleading if you don't look at the raw data and don't take into account that measuring headphones is an imprecise science. Further, if you have a premise in mind, it's very easy to find minescule differences in measurements and say that these support your belief. Human hearing is quite a bit less precise than a measuring dummy. You'd have to have a significant and very consistent difference between two headphones before you can actually hear it. Drilling into these measurements doesn't really yield that scenario.

Very good post, Argyris. Common sense raises its pretty head again, thank Heaven.

Forgiven.

 

But only because you're so good looking. :D

Yep, well put Argyris, you raise good points.
