Yes, I compared HD250 Linear I and II to the HD600 and in comparison I felt the HD600 was unfaithful to instrument tonality and dynamic changes due to upper bass emphasis. It's quite obvious on extended listening. The HD600 has a wonderful midrange though, which is what I didn't like about the HD250. I listened carefully to the HD250 and it's pretty close to the HD540/HD560. HD250 has slightly withdrawn midrange and slightly overpowering bass though whilst the HD560 has a slightly withdrawn stereo image compared to HD540. HD800 technically beats all of them but is slightly musically withdrawn so I still prefer HD540II. HD560II is a close second but I have sold all of them now. Sale of some HD540IIs will shortly follow.
I got a little confused in there. Directly comparing the HD560II to the HD600 you say the HD560II is better? More neutral at least? Im really happy with the HD560II but sometimes with rock and music it's not very engaging. But it shines completely on classical and/or orchestral. Newer music in general sounds bad, but that maybe because of the recordins. For instance Radiohead's OK Computer is absolutely gorgeous on the HD560II. To be honest im just curious how these "old" cans can beat the newer HD600.I've tried the AKG Q701 and i prefer mine. Btw, i read that the HD600 is more neutral than the HD650 so it's the "natural sucessor" to the HD560 right (after the HD580)
Im all set on the Vali for an amp. And im looking for a DAC under 100€. Maybe it will be the Modi.
The transducers in the HD580/600 are not physically compatible with the HD540/560. In the 580/600, the transducer is in a removable capsule that inserts into the oval frame. In the 540/560, the transducer is permanently fused into the round frame. There is no way to extract the 540/560 transducer from the frame without destroying it.
Here's a pic of an HD540 II assembly.
I know. i checked and despite the transducers are similar and the mount is simillar between the HD560 and the HD600 they are different. The part that connects the transducer to the cable is straight on the HD600 and on the HD560 is angled (see picture below of my transducer and the HD600 HERE). Even if possible it would require a little bit of DIY/modding. But obviously im not attempting this.
To out of my range. But thanks anyways. Im just wetting my feet for now =P
Even if you had have been able to transplant drivers across, the HD600 transducers have a different sensitivity (and freq. calibration) to the HD540 drivers so you wouldn't be able to mix them.
And also, I think the HD560 drivers can be isolated; they're not fused into a circular capsule like the HD540 drivers are.
I was talking about a complete transplant. Right now if one of my drivers goes caput i think i wont be able to find another replacement. So instead of throwing the headphone out i would be making some DIY with newer drivers. But as i stated earlier that would be a little difficult.
