I think it's more than different compensations, since the bass at IF is not compensated (nor in other sites). It's possible you have a little bit of leakage in your measurements. For pads that require seal (such as those leather pads), you might need to insure the materials used to couple the...

LOL! Yup. Looking at it brings to my mind "brick", which is not a good thing. Crossfeed in the digital domain is not too bad IMO, but a good feature to have. You know the Sansa Clip+ Rockboxed does some of that. It works to some extent. But it lacks head tracking which I found to be very...

To some extent it makes sense. To some other, not so much. That's a lot of interpolation filters and one obscure "noise shapper". Who knows. If it's a multi-bit 5th order delta sigma, I guess it's not much different from some consumer audio DACs ICs out there. The sampling rate is quite high...

Something like that it seems. Would be interesting to know roughly what the quantization Noise Transfer Function (NTF) is (or the equivalent to whatevs his deal is) as that determines to some extent the level of out of band quantizaiton noise filtering needed. That's quite a large oversampling...

I'm not sure what "pulse array" means, and never heard of "enharmonic distortion" and "noise floor modulation". Maybe he means quantization noise modulation? and I guess enharmonic means some sort of pitch error? Who knows. Also, in almost all cases, as signal gets smaller, non-linear distortion...

I don't think we are disagreeing at this point. Some folks here seem to understand the trade-offs about what they have, and appreciate the strengths of their equipment... until they move on to something else if so they choose, or not.

There is no fuss. It is what it is. The AP and the 1266 are not as low in distortion in some areas as some other cans. The 1266 is a sort of unique can. It's got very interesting bass response and I actually like it. Don't like it's price nor it's looks but some may disagree and I'm kool with...

It's probably a combination of many things. But a suspect the driver by itself may exhibit part to part variations due to Fostex operations. Yup. A good AD is probably more forgiving than some other cans while still mantaining an agreeable tone. It may not be very resolving with certain types...

Like TMRaven said. Driver technology and price does not guaratee performance. Also there are many ways to improve a planar (or any) driver's low frequency performance. Not just knurling or pleating. You need to increase compliance in the benefit for lows and at the expense of highs. There...

Disagree there Paco. Fostex drivers in particular have a lot of issues from lower midrange to treble (and bass if not properly dealt with by the enclosure). Distortion, channel imbalance, FR variance... Like I said before, Dan has to proly do a lot of custom work to make those cans work. If...

Yes. Youtube has it's limitations depending on many factors. The quality of the music recording is a big factor. That said, many times bad recordings can become more revealing than good ones. Something that sounds edgy will sound bareable through some cans, and completely unbareable in some...

Try this song instead wahsmoh: https://www.youtube.com/watch?v=j7ZiO_kaf5U This one is not too bad for mids. Some cans sound wonkier than others with this: https://www.youtube.com/watch?v=P51LunEV3Sk Throwing this one too, just cuz I like it: https://www.youtube.com/watch?v=uZ2EQpRq-G8

You should take a listen on those Focals. My only problem with those is that they were tight as hell. Painfully so.   Agree the Fostex driver is difficult. This may be compounded if there is quite a bit of driver to driver variance. Dan likely has to do a lot of driver matching and individual...

That's a little bit bright (and edgy) song dude. It's got some decent quality bass. Best guess is you are better off not using the Beyers with that. Agree an AD and an HD650 would be more enjoyable with this. Particularly the AD which would be able to exploit bass resolution and relax the treble...

  I heard an Orpheus. It's pretty good. Perhaps a more refined HD650. As far as LCD-3F > than Stax Omegas/Orpheus? TBH I prefer the balance of an HD600/650 to most electrostatics. If we are talking about resolution, I would have to spend some time with the LCD-3F to form my own opinion about...
