I am the only one that think the Oppo looks retro and overall not so great?

Everyone is entitled to their own opinion, not all of them have to agree!

Now that we're starting to catch up, here is the often requested frequency response.  This is not an average, it is not smoothed, and it's a single point measurement (vs an average of multiple passes for one phone) for our master reference headphone.  We tune our phones to be within +/-2dB of this curve.
 
As usual, the rolloff that starts at about 1.5K is characteristic of our headphone measurement system, and actually this represents linear.  What's going on in the plot above 5K is very random based on micro adjustments of the phone on the test fixture.  
 
I always hesitate to put plots out as many people expect headphone measurements to look like ruler flat speaker plots, but the reality is above 1.5K peaks and troughs are part of "flat" measurements.

That is a sexy looking graph. Some reference class tuning there.

And for grins, our super-expensive headphone stand (at least today).

Now that is sexy!!!

  Might want to wait for a price on the Oppos - it's possible they will cost a lot more than Alphas.

 
couldn't agree more on that one.

I hope that my pair is on your new 'apple stand'

That really is a great looking graph. Can't wait to get the demo pair!!!

Which should be coming to me very very soon, then on to you bud...............PM me your address by the way.

I think they look dull

Will do when I get home

Hey Dan, is there any form of compensation applied to the measurement here?
 
 
Regardless, the pattern definitely looks very similar to other MD measurements, except in this case the midrange with AD seems much more in-line with the rest of the FR (MD's midrange had a bit of a hill around 800 Hz with purrin's measurements), and overall sweeping balance seems better, though to really see we'd need side-by-side comparison either all with your measurements or another sources.

 

[mrspeakers]

We don't use compensation.  
 
My experience with the compensation curves is they don't apply to our test setup well.

+1. That is a very nice graph. Hopefully my prescription of the sound comes close.

I may have missed our simply forgotten that I've read the answer, but how well are they responding to EQ?

My aversion to EQ has mostly vanished and I value is quite a bit more now

 

[koiloco]

Impressive, great looking measurement graph!  but -/+ 2dB could be quite a bit depending on where in the FR the deviation will fall.  Like my Q701, all I ask for is another +2 db in the low frequencies and I'll be very happy.
 
Dan, is this because of a combo of variances caused by inconsistency in the drivers/cups...?
