Thanks for the feedback guys :)
Besides one not yet finished diy project of mine I have not. Then again I am not that experienced with portable headphones. I was comparing Mikros to full size headphones because I lack proper reference in world of portable headphones. I like Mikros with classical. Especially I enjoy string instruments, particularly cello. I just wish Mikros had bigger soundstage. For me it is particularly important with classical music.
Actually, from my experience with the SA-5000--which had a regular tendency toward shrillness or stridency in the HF with certain genres/recordings--I think the MLs resolve treble better. I have a "bass-light" stock pair with particularly exceptional treble extension and midrange adroitness that resolve cymbals and bells extremely well, and with a speed and deftness rivaling the famously quick SA-5000.
SA-5000 is definately shrill sounding headphone that needs to be paired with suitable gear. I love SA-5000 but I consider the excessive brightness a design flaw. Mikros do have more natural and detailed high end than Sonys. There is a line where excessive brightness starts to kill detail at top and SA-5000 crossed that line. Of course every person has their own limits, some are more sensitive to sibilance and harsh highs than others.
Mikros do compare really nicely to SA-5000 when talking about fast headphones. It is really impressive how they managed to do it in a closed small housing. This is one of the main reasons I would have liked to see a fullsize version. They could have done wonders with fullsize cans...
Next-to-lastly, I think the Mikros 90 accurate 3-D rendering does more justice to a recording than the unnaturally "larger than life" depiction of, say, something like the K70x. I actually get a better sense of space, and even a better sense of [actual versus "virtual"] largesse, with the MLs.
It has been a long time since I had K701 but I agree with the unnatural soundstage thing. Besides overall sterility compared to K501 it was my main complaint about K701. I love huge soundstages but it needs to be well proportioned. Akg's had huge width but less so impressive debth which sounded really weird to my ears. I would take Mikros soundstage presentation any day over AKG's. It is when compared to headphones that do big soundstage properly (DX1000 is amazing with it) mikros fall short. But then again, small, affordable, closed...
Those quality control issues are a trouble indeed. Makes giving impressions less usefull when nobody can be sure which kind of pair one has. For that reason it is even more iappreciated that people have multiple pairs. You are doing a great work Pataburd :)
