@analogsurviver, After doing more listining between burn in, I have done some A/Bing with the FXD80. The FXD80 has a bigger soundstage, wider, more air around instraments, an airer sound overall! I have been going back and forth with the S500 and FXD80 comparing the sound and I found that when I set the crossfeed in my jRiver Media Center 16, to the most aggressive setting, the S500 sound gets very, very close to the FXD80. They get just as airy as the FXD80, with a very expansive spatial sound.....very encouraging and enjoyable. This more aggressive crossfeed setting does a lot for live performances, with a more lifelike dreamy sound, which I like very much. Classical, Jazz, Celtic, female vocals, are genre's of some of my music that benefit expecially!
Just a few more impressions, as I can make the S500 sound very, very close to the FXD80, it just took a little experimentation! I am hoping more burn in time will open up the S500 to it's full potential.....getting closer but not there yet, just past 30hrs "drum and bass" burn in! They do have a long way to go to match the modded ATH-W1000X in it's delicate beautiful sound though, after comparisons.......but the ATH-W1000X has the DHC cable, still might braid one for the S500 if it continues to improve!
@ cute : Thank you very much for your impressions. It is stll early in the day for the HA-S500 and sometimes a minute variation in settings makes a night and day difference between "meh" and "over the moon" reaction to the sound. Just take your time with the experimentation - perhaps you should wait till you have say 200 hours on them due to changes during burn in. The genres of music you mention are very much the bulk of my listening therefore your impressions are very encouraging. I will download the jRiver Media Center 17 ( 30 day free trial period ) after I receive my HA-S500s and will compare it with crosfeed on foobar2000 and the crossfeed on Maier portable amp kit. For home or recording monitoring I will go with whatever will be the closest approximation to spatial performance of AKG K 1000. For portable I do not see myself running around with a netbook though.
Since you mention FXD80 - I have never heard it, yet in measurement graphs I see some potentially troublesome spots; I mean few rather sharp peaks
visible in FR with coresponding shifts in phase response. Can you hear any discontinuities at those points? Since FXD80 is IEM, it may well be difficult to pinpoint this consistently from one listener to another due to resonances in each respective ear canal that will invariably be different from person to person, possibly masking those deviations of FXD80s - anything of the sort that might have an analogy in sound of HA-S500 ?
It is hard to wait for my pair to arrive, with only what I can do at the moment is to - drool - lol !
