+1.
Did you try the HE1000v2?
That headphone might have the right mix of good dynamics, punch and detail, but also a slightly more relaxed presentation.
the original HE1000 was often criticized for being too relaxed and laid back, supposedly the v2 update addresses this.
My only real criticisms of the Utopia are 1) the price, and 2) it is a very intense headphone - the sound is energetic and somewhat edgy all the time. That can get fatiguing after an hour or so.
I agree with you TonyNewman, and will probably get flamed over this post, but oh well.
I have tried many sources, dacs, and amps with the Utopia, and it is an Intense sounding, very dynamic headphone,...one of the most dynamic ever! But, on the other hand, it can get somewhat edgy at times, but it is NOT sibilant. I actually hear no sibilance, unless the recording has it.
At times, as others have said, it can sound maybe TOO dynamic, if that makes any sense?
If you love dynamics, and a powerful sound, this is the headphone for you!
It is also somewhat forward in the middle of the midrange, etc.
Maybe I am just used to the more laidback mids on the HD800 and HE-6 too?
I can also hear some kind of dip around 8khz on certain treble sounds and cymbals at times, its hard to point my finger at how exactly to describe it,
It also seems to sound somewhat more 'in your face' than the HD800, HE-6, etc,.in the midrange.
Unfortunately, my ears do agree somewhat with the frequency response graphs on certain sites, which shows the bass being somewhat down below 50 hz, a peak around 1.5 khz, and a dip at 8khz, and some slight peaks above 10khz, plus it sounds just a tad closed in, and maybe even lacking in air, even though the treble is fully extended.
It is however, overall superior to the HD800 with SDR mod, and HE-6, imho.
The 800 has a bigger stage, and alot of micro detail and openness,, but it does sound somewhat shrill, more sibilant, distant, not as dynamic, and alittle lacking in bass compared to the Utopia. The 6khz peak actually becomes more annoying and more obvious after listening to the Utopia awhile and then switching to the HD800.
The modded HE-6 is wonderful, but isn't quite as macro detailed, or as dynamic as the Utopia, and has a some sort of treble coloration that I can't get rid of, but at the same time the micro detail, especially in the treble is outstanding at times.
The bass extension is superior on the HE-6, and it is alittle more relaxing than Utopia.
Staging is similar.
Don't get me wrong, I love the Utopia very much, and greatly enjoy it, but it isn't perfect. Nothing is.
However, even with the slight flaws I hear from time to time, it is still overall about the most tonally neutral headphones I have had the pleasure of hearing or owning.
I can see it as an endgame headphone for many people, and I most highly recommend for people to atleast audition it and draw their own conclusions.
Just my 2 cents.
