Anyone had significant headfi time with both the Focal Utopia and Ether Flow and can share some thoughts? Kinda curious if the Utopia offers much beyond the Ether Flow.
Yup. I own both. The Utopia is definitely worthy of it's price premium over the Flow (open) IMO. I have had the Flow for a few weeks, and about a month with the Utopia, and to me it's no contest. The Flow, while sounding
very clean and very musical, just doesn't have the same
real life presentation as the Utopia to me. Listening to the Flow, after listening to the Utopia, the Flow sounds laid back and more 'one note', more restrained in direct comparison. The instruments and the vocals are much more fleshed out on the Utopia. There is more layering and better delineation of the music, more hidden depth in the frequencies, more liveliness in both the lower and upper registers. The mid range, to me, is without fault on the Utopia. The Utopia does this without relying on an unbalanced frequency response (brightness), or exaggerated soundstage. The music just comes at you with graceful ease if it's in the recording, or immediacy and incredible punch if it's in the recording. Dynamism.
Compared to most other headphones I've heard the ETHER Flow is a step up in smooth clean detail and clean frequency response and
balance with very little grain, if not a little on the warm side with a
slight bass bump.
The price/performance ratio is high on the Flow. The Utopia is just simply better, by some margin. As I wrote in my review/impressions the
Utopia doesn't sound like any headphone I've heard (uhg, don't make me say 'speaker like!'), the Flow just sounds like a great headphone. The Utopia is a more difficult pill to swallow for the price, but to me it's worth it. I'm keeping the Flow for those times I just want to kick back and listen to background music with a smooth balanced sound. Let the music Flow! It's still an awesome headphone. The Utopia is for when I
really want to enjoy the music and get
completely lost in the experience with zero distraction. I actually find it hard to work with the Utopia on my head as I often just freeze to listen to what I'm hearing. Mostly I've compared them (volume matched as best I can) directly from the Chord DAVE which is extremely clean and transparent to the source with gobs of depth, imaging, and detail on hand.
Another, more simple look at the two is this... The Flow is very clean and smooth and the Utopia is extremely clean dynamic. Regarding frequency response both are very balanced with the Flow sounding
slightly warm.
I will note that with the Flow you must run it in for some time. With most headphones I don't hear much change at all from burn-in, including the Utopia. With MrSpeakers V-planar drivers in the Flow the burn-in is very real. Out of the box the Flow sounded muffled and overly restrained to me. They've opened up quite nicely now. I'll be posting my impressions of the Flow in the appropriate thread, but I need a little more time to nail everything down. Plus I just received different foam to put under the ear pads so I want to try that first in case my first batch had the wrong foam (which is highly unlikely).
To sum up, if you only have the money for the Flow then I think it's an incredible headphone to purchase. If you have the money for the Utopia then it's not even a question of which one to get.
All of this of course is my experience, on my gear, with my preferences, and simply my opinion. YMMV.
