I'm one of these crazy headphones collector that is considering buying the Utopias. The reason I asked this question is because I think the Utopia will not be significantly superior to my Focal Clears. I didn't mean to "challenge" your opinion in any way. That being said, I think you should compare the Utopia with other cans at a cheaper price point, such as the Focal Clear, Focal Elex, etc. At the end of the day we're all looking for the best price to performance ration in this forum.
Until recently I’ve mostly listened to speakers. So my reference is my TAD R1s, recognizing speakers are a very different animal. That said, I would want my headphones to offer the same level of enjoyment.
A few years back, when I traveled a lot for work, I bought JH Audio Angie CIEMs. The sound isolation is fantastic, especially if you spend time in an airplane. That said, for whatever reason, I’m not thrilled with the Angie. But being they are custom, there is no much one can do with them.
Looking for something better, I decided to try the Utopia, given the numerous positive reviews and because like my TADs they had beryllium drivers. But I underestimated how little sound isolation they offer being an open back design. Rookie mistake.
I just recently got a pair of Truthear. These put the Angie to shame. They sounded so good I thought I’d move a few steps up the food chain and ordered the Monarch Mk2, which I should receive this week. I’m also thinking about getting the DCA Noire. The Utopia are useless if I want to listen to music in the same room where my wife is watching TV.
So back to your question, I don’t have much to say in terms of Utopia relative to other headphones. But I can say the Utopia are every bit as fun to listen to as my TADs. You don’t get the visceral impact with the Utopia of a large floor standing speaker with a 17hz 3db point, but the detailing, absence of room modes, and intimacy of the sound is stunning. Are they worth the money difference versus the Clear? I cannot answer that, but now with a new Utopia for sale, you probably can get a great deal on the original Utopia from many that will want to upgrade.
A couple words of warning. The stock cable on the original model is a huge pain in the butt. It is too heavy and too long. Plan on getting something shorter and lighter. Fog City Audio has some well priced custom cables with Lemo knock off plugs. Also the Utopia are very revealing. I bought a Focal Arche that many recommended for the Utopia when Focal ran the 1000 voucher on these. The Utopia sound fine on Arche even without EQ when you set it to Utopia on the amp output, but I find now with the Topping G5 they sound much better (with Amir’s EQ).
