I agree that Utopia has better dynamics and detail retrieval and overall driver technology is newer and more advanced. However, I like tonal balance on HD800S more. Regarding the soundstage, you are right here but in contrast, Utopia sounds small in expansive recordings (e.g. Pink Floyd). As I said, no one have the same ears and preferences, both are great headphones. In addition, I know a lot audio engineers and they use all kinds of headphones, for example: HD800S, HD800, DT770, DT990, K 701, MDR-7506. Altough they know about Elear, Utopia, Clear, LCD-4, LCD-X, Ether, Z1R, I didn't see anyone with it. Most of them are friends of mine so I sometimes bring new headphones. In their opinion they would never choose Utopia over HD800 series or even cheap HD600. They said that Utopia is sounding too "audiophile". There are a lot of headphone companies because there are a lot of people with different preferences, otherwise we would have only 1 headphone company. HD800S vs Utopia it's like comparing Mercedes S63 AMG with Lamborghini Aventador, and believe me not everyone would say that Aventador is better, it depends. PS: I have enough money to buy and keep Utopia and Dave so it's not like I am convincing myself to HD800S. MacedonianHero, I really respect your opinion and I love that you enjoy your Utopia.
