I hope you had a very Merry Christmas and the New Year will be great for you!
Don’t worry about the thinness you are hearing with the new speakers. That’s typical and the amount of time for break in will very by the speaker make. I will say this, the Focal Sopra 3 had the best overall sound I have ever heard, so I expect the Utopia’s will be much more. I am using the Cerious Matrix speaker cables. What are your speaker cables?
