hi, how's it going? I’ve been using my xm5 for less than a month, but I’ve already listened to more than 150 hours, experimented a lot with eq, tried it myself and presets from different bloggers, and yours too. No offense, but all this spoils the sound, every small change destroys the sound picture, makes it flat. I came to the conclusion that the best eq setting is OFF) At first I missed a little treble, but over time my ears got used to the signature xm5, now I find their sound amazing. I never took dsee seriously, but I was wrong, it gives the bass both elasticity and clarity, the treble is also brighter, and in general more similar to what I hear through a wire.
