Uhh, where to start? The most important, the sound: Precise, concrete, detailed and warm sound.
My use and environment: DJ mixes, mostly electronic house and techno music. Also casual hifi music listening.
Small room 3.5m x 3m with little acoustic treatment.
Bass: Veeeeery warm and dry sound, with the bass extension -+-10 Hz feature you can play a lot with depending your room environment WITHOUT compromising the other frequencies. TOP feature!! Actually the best feature in my opinion including the wall/free feature (due to my room space). Never boomy bass like my before Adam T7Vs.
Mids: Cristal clear! I can SEE where the sounds are. Great stereo imaging. Very honest mids.
Highs: Defined and precise, exact, with the right amount and velocity where they need to be, not more, not less. They don't hurt the ears after long sessions.
I love also that they have no encoder for the volume adjustment, just -6, 0 and +6 dB, no more volume calibration and errors while setting them up!
Sleep mode feature, thank you to include this Dynaudio!
Addition to the sound, the design is amazing. Beautiful speakers and quality manufacturing. I can feel and see that they are expensive, including the package XD
I'm very happy with them, great investment so far.
