@vladtheimpala blanket statements like that are never true. If you have never listen to a naturally warm, engaging and add any other adjectives you want horn speaker, then you have never listened an Avantgrade in a good system.
The Duos Avantgrade, as good and in many cases better than my Sonus Faber Aida, the Trio leaves the Aida in the dust, as it does my Tannoy’s, or any of the other speakers I own, including the Wilson.
if the Avantgrade sound harsh, then it is either the system connected to them or the music or the room placement.
if you are ever around Barcelona, let me know, I will let you listen to them with any of my amps, including my Audio Signature Ginrei and the soon to come The Legend. If you don’t like it and find the music to be engaging and as real as you have listened, I gladly buy you dinner.
