@ullogu1 - The Dynaudio Heritage Specials are anything but dark. They’re super open and detailed. They are great speakers. I recommend reading the reviews on them with are consistent with my experience with them.
Paired with the Gryphon, the sound is open, balanced, detailed with great bass. I’ve sat listening to the pairing incredibly immersed in the music. The pairing of the Gryphon 120 with the Dynaudio Heritage is straight up wonderful.
