anybody upgrade from Dynaudio Special 40 to Heritage Special?

Keep the 40’s IMO the heritage are not worth the price to upgrade. I traded my 40’s for the heritage and I am thinking of selling and buying another pair of 40’s. I am using a passlabs 250, so it’s not an amp issue. I will say, the heritage is more transparent than the 40. In my room the 40 has a much puncher and impactful bass, that I miss. The Heritage is also ruthless to the source. Besides the Transparency the heritage has a much large soundstage then 40. 

Just sold my HERITAGE and downgraded?, back to the special 40’s. The Heriatage were too much for my room. they sounded very forward to the point they were hard to listen to.I’m not saying they are bad speakers. They just did not work in my environment. Special 40’s work much better in my room and I can listen all day long. So, I would say if you like the sound of the 40’s and you are in a small space, I would not recommend the Heritage to upgrade.
