I would attach the photo of my setup, but I don’t know how..Use the system page
I am a big Dynaudio fan. With that said, the special 40 had a poor wrtite up in stereophile recently due to box resonance, which quite honestly is puzzling and completely unacceptable for any decent speaker, never mind a Dynaudio.
X18 gets you into esotec drivers which are a step up from the x12 and 14.
What I use is the Focus XD 20/200 which I bet you would love, but it would mean big system changes.
You could also consider Revel and and KEF, which are phenomenal and very well designed.
Thank you for your suggestion on Revel and KEF. I used KEF, old and Uni-Q, but both are not "my cup of tea", for various reasons. Ever since I bought X12 and later heard C1 at the same dealer, I am thinking about upgrade. Maybe it would be better to save up for C1 Platinum (even gently used) than buying Special 40 and getting disappointed...
Listening Jethro Tull right now, Living In The Past double LP, good old Chrysalis pressing. Nice evening, and I want quiet but great music. By the way, not audiophile wet dream recording, but amazing considering the time when created. I just need that "little bit" that I get when volume goes up. Kick drum and snare are there, with that natural compression of the hit, but no weight I heard on C1.
Or, I'm idealizing, trying to find a reason for upgraditis neurosa...
My Dedicated listening room is approximately half the size of yours. I had used the Ascend Sierra 1’s, but always wanted to try a Dynaudio product. When I purchased my Dynaudio DM 2/7’s the increase in slam, impact and dynamics was startling. In comparison, the Dynaudio bookshelf’s have much larger mid-bass driver over the Ascend’s. The previous suggestion to move up to the X18’s might give you the changes your looking for. Have you also considered the the Excite X34’s?
