Dynaudio c1 signature

"powerful tube amps" that would be ideal but $$$$$...Xti16 im interested in DDC dynaudio directivity control...have you noticed some big difference between old and new model...its been said that this tehnology reduce the energy dispersed to the floor and ceiling by 75%...and how this affect on a sweet spot...

The DDC is only on speakers with multiple tweeters (C2 C4 and Evidence). Anyhow it is supposed to drastically cut down on the reflection from the ceiling. It's also supposed to sound much better. That being said I was lucky enough to have an 8 day in-home demo with the original C2's and they were too much for my room so I can't really can't comment on that.

c1 sigs are smaler so maybe they dont need ddc...and your room size where the sigs are based is...when i move i will have 4.60x5.80m room...its small to mid space where i mean to keep speakers so your opinion bout dyns would be useful to me...

The DDC again is for multiple tweeters. My room is 3.66m X 7.93m with the speakers about the middle of the long wall with a vaulted ceiling

OK I've been pushing the Octave with the Tung Sol 6550 solid grey plates and they do go louder than with the EAT KT88's without bottoming out. I believe it's due to the fact the EAT's are a very high transconductance tube. Meaning the EAT's have more control and dynamics. They get pretty d@mn loud - at least for me :-) especially with the TS
