I did not have the 800 series but the 702S2. I really thought they were great speakers and they are but was out messing around and stopped by a dealer to listen to Dynaudio again. I was a former owner.
Auditioned Confidence 20 and the Dynaudio Heritage. I was blown away. Not just blown away but went home and thought about it for a couple of days to make sure I just didn’t have a case of wanting something new. Spent a couple of days with my 702 and went back again and listened. There was no going back. I’ve owned KEF Reference 1s, the older Dynaudio C1s. Bowers etc and these are just the best speaker in my price range I could dream of. Seriously incredible compared to the Bowers. But sound is personal.
I don’t think the Bowers strength was imaging. At least for me. The Heritage are so much better.
I know it’s hard when you can’t audition. You may look at Safe and Sound Audio in MA on-line. They have a return policy that might work. Had a pair of returns as well. If buying new they throw in the Dynaudio Stand 20 and unique bolting plate so the Heritage stays in place.
The best Dynaudio has offered in a very long time.
