Once I take delivery of my CS I’ll see what I think to the HK and if I’m going to do this centre speaker upgrade. I expect factory systems to be below par, but it’s disappointing if the HK is poor. The website talks in detail about their ‘10 speaker upgrade’ and I’d expect all the speakers to be a decent upgrade vs factory
Particularly as I’m coming from DynAudio and I’d expect progress 6 years later!.
Makes you wonder about the other HK speakers installed too…
