Re: Sierra 2 - Back they go ...
If you placed different speakers (i.e. Not Sierra-2's) in the exact location as the Sierra-2's and it was like suddenly listening with foam earplugs, all settings being equal, then it is definitely the speakers.
As for the HT.....makes sense as that is not as revealing to different speakers, especially since they are playing with multiple speakers of a different brand.
