Also believe there's a number of other things at play, viewing it logically:I think as new they were £1300. As I purchased mine ex-demo they were £800, that was in 2013
When upgraded my old Wharfedales to the RS6 it was a no brainer. Likewise when I purchased the PMCs to replace the RS6 they were in a different class bracket. To use a football analogy, it was like Man City playing Nottingham Forest, whereas the TB2 and Dalis it's more lof a Arsenal & Man City match up.
Also I'm so used to the PMC voicing, unless I totally detach the musical brain (almost impossible) it'll be a while to fully define the difference.
In addition, I'm trying not to analyse the two too deeply, listening at the 'feel' of each speaker.
