I believe you are referring to the ProAc Response D20R. I can't say I'd prefer to keep with ProAc or change. In the end, it could all be decided on which ones I can get a better deal if there isn't a strong winner amongst the group.
That being said, it's fair to add them to the group:
- B&W 702 S2
- Spendor A7
- Fyne Audio F501SP
- PMC Twenty 23
- Dynaudio Special Forthy
- ProAc Response D20R
