Best speaker that Proac ever made


Hello,
What do you believe to be the best speaker that Proac ever made ? Stand mount and tower versions. Not limited to the reference series or any other speaker series that Proac made.

I have owned the Response 1.5 as well as the D15 and have heard the 2.5 and the 3.8. The 3.8 is not just the best Proac speaker I've heard, it is one of my all-time favorite speakers. It had a natural rightness to it.
I heard the Response D40R with a Grommes phi26 a 1.75 SET amp and was blown away by the sound, the quality and the volume
