Emotional and physical engagement are topmost priorities for me. Have you owned any of the smaller Harbeths?
I'm not Arafiq, but I have the P3ESR SE in a second system and currently have the 30th Anniversary Compact 7's in my main system. I've had a lot of different small monitors in the small room where I have my second system and the P3ESR's are forever speakers. I got a great deal on them (I think I paid $1K) and it would be close to impossible to do better for what I spent. At the reasonable volumes I play them at, they have great tone and timbre and detail, but never have a hint of brightness or edginess. For a small room, or if you like near field listening and don't ever play music loud, they are amazing.
The Compact 7s are surprisingly good. I currently have them in my main system. I say "surprisingly" because my other speakers are KEF Reference 1s.
In the past I've had Harbeth Super HL5 Plus 40th Anniversary and Stirling LS 3/6 in that system. I like the Compact 7s better than the Super HL5 Plus and the Stirlings. They are just slightly less detailed, but are "richer" in the midrange and sound more "real" than either of those speakers as well as the KEF Reference 1s. The Reference 1s are "better" in a number of ways, more detail, more dynamics, more bass, slightly better imaging and a slightly larger soundstage, but the Compact 7s are more involving and easy to listen to. I'm really torn about which ones to keep at the moment.
