No regrets,
I don't have any direct experience with any of the three you listed either but all three (including tracking down an older pair of Proac 1sc which I have owned before) were ones I was looking at as well as den speaker for a den 13' by 13'. I had pretty much settled on the p3esr it having been the only Harbeth model I have yet to own at one point minus the 30.1 in the current lineup, having 40.1 in my main rig for the past 4 years.
Last minute I became intrigued by all the accolades the Kef ls50 was getting overseas and had someone I trusted tell me I just had to give them a listen. I bought them without hearing them and have been extremely pleased, so much so I posted my first thread in several years a few weeks back on them.
Like the Devore they are rear ported. Kef provides a foam plug with an inner plug that can be removed for a partial tune of the port as well. I have mine mounted high in a built in bookshelf (big no no) that I treated acoustically a little and they sound stellar. I have the port half plugged. They are drop dead on vocals, acoustic woods and strings, and maybe the best piano I have yet heard, they are that solid. I drive them with 20 Accuphase watts and Prism and vinyl front end.
They should be on your list. inexpensive too. Easy to try and resell if they did not do it for you but I have a feeling I know the sound you are after and these have it in spades.
