I feel that the ProAc Response 1SCs and Tablette 50 Signatures I currently own have the qualities you're searching for. They're detailed but not analytical. Have a wonderful midrange and are very involving. And they soundstage very well. Wide, deep and with precision. I will say that I think they benefit by having tubes somewhere in the chain otherwise they can be bright. The tubes reveal their sweetness.
I did own Sonus Faber Concertinos which I liked, but just as a previous poster mentioned, I felt they were veiled and less involving than the ProAcs. Very musical and organic though.
I borrowed a friend's Pass Aleph 3 for a month and the ProAcs sounded beautiful with them. Guitars sounded better with this amp than with any other I've tried, and sound staging was very deep and layered. Narrower than my Blue Circle BC22 and BAT VK200 though. I think the Aleph 30 you own shares the same qualities of the Aleph 3 with one advantage. The Aleph 3 had a very low input impedance which made it a poor match with my preamp. Dynamics were a bit anemic, and bass wasn't well controlled. The 23K input impedance of the Aleph 3 was doubled to 47K in the Aleph 30 which should help it to mate with more preamps.
I have not had the chance to audition many of the other speakers you're considering, however I did hear the Spendor S3/5s at this past CES and liked them. They were smooth and musical, and you should know they make a more revealing version called the S3/5se. I heard both with Talk Electronics gear and preferred the standard S3/5.
Now, I'll have to go out and listen to the Green Mountain Audio Europas!
