£15k $22k to spend on speakers...but which?

Great stuff,....very funny!!!

On the speaker choice,...from what I've heard on that list, you may wish to re-target your list and look for a speaker with very fast, hyper-accurate and deep bass (no Sub required if the speaker is good enough....) that will deliver on rock, prog-rock, pop, techno, etc...the speakers on the list excel at many things but for hard rock, rock, prog-reck, I think you could do better....you may wish to look at Legacy AERIS and Focus SE. They definitely "rock" down to 16Hz and can cover the range of other music you listen to. There are other choices as well, some mentioned above plus others like PBNs, etc.....

ATC SCM 50, Aries Cerat Gladius, Eclipse TD712mk2+Sub

Charles, the speaker/room interface is so critical and when you have limited placement options, you never know. As much as I love Harbeth, I could not for the life of me make the Monitor 30s work in my room. They just hit the wrong nodes (I guess) and they sounded like the bass was absent below 100 hz. I probably could have made them work with a pair of Mapleshade Bedrocks, but I didn't feel like going that route. Good bass, but reduced image height, as I recall. My friend who bought the Pharoahs has very good ears and I believe him when he said they didn't work for him. That's why I insisted on a home audition before plunking down 12.5K.

I have a nice pair of Verity Sarastro MkII for 16k they would sound great for all your tastes in music.

I would likely move up to the Olympica 3 from Sonus so as they are not as bass deficient as the other speakers listed. That being said, the Sonus Faber's have a distinctly different sound signature in comparison to other speakers you listed. All the other speakers mentioned present a more forward sound that gives great immediacy and very present sound. The Sonus are more a bit further back but still provide an excellent level of performance that draws the listener in.

I would suggest to listen the SF's first only to determine if that is the sound your looking for. If you find it too non involving, then its clear the other three speakers would likely suit you better. I might add in the Kef Reference 5 or Blade 2 in your listening sessions as they are a bit even handed on the treble as compared to the Focal, but without any loss in resolution or soundstaging. But listen to the SF's first just to get a feel for their style of sound.
