New floor stand speakers

I would consider the Vivid Audio B1. I have v1.5s and would have b1 in a larger room. Vivid makes a great sounding speaker . Detailed and coherent. sounds like there is no box but dynamic.

Where are you located? There are 2 pairs of VMPS RM40 speakers for sale: one on the west coast and the other in the midwest. They are fantastic speakers that will not be outgrown no matter what ancillaries you put with them. Their used price is $2500. I know you said new, but this is a whole lot of good sounding speaker at a price of average monitors. If you like clarity without etch at all frequencies, dynamics, deep, clean bass, and as good of highs as you could want, plus a deep soundstage. I have a friend who comes over every few months and listens and is always amazed.

Does anybody have experience with the above speakers: Crystal Minimissimo, Magico S1.5, Wilson Sabrina?

I'm currently using Proac Response 4, which sund great but I am now looking for smaller size speakers, provided that sound is not compromised. Stand-mount could work too.

Thanks.

I have been enjoying my new Focal Sopra No2's for about 10 weeks now, very detailed, very musical.
I auditioned the Magico's and Wilson's before selecting the Focal's.
Before auditioning the Magico's the salesman asked me if I prefer "analytic" or "musical" speakers, hadn't thought about it that way, for me "musical" was the choice.
For me both the Magico's and the Wilson's needed to be driven to fairly loud levels to sound their best, and with source that has even the slightest harshness, I tired quickly listening to either of them.
Having said that, I think you have selected some of the best speakers made!  Enjoy your search!

If you like the sound of your Proacs, I think Joseph Audio speakers offer similar sonic traits in terms of musicality, imaging/soundstage, and disappearing in the room.  The Perspectives may be worth a listen if you can find them.  Best of luck.
