I find it very odd that the OP is comparing 2 dissimilar speaker designs- bookshelf vs floorstanders, timing+ridgidness vs musical. Seems like a curiously vs actually interested in purchasing.
The Fleetwood Sevilles have already been deeply reviewed including here and here. I have been closely tracking the SQ version as I hope to likely be able to purchased in the future. Usually, reviews are about new components, so the Fleetwood are not less exposed than other speakers.
Mere words will not tell you how it sounds, and especially if you “subjectively” like the speaker or not. Without hearing, it’s difficult to communicate a musical vs a transparent speaker. I’m chasing both. My main system is transparent, my flea watt system is for chasing tube midrange magic. To me, like the Devore Orangutan 0/96, the Devilles are one of the most musically pleasing speakers available.
