Personally, I rank them:
1. Vandy
2. SF
3. Wilson
This is such a personal priority decision, it really comes down to tradeoffs and priorities. My take is that the Vandy is a more natural, realistic sound that will promote longer listening sessions and craving for a wide variety of music. They will also provide a sublime combo if you ever decide to move to tube amplification.
The SFs IMHO devote too much of their cost to the lovely cabinetry vs. high quality parts that impact sonics. Every time I demo SFs, I try to talk myself into them because they look so great. Each time, something else at the price point sounder better to me.
The Sabrina's are the first or one of the first Wilsons designed by the 2nd gen, who moved the sonic signature in the direction of less hyper-detail, more relaxed presentation...a step closer to your other contenders vs. older Wilson designs. I'd guess this bodes directionally well for their future models. I still find the experience too cool...I find myself actively analyzing every note, never relaxing and hearing the players interacting. Good for a quick demo, but not to listen all night. Just my experience, YMMV. Cheers,
