SabrinaX vs JA Perspective2 Graphene

I can say I find even the lowly Pulsar a far more enjoyable sound

than any Wilson. 

Comes down to personal preference, but I prefer JA.  If nothing else, they don’t require the dealer to come out to place them to get the best performance.  And, personally, I find them more attractive.  FWIW. 

From the measurements alone, both speakers' in room response looks very good, the JA's pointy lower bass making it sound a tad lean overall...

The Sabrinas show a dip in the presence region and a more uniform decay in the bass with a usefully low -10dB point, so you might find them a bit more forgiving than the JA.

They both have low distortion measurements...

BUT, that's all conjecture.

You really need to listen to these yourself, ideally in your room, and if not, to emulate the sonic result with your equipment in your room. For my small room, I would go for the Sabrina Xs
