Your Pick Between These Two...

I have heard Magico A3s and Joseph Audio Pulsars on a few occasions in a few different systems at audio shows. Magicos, to me, sound a touch antiseptic--not involving. The Pulsars were transparent, dynamic, colorful and truly wonderful speakers. If the Perspectives are anything like the Pulsars--I would run to the Perspectives and not look back. 

What size room and what flavor music?  Then whats your budget for components. Sometimes a sealed box will give you better bass, but a bigger room might need more. 

Yes, I mean't the most recent version of the Cornwall. I have heard the 3's and everyone says the 4's are even better. If you love tube amps these are tops. Add two subwoofers (or more) and you will have a system that will loaf along at concert levels with representative low end which is critical for the "live" effect.

I have heard both, although with different equipment.  If I had to choose between these two, I'd pick the Joseph Audio over the Magico.

I got to hear my music on both the Q7s and the Perspectives in different systems.  Obviously the Q7s are much more speaker and I respected them a lot for what they could do, but I loved the sound and expressiveness of the Perspectives more.  For me, I think there’s something about that JA crossover that just draws me in like no other speaker.  But that’s me.  I think the Vandy Quatro is also worthy of strong consideration in this price range.  Best of luck.
