Shahinian Obelisk vs VandersteenTreo

I remember the Shahinian's from long ago. It is a nice speaker.
The Vandersteen is a whole different animal. In my opinion, Vandersteen's will smoke them.
I own the Treo's with a pair of 2w subs and use an Atma-Sphere MA-1 and MP-3 with an Ayre Codex and couldn't be happier.
Your Musical Fidelity amp should have enough power, but I am unfamiliar with their sound. All I can say is when I switched out from a McCormack DNA-1 and preamp to the Atma's, everything came alive. ( I had Steve McCormack upgrade the DNA-1 to monoblocks, so I will have a shoot out soon, and, yes, he knows what he's up against.)

Gdnrbob,
Thanks for your response. I used to have Vandy 3A Sig, and they were nice speakers. However, when I moved to another home, their sound was less than satisfactory. I bought open- baffle speakers and they sounded fine, but I am in a totally new home now, and the OB speakers sound like cr*p. Shahinians sound much better, but I exoect some better performance from the Vandees, as the Obelisks, like I said, are smallish for the cubature of the current home...

Or maybe Quatros?) Have a pair offered at $5200 mint ))

Yes, Quatro's would be the way to go, in my opinion.
The upgrades between the 3a sigs and Treo/Quatro line is significant.
If you are looking at the ones for sale here on Agon, I am looking at them, too.
I really like the Shahinian's, but their design is mostly based on the Bose 'direct/reflection' theory. You get lots of nice diffuse sound, very relaxing, but lacking in structure and definition. A properly set up Vandy will give you a more precise soundstage. IMHO.
