Shahinian Obelisk vs VandersteenTreo

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.

Gdnrbob,
Thanks, but... The Q now is: Treo at $4K or Quatro at $5200? ;-)
But, I guess, this is now up to me. 

I would contact Johnny Rutan and get his opinion (audioconnection).
Also, contact the sellers directly. You can get a better idea of what is being offered.

Sure, Bob, but calling a dealer in the US won’t help me much here in Russia :-)
The items are not on Audiogon. But I have spoken to the sellers, of course. Thinking...
Looks like Quatro is the way to go, since its bass performance can be tweaked.
