Vienna Acoustics Mozart Grand v Focal 826V

very different

Who could compare its what you like its your ears and your money.

Hard to compare as they are many miles apart and listening in another room is almost useless  Are the Mozarts laid back at all??  In other words are rock and blues going to sound to soft?  We are not looking for Cerwin Vega here but do not want a surprise.  I used to work in the biz years ago and I thought at the time that many higher end speakers were somewhat designed with classical music in mind and still think so today but maybe not.

The 826 isn't wildly different in general character than the 936's I've got and I wouldn't call them laid back while being fed something like Tool. The dynamics and smoothness allows them to be listened to very comfortably at gut-rattling volume with complete clarity. I doubt the 826V would demonstrate the same muscularity in the bottom end, and the speed and clarity of the poly-glass doesn't touch the F cone, but they're very decent speakers all around. Still, I'm saying check out the 826W if you can find them. 

I have the Mozart Grands. 

Never heard the Focal 826V but have heard their large scale speakers forget the model but in the 25k-30k range. 

Like others have said they are completely different sounding speakers. 

The Vienna will be smooth on the top end. Not nearly extended as focals. Will never come off as bright. 

The mid-range has a bit of warmth to it which can be less or more according to the amplification you choose (probably less with your amp). It has a bit of bloom to it.

The bass goes pretty low in smaller rooms. I could see a real bass head wanting subs (I don't need them). A good all round bass slightly rounded but not to the point where it's loose. Lacks the tightness the focals will have but is capable of "Slam" to some degree. 

Imaging and sound staging are amazing on the Vienna's
 
The focal's that I have heard are going to give you a more lean detailed sound with the anthem. Probably a little bit more forward sounding. They have pretty amazing imaging and soundstaging as well just different presentation. I personal think they are bright but again this is all preference and individual hearing.  

Both can be pleasurable with the music you are talking about given your preference.

Classic Musical vs Detailed comparison.
