floor-stander speaker for "classical"

Totem Arro does not scale up well for orchestral. I would recommend Magnepan if they'll fit in your room. Perhaps MMG Super?

I got Magnepan 1.7s last Fall and they have invigorated my classical collection. They keep full scale orchestra and chorus sorted out; tonal balance is excellent, musicality and clarity great, especially for the price.

What is your budget? Have you considered silverline preludes?

Budget is $2K, or under, and the amps I use are Naim, Rega, and a variety of chip and tube models.

Rega RS-3 are ideal.

Second for the Rega RS3.
