Vienna Acouctics Beethoven Concert Grand vs. Avalon ascendant mk2

Unfortunately I don't have oportunity to listen Avalons. Complicated situation...I have VA Beethoven Baby Grand and I want to upgrade the sound of my system. I heard the VA Beethoven Concert Grand and the sound is similar, very musical, but the VA BCG have bigger sound/stage. I didn't listen them with my amp but I think they are better than Baby grand. Did you have the oportunity to compare VA BBG and BCG?

The question is if you have proper system to drive such a demand speakers.

VA BBG is the sweet spot in the series.

Many prefer it to the BCG.

You are right about the bigger sound and stage of the BCG as they scale up better with more drivers but I think they aren't as sweet sounding.

If you can go up to the Lizst or Kiss, you will get a markedly larger improvement.

The answer is that I am not sure. I guess that the most important is the amplifier and I have a pretty good amp that has a lot of power-Bladelius Thor  Mk3 Novitas  with 2 x 175w at 8 ohms(and 2 x 340w at 4 ohms).
-I don't know is it good enough to drive properly Avalons?
-Also I don't know much about positioning of Avalons (how much space they need)?
-I am also thinking about keeping Viennas and invest in better CD player(because I have large CD collection) and better cables. My cd player is Primare CD31 and Cables are Kimber KCAG? On that matter I have good combination for new Primare CD 35 and old(but good) Electrocompaniet emc-1up...
Any good suggestions and thoughs are wellcome
