i looked at the vienna line,the cheapest floorstanding speaker they had was 1500 dollars,they did sound really nice but the m80s,in my oppinion,out preform them with ease,those speakers also require you to put play sand in them to make them stable!!!!that will be the day i spend 1500 dollars,let alone 5000 on a speaker that requires playsand.the salesworm told me they do that to keep shipping costs down.yeah right....ron
