I think what has been said in this thread earlier about the Ohm's not having a typical "Hi-Fi" sound is very true. When I was looking at speakers I auditioned the Arros and thought they were a very nice speaker. To me they seemed a bit bright. Loudness and brightness can often be linked to "detailed" or "better". Each speaker will definitely have a different sound and only you can determine which is better for your needs. The one thing that always impresses me about Ohm's is how close they come to making vocals sound like the real thing. But one thing that impressed me about the Arros was the "punch" they seemed to give on certain things like drums.
Right now you are picking up on differences. Just as you did when you took the Arros out and placed the Ohms in your system. If you were to sit with the Arros for a few weeks and put the Ohm's back I think you'd post the same type of reaction on differences you hear :)
One thing you should do is play around and get the best placement for each speaker. Also, listen to a variety of music that you care about. I've never understood how some audiophiles can tailor what they listening to based on the system they have. Your system should be able to play the music you enjoy in a way you enjoy hearing it. Good luck and keep us posted on your thoughts!
