I am going to upgrade my R40s to the 55i or the 600i. Looking for opinions. By the way, I don't have a sub yet (just graduated from college - live in an apartment and the R40's gave me enough). I am a vocal music major and listen to a lot of classical and vocal music. Will the 55i give me as much bass as the R40? As far as tonal quality, not necessarily raw power, which speaker is the best upgrage?
I will be running them through a Onkyo TX-DS 595 (75 watts per channel). Also have CS245i center channel.
