you have very nice components. Perfect for a small room. I have similar room size and a much cheaper system and I have two comments
yes, some recordings will sound like crap on a good system. What sounded enjoyable until now, can now sound chaos. I just sold 20 or so albums because they didn't cut it.
what does sound good, should sound incredible with the Totems. They are very musical, good highs and mids. Vocals should fill the room like the sweetest sound. Pull the speakers away from each wall as far as you can, until you may be 5-6 feet away from them, which could be just right. I have slight toe-in, crossing behind my ears.
