I am currently using a Yamaha htr-5540 with my new setup for Polk RTI-70 fronts,CSI30 center,R30 rears,and SVS 17-39pci sub. All is well but the sound is a little too bright with the new rti's. This seems to be maybe a symptom of the Yamaha line. I am satisfied with 5.1 sound as my smallish 12x13 room won't allow a 6.1 or 7.1 upgrade. Do you all believe that the hk avr225 would be more of a lateral move in sound or do you think this will help me smooth the sound out a little without sacrificing theater impact? Fire away.
