avr comparison
The SC 55 is a more powerful avr and packed with features. It is a better value IMO. I have an SC 35 and it's performace has been 10/10. The class D amps in the SC55 are the biggest difference. You will not get the power drop with all channels driven with the SC 55. I seen an Anthem avr at a custom shop driving some B&W and a couple of Paradigm towers. The sound was great but the speaker were straining when the salesman went up on the volume. I knew my Pioneer would have not had the speakers straining due to lack of power. Just my .02 cents.
