I currently have a Sony STR-K900 which, according to its manual is 90W per channel minimum RMS @ 6ohms(5.1). The Harman Kardon AVR 254 is 50W per channel full power @ 8 ohms(7.1). I want to upgrade to the Harman Kardon AVR 254 for the HDMI audio/video processing so I don't have to have HDMI and optic cable for my PS3, and so I can have full 1080p output to my TV.
First question is, will I be able to keep same speakers even tho the impedance changes from 6 to 8 ohms?
Second question is, with the lower wattage, will I still get same loudness from the same speakers?
