You must also consider the impedance for nominal watts. Any amplifier that produces 100 wpc RMS at 6 Ohms can only produce 75 wpc RMS at 8 Ohms (which is what most consumer speaker systems are in today’s home theater). Doesn’t seem like a huge difference, but when you factor in more than 7 channels (25 watts x 7 = 175 watts) it really adds up. On the other hand, if the speakers are rated at a nominal 4 Ohms, many typical home theater surround receivers cannot handle that draw without overheating and shutting down. If you can find a receiver or surround amplifier that can handle this type of load, you’ll be fine because the watts can be doubled into 4 Ohms as opposed to an 8 Ohms load (e.g. 100 wpc into 8 Ohms or 200 wpc into 4 ohms).
