+1 Lowrider. Look for a quality amp that doubles down in watts from 8 to 4 ohms. I run a BEL 1001 MK5. It is rated at 50 into 8ohms, 100 into 4, and 200 into 2. It will drive many speakers better than many 100 wpc amps will.
WHAT'S THE DEAL WITH WATTS?
I'm considering acquiring a new (for me) integrated, under $2k, to drive my KEF full range speakers. They are very efficient (93db) , 4ohm and rated for 50 - 200 watts. It seems that a good amp with 80 or 100 watts per channel at 8 ohms will take these speakers to any volume I'd want to experience in my medium sized living room. So what advantage/benefit in sound am I going to get with 150 -200 watts, or more, per channel? Is it worth spending more for extra power that will never really be demanded?
