I am solely listening to two-channel music. I am not into home theatre at all yet. Nor do I think I will be for quite awhile. I have an NAD integrated c352 at 80 watts into 8ohms. I am using the M60's as speakers. I have spied Hafler amps (DH500} on the internet for between 250 and 350 dollars. This amp drives I think 225 watts in to 8ohms. I have never used a sub in my two channel music. The NAD fills out my room pretty good. I usually only turn it to around 11:00 to get full effect. I have read where the better wattage could bring out more in the 60's. If you guys have any knowledge what would be best to do......could you please commment.
