Hi guys, it's pretty much as the title says. My current hifi setup consists of 4 vintage Pioneer speakers (all rated at 120w Max Power each. So probably about 50-70w RMS. They are 8 ohms each.), and a cheapo 300w PA power amp. The speakers are connected in parallel pairs to the L and R outputs on the amplifier. The signal itself either comes from my dvd player, tv, mp3 player or PC through a DIY Phono Selector. I'm looking for a more pleasing sound in general than my current amp. Not particularly fussy about the truest representation of my music or whatever, I just want it to sound reasonably flat/natural and overall pretty good with nice low end. Thing is, all the nice hifi amps I've seen on the net (Cambridge Audio, Marantz, Technics) have a pretty weak output. Usually about 40w a side. I'm looking for at least 150w RMS per side. Is there anything out there that would fit the bill? What are the differences between PA and HIFI amps of the same power? If anybody could shed some light, that would be great!
