I was wondering the same thing as far as efficiency of the monoblocks, as I know that receivers power ratings decrease as more channels are driven, in other words a 140W x 7 receiver might only be putting out 80W each channel when all channels are being driven. Anyone know how the Outlaw amps do in this respect if I went for one of their 7 channels in one unit compared to the separate monoblocks?
I figure having separate monoblocks would eliminate this issue, but would require extensive changes to my setup to accomodate the space needed for 7of these things, so I wanted to make sure I considered all options before dropping the cash and making the structural changes.
I don't really think it matters if you go monoblocks or 7 channels. I have the 7700 and it is great. I have it hooked up to an Onkyo SC-PR885P by balanced connectors. No hum or ground loop problems.
The 7 channel amp is going to have large power supply(s) I can't remember but I think the 7700 has two and the monoblocks have seven smaller power supplies. Some people think the large transformers store more energy for large dynamic sounds for a few channels and are better. After all you don't have seven channels going 100% all the time any way. Some say the 7 smaller transformers give more total power and are better. I say it all depends on the audio you are listening to at the time.
The main limiting factor is going to be your power going to the units if you have only one 15 or 20 amp line going into your room and everything is hooked to it you can't supply your amp with enough power. For true 7X200 watt output the line can't handle it.
I have two 15 amp lines with 2 SVS PB12/plus2 @900 watts each
2 AV123 RS1000 mains that have 350watt amps each (just for the 8" woofer-The other speakers are run by the main amp)
Outlaw 7700 is 7X200 watts
Lights and audio equipment maybe another 600 watts total. Projector burns about 200 alone.
A 15 amp 120 volt line has 1800 watts available. (Under perfect conditions)
So 15X2 is 30 ampsX120volts gives a total of 3600 watts available.
If all my equipment is at 100 %( which will never happen) then I need 4550 Watts to run it. I need more juice. (And so do most people)
Getting ready to run another 20 amp dedicated amp line.
I can dim and flicker the lights in my theater if I crank it up past ref.
Just something to think about.
