This is so I have another option on my crusade for cheap, used, quality amps. I want to have many options incase the stuff I'm looking at right now gets sold.

Do the current Parasound two channel amps have hum? Not the expensive, flashy Halo stuff, but the normal amp and normal preamp?

These amps seem like a great option but I read about the humming in some Parasounds and it irked me a bit. The last thing I want to do after trying a cheater plug and sorting out the probs is hear a hum from the speakers. If anybody has any links, experience, etc about these models I'd be glad to hear it. Also, how should I go about using the cheater plug? Should I plug everything into a powerstrip with all three prongs then plug the power strip into the wall with the cheater plug, or should I plug things into the power strip with the cheater plug? What brand power strips and plugs are the norm, or will any do(ok, I'm perhaps a bit paranoid on that one )

Thanks again.

The links don't seem to be working.I have owned one Parasound product,it was the PHP850 pre-amp.I had it hooked up to a Kenwood basic M2A amp.I heard no ground hum from it at all.As far as bang for the buck it would be hard to beat.

Power is power. Don't worry about particular brands. I recall one link from the horses mouth where a seller of premium outlets said that he just took regular outlets, coated them in silver, and sold them for a fortune. In other words, no science behind it, and he could hear no difference.

If you're messing with cheater plugs to get rid of ground hum, I'd have your electrical system looked at by a professional electrician. I don't know much about it, but I'd say that a properly grounded and wired electrical system should not have to have cheater plugs in it in order to prevent hum.

I think this is true to a certain degree but when pushed hard power is not all the same.If this were true than any ol reciever could handle the M80's.When you have a harder speaker load there is a differance in power.Not all recievers will push the 80's but most seperate amps should do fine.

I think that's a fallacy. You're talking about power supplies->amplifiers, I'm talking about power->power supplies. The power supplies should be able to handle stuff that's around the right voltage and amperage just fine. If the power supply does not supply adequate power or the amplifiers don't amplify it enough or adequately, then the given amp can't handle 4 ohm speakers.

I'm not quite sure what you mean.If an amp can't handle a certain load what differance would it make where its shortcomings are.

I mean the internal component that actually does the amplifying. I think we're talking at cross purposes here...

My contention was that any given power strip or cheater plug won't make a difference.

Not a biggie... I was a bit confused on how we got onto the amp thing myself.
