Integrated Amp Bargains with good balanced sound?

I looked at a few (20) AMPs and I stil have questions:

1. Should I care about power outlets integrated in a back panel of the Amp? I like the idea of cleaner current.

2. Should I stay with speaker cable clipping or should I switch to banana clips or RCA plugs? Most Amps don't have clips on the back panel but rather RCA jacks (don't like RCA)
I lean towards staying with clips what you say? Any good reasons?

Thank you much.

1. No, you shouldn't worry about the power outlets. They're sometimes a convenience but shouldn't be a factor in your decision.
2. Most of the amps that have been recommended will have speaker 'binding posts,' not spring clips. You'll find spring clips on less inexpensive gear and they don't provide a very secure connection or much contact area. Binding posts generally offer the possibility of using anywhere from two to five connection methods, including bare wire, banana plugs, spade connectors and pins. Any of those are an acceptable way to connect the speaker wire as long as the fit is good.

RCA connectors aren't used for speaker connections on amps like this. The RCA connectors you see on the back of the amp are inputs for sources like a CD player or tuner.

If you click here and look at the picture of the back of the Onkyo A9555 I recommended you can see the RCA inputs at the lower left and the binding posts for two pair of speakers near the center. Those particular binding posts work best with either bare wire or banana plugs (by prying out the little plastic protective caps in the ends of the posts.)

Thank you for your answers. You do not think conditioned power supply form the Amp's transformer would benefit the sound?
Not trying to argue. I am just new to the whole Audio analog hobby.
Aside from simple convenience is there significant benefit in having power coming from the Amp rather than from the wall outlet?

Onkyo cost/feature is really attractive, but my Audio store in Boston does not stock Denon Onkyo Yamaha brands is it because they don't want to compete with Large electronic chain stores?

I used to have a Audio refinement and I am sorry I sold it!! Get one you wont be sorry, you would have so spend a lot even used to do better, the AR complete can be bought for about 450 500 used,to do better used you would have to spend almost triple! I am thinking the next level up would be a Manely Stingray which goes for about 1400 used.This amp while not expensive now soon will be just like the old dynaco st-70 amps getting 700 used new sthey werer under 200.They stopped making the audio refinement and the new amp they make from what I read is not up to stuff,the complete really should have sold for about $1500 new,the only other amp that comes close is the Krell 300i but it will cost you about $900-$1000 used and yes it's better much more power and great bass with lots of air,good luck,Nick

Dkzzz - the AC outlets on the back of the amp are not tapped into the amp's transformers, they're connected to the incoming AC from the wall outlet.
