Good amp for Yamaha receiver and AR speakes

[Koop]

A quick rundown. I have a Yamaha RX-V3300 receiver that was powering a Klipsch Quintet II home theater setup in our old house. These little bookshelf speakers worked great in our old living room which was very small. A 10" Klipsch sub provided the bass.

I built a new house with a large living room and open floor plan. (Living room + dining room + kitchen = 1000 sf ft.) The Klipsch speakers did only ok in the big room. I had a pair of pioneer bookshelf speakers on top of the kitchen cabinets powered by the B speakers output.

I just stumbled onto a pair of Acoustic Research 312HO (4 ohm) floor speakers that I could not pass on for the price. The seller also gave me a DCM KXCC center speaker.

For music the Yamaha is in stereo mode and the sub is turned way down. For TV or movies I switch to the 5.1 setup.

The outside is set up for three pairs of speakers.

I have a Boston Acoustic SP6 speaker selector for when I am ready to hook all the speakers up.

Now I am not sure what to do. Currently I have both the A and B speakers outputs going to ARs. The impedance selector is still set to the 8 ohm option because of the center and rear speakers.

Are the ARs going to cook the Yamaha if I do not switch the impedance selector?

I would like to get an amp to power the kitchen and outdoor speakers and maybe the ARs also but I do not know how that would work exactly.

I know where I can get a Mackie m1400i amp for $200 bucks but I know if it is a very musical amp. I have not heard it yet.

Thank you for your help and input.

Those speakers are quite good, but a terrible load, due to the low 180 Hz passive crossover. That also made those speakers a little loose on the bottom end. Unfortunately AR were well into their decline by the time those speakers were produced. They were getting ready to be eaten by Audiovox, like Klipsch just has been.

You need an amp that will deliver 250 watts into four ohms.

Why to you have them connected to the A & B speakers? The A & B speakers use the same two amps. Do not run another set of speakers on the B speakers, or the impedance will be in the basement and you will fry your receiver right away.

Have a look at Emotiva as their XPA series will do the job.

Thanks for your help. I read somewhere that connecting to A + B was a form of biwiring. Is this true and does it help?

Adcom 555

Adcom 555 amp fell in my lap after Hafler 500 was sold out from under me.

Cannot wait to here new amp in the house.

Any recommendations from the experts on wiring or equipment choice? Speakers are currently bi-wired to the A & B ouputs of amp but no one said if this was right or wrong.

Yamaha amp has pre-out for mains but should I do anything more?

Thanks for your help and time.

What is the price on these like?

I would not hook my speakers to BOTH the A+B speaker posts.

It doesn't improve anything at best, and it may fry your receiver at worst, as TLS Guy says.

Remove them immediately and just use the A or B, but not both.
