Yamaha Aventage RX-A1020 Needs some speakers

Room size is 18'x 26' with 14' vaulted ceilings, lots of glass front and back, wood floors and half of one long side wall opens to kitchen.

What will be your mix of home theater/music? If your top priority is two channel music quality, you might want to consider a used McCormack power amp, possibly a DNA 1. Rated at 150wpc into 8ohms, but delivers a lot of current. I believe is also good down to 2 ohms.

This one would be really sweet, but is modified and may be more than you want to spend:

Should you want more power for the center channel, you could always pick up an amp for that.

Thats a big room Bill. With a lot of highly reflective surfaces too.

If it was me, I would get the Parasound A31 at 250 wpc to drive the CM9's and Center. 3K and your done. Comes in Silver or Black. Keep your Yamaha RX1020 as your processor and also use it to drive the surrounds.

Then consider some room treatments or your going to have one very bright sounding system. And the amplifier you choose won't have anything to do with it. Good luck.

For that kind of money, I prefer 3 monoblock amps, maybe Emotiva XPA-1 like mines or Wyred for Sound SX500 or SX1000. If you don't want to spend that much, the Emotiva XPA-3 is a great amp for HT.

Thank you everyone!
