Better 2-channel music


My system consists of the Marantz SR7007, a pair of Emotiva XPA-1 mono blocks, Emotiva XPA-3 for center and surround, Rythmik 15HP sub, Oppo 103, Focal 1000 Be II series front and center, Infinity IL10 surround and back. I listen music from CD and different digital sources and movies from bluray DVD and Netflix, Amazon... My complaint is the Marantz doesn't deliver the quality of 2-channel audio as I expected. My plan is to upgrade either to Emotiva XMC-1 or Marantz AV8802. All suggestions and advices will be greatly appreciated.

If I connect Oppo 103D --> Oppo HA-1 --> 2-channel power amp --> front speakers, would the Oppo HA-1 considered as a good 2 channel preamp? I can then bypass the stereo signal from the Marantz AV8801 through the Oppo HA-1 so it doesn't affect the performance of the 2 channel music when the Marantz is off.

As Loomisjohnson said, just use the Oppo 103 direct into the power amps/s, it has all the outputs you need and use it's own volume control.
Forget about buying another preamp just waisting money, the best preamp is no preamp, and you can do it with what you have.

I don't have a chance to try some quality preamps, but I think direct connection from the Oppo 103D to a pair of Emotiva XPA-1 gives the purest sound I have ever heard. Thank you George and Loomisjohnson.

I'm glad you found a solution. The only thing better than getting a really good preamp, is getting a bad one out of your system. Good job.
