I am also considering a 7700. However I am wondering about the balanced architecture... Will the 7700 perform amplification in a balanced manner regardless of whether you jack into it with RCA or Balanced inputs?

I realize not using balanced inputs would mean obviously that its benefits in noise cancellation wouldn't apply in the Pre-Amp nor in the cable joining the Pre-Amp and the 7700. But I was hoping those benefits at least would apply in the realm of amplification.

I have not bought a Pre-Amp yet but I am considering some that only have RCA jacks. But I might reconsider if using them would mean losing the benefits of the balanced amp.

Thanks
