I've a fairly decent 2 channel setup (Musical Fidelity 308 Integrated fed by a Benchmark DAC1). The 308 splits duty with my home theater as it has a passthrough input that bysteps its preamp. That said, it's paired with another decent 7 channel amp, all fed by a pre/pro processor for home theater duty. It's fairly seamless and I've no complaints.
Might not be the answer you're looking for as you have separate preamp and amplifier already, but a good integrated 2 channel with this type of passthrough helps solve the problem.
