Try to audition the Atma-Sphere amps and preamps, they match your stated objectives. I am really happy with mine. An exceptional digital only system can be found by pairing an Audio Synthesis DAX Discrete Variable with Atma-Sphere amps, bypassing a preamp in favor of the DAC's own digital attenuation. The DAX Discrete sounds better this way in my system although it sounds great going thru the preamp as well. I use the balanced version of the DAX Discrete DAC. Obviously this setup bypasses the cost of a preamp as well, allowing a greater percentage of your budget to go towards your source component. Truly exceptional sound reproduction is available in either case.
Atma-Sphere amps require careful matching with your loudspeakers, if your preferred loudspeaker is not a natural match for the Atma-Sphere amps, you can use an autoformer called the ZERO between your amp and loudspeakers to provide the optimum impedance match.
