My vote is for the RME ADI-2 Fs.
Chord Qutest if using the receiver as the preamp since you only have single-ended inputs.
I've only heard the Qutest and it's a nice DAC. I've got a Benchmark DAC3 which is pretty close to the RME. I've used it direct to the AHB2 as well as through the HPA4. Sounds great.
IMO, I'd opt for transparency at the source and fiddle around with tone using preamp / amp.
