I have the same streamer, actually 2 of them, and they feed a tube DAC, the Audio Mirror Tubadour (for $1500 or $2800) and a Benchmark DAC3B ($1700). Both are amazing with the opticalRendu. The DAC3B is super clean and clear and the AMT3SE adds a nice bit of warmth and more analog sound, without sacrificing too much. I use the AMT3SE with RAAL SR1a headphones which need warmth and are one best "speakers" I have ever heard. The AMT3SE is great with the RAAL.
