Stellar Gain DAC/Pre-amp!?

[mtrot]

Rookie question here. I'm trying to flesh this idea out. I just found out about this Stellar Gain DAC unit, and it sounds like it might be just what I need as a first foray into a separate pre-amp(so far, I've only used an AVR as a pre-pro in my system). It would also kill two birds with one stone, as it would also allow me to check out the sound quality of a separate DAC, as opposed to using the DAC that is built into my AVR.

The idea is to get something for two channel audio that has home theater bypass, so as to be able to continue to use my Denon AVR for movies and multi-channel SACD and DVD-Audio. But I want to improve the CD and flac playback I'm now getting out of the AVR. I would also want to get better two channel SACD audio quality than I get through the AVR over HDMI, but it seems that I would have to purchase a proprietary PS Audio SACD player that has the I2S connector to make that happen.

The plan would be to connect my Oppo UDP-203 universal player via optical or coaxial digital to the Stellar Gain DAC--this would be for CD listening. I'd also connect my laptop via USB cable, which would be for listening to flac files off of the laptop. I could also connect the optical digital output from my 4K TV to the Stellar gain, although I would have to set the TV to only output two-channel audio. The Stellar Gain unit would be connected to my Krell FPB 400cx power amp via XLR cables(I'm not sure if this would be a good output impedance match).

The Stellar Gain DAC/pre-amp seems very reasonably priced, at $1,700, for its capabilities and for the sound quality indicated by professional reviews. Plus, near mint used units are available for ~$1,200. Thoughts?
