I need some recommendations on what DAC to pair with my Klipsch La Scala Speakers (ALK x-overs) which are powered by my Decware Rachel amp.

I am currently using a Wiim Ultra Music streamer which has an ESS neutral sounding Sigma based chip. I suppose it's OK? I have never tried any other DAC so I don't know. There have been lots of raves about R2R DACS and R2R TUBE DACS but I was wondering if that too much warmth to the point of getting sloppy?

I'm seeking recommendations on finding a DAC that is revealing and has great soundstage depth with lots of harmonics for fatigue-free listening.

Anyone have ideas?
