Thanks everyone! The 218 is great, very smooth and detailed, but I feel lacks the body and soundstage I get with even my Marantz 8805 pre/pro. I am almost positive a linear power supply, DAC per channel, etc. would help.

I am sure the 818v3 would fit the bill, but my hesitation with spending $6-7K is that it seems a bit dated with Sooloos development being stopped. I listen to Tidal MQA through Roon, so the older models wouldn't work so well with my setup. Was hoping to find some thing <$4K.
