I went with a SS model, exaSound S88, multichannel DAC, and Teddy Pardo linear PS. They also make Stereo DACs.
What to look for:
-- Mine will convert, natively, DSD up to 256, DXD up to 32/352.8 and PCM up to 384.
-- Sabre ES9038PRO DAC chip
-- A number of features related to Jitter, Clock accuracy and USB Audio error correction.
I'm very happy with it. Server - USB - S88 - XLR to my Amp - to my X3s.
