Caphill,
I know you are well versed on Classe equipment so I thought I would ask you this question. I currently stream tidal from my computer via a high grade Audioquest USB to my Classe Sigma SSP. Although the Sigma has a very good DAC, would using a streamer such as a Lumin T2, give noticeable improvement using the Lumin internal DAC connected to the Sigma via an XLR connection?
