If i may butt in here for just a moment and derail this topic momentarily to ask a question because it has to do with tubes. I just switched out my Callia DAC for the MHDT Orchid which has a tube output. So far it sounds REAL good (not yet broken in) and i am happy i made the switch. Problem is, i do not have volume control or very little via Tidal. So, my question is, is it possible to use (temporarily) the callia which has volume control or say a Mojo DAC which also acts as a preamp without it bypassing the Orchid? And lastly, i was thinking about getting the Schiit Freya preamp, it has tubes so would that kill the hybrid sound i now have or enhance it? Any comments, good or not so good would be helpful...
