I am concidering connecting a Marantz SA-7S1 CS/SACD player directly via unbalanced to the MC275 Mk VI, as unbalanced has volume control. The Marantz has enough output power 2.5 V RMS. The unbalanced input sensitivity of the MC275 is 1.2. Others here have said this will work, I am very interested in what you think?
A number of folks have done this with various CDP's some with good results, others not. The good results seem to be more with using balanced IC's between the units. If you want to read more, search the threads on the McIntosh forum at Audiokarma.
