I own the D100 it’s almost the same except that the D150 can read DSD , higher bit and has special load for the McIntosh SACD transport.
I am using it as a DAC and as a digital pre for my MC152 power amp and the sound is amazing : detailed, transparent, natural a little bit warm and smooth,dynamics is great and huge soundstage. Weeks after I bought my D100 Mcintosh introduced the D150 and if I knew I definitely buy the 150 and not the D100.very high value for money.
