I only say that the dac may not be the problem in itself but the synergy on some frequencies response never mind if it is very good on some other aspects between it and the rest of gear
If this is true, then would logic suggest swapping out only one component at the time (DAC, Amp or Transport) might not be sufficient -- that I might have to try multiple combinations of components? I ask this because you are better at logic ! ;o)

Really-- a standard RCA IC ? OK...
