Rsbeck- You can not plug a DAC6 directly into an amp for it is nothing more then a 6 channel DAC, it would need to be used in conjunction with the switchman mkII(preamp). As where the DCC2 can be run direct because it has a built in 2 channel switchman. The Switchman mkII is another $4995, the meitner transport is $4995, so it is a bit more money to use the DAC6. Using the DCC2 all you would need is a transport(and of course an amp and speakers), the DCC2 adds 2 sets of analog inputs as well as the digital inputs, to allow use as a preamp(in the analog domain) for an additional source- tuner, cassette deck or another cd player for example. Hope that answers your querry for I don't know how else to say it.
I did order a transport with my DCC2 but I managed to wrangle up the last modified Phillips :)
