I would like to keep my existing high end front end setup but incorporate a
high end surround home theater to my existing system. Meaning that I would
like to add in center and rear speakers and surround decoder.

My DAC has a digital throughput that I can pass to a surround decoder.

Any recommendations on how to best set this up without having to undo and
redo connections every time I watch a DVD?


thanks!

Not sure if I understand what your problem is. Why can't you let the
preamp/preamp-processor/receiver perform the switching function? That
is, the DAC output goes to one set of audio inputs on the preamp, and
the DVD player would have its output (digital or analog) go to another
set of inputs on the preamp-processor (which also acts as a decoder).

Alternatively, you can use the existing stereo preamp to act as
line-stage for the L/R outputs of the decoder in the pre-pro/receiver.
