Does Mcintosh MDA1000 work with DCS Purcell ?

I have the following set up for my sources.

DCS Verdi CD/SACD transport.
DCS Purcell upsampler.
DCS Elgar plus DAC.

My reference amplifications:
Mark Levison No 32 Pre-amp,
Halcro dm58 mono blocks,

My reference speakers
Wilson watt/puppy speakers,

Reference interconnects/cables
Nordost Valhalla digital and analogue
interconnects as well as speaker cables.

I'm thinking about utilising in the place
of DCS Verdi, a Mcintosh MCD1000 CD/SACD/DVD-A
transport, for the obvious reason of gaining
the ability to play DVD-A.

And it has been brought to my attention that
MCD1000 works best with MDA1000 DAC?
If I replace my DCS Elgar plus with MDA1000,
can it actually still capitalise on the advantage
afforded to me (as a believer) by the Purcell
upsampler? Or else can MCD1000 alone works with my
current setup by replacing DCS Verdi?
What other transport besides MCD1000 can play both
SACD and DVD-A ?
