About a year ago I bought the DPA-1 first, then a couple months later the DDP-1, sans PS 5. It took 5 months to acquire a solo PS -5 direct from factory, as no one wants to sell it separately and WOW what an improvement the PS 5 made/makes.
I am feeding it with a slightly moded Oppo 105, where the incoming power and IEC were upgraded as well as replaced the crappy SMPS with a aftermarket LPM from Ebay. I also have a Marantz HD CD-1 that I bought to use as a transport, but it's skipping and I haven't gotten around to finding out the problem, and the Oppo sounds pretty damn good, though far from a TOL transport
FYI I have seen a DDP-1 + PS 5 for sale at the ridiculous price of $1100
