PS Audio's "newer" model transport the Perfectwave sacd does not use the same Oppo Digital cd drive. Because Oppo Digital stopped producing them. Kind of hard to honor a warranty when the replacement parts no longer exist. The newer transport uses a Phillips drive, a Sound United LLC who bought D+M Group then goes back to Marantz buying Phillips in 2001.
I "heard" that PS Audio was to release a brand new transport, but for some reason that was put on hold. That sounds strange considering their latest version is only 3 or maybe 4 years old?
I own the "older" version of their transport with the Oppo drive and from what I've read here I guess I'm very lucky because I've had no problems what so ever. Maybe because I don't use it daily. I used a PS Audio DAC for a few years the DrectStream original DAC not their latest the MK2. For the past 2 years I've been using a Terminator Plus DAC. I was curious about the R2R DACs, so I picked one up. I'd also like to try the Mola Mola DAC from what I've read and heard it's top notch for it's price.
