Which transport with my Jay's Audio DAC?

Advice needed.
I currently have a Nuprime CDT 8 feeding a Jay's Audio DAC. The CDT 8 oversamples the  PCM signal incoming to the DAC, and does DSD.
I have followed the discussions of the Jay's Audio CDT2- Mk2 with interest, since it looks to be a transport superior to the Nuprime. However, it does not provide PCM oversampling or DSD; and I think that the Jay's DAC cannot oversample a signal on its own. [Can any DAC?]
The question, then, is which combination is likely to be the better: 1. The Nuprime transport and the Jay's Audio DAC or 2. The Jay's Audio transport and the Jay's Audio DAC? Does the presumed superiority of the Jay's Audio transport more than compensate for the OS-ing capacity of the Nuprime DAC? 
Or perhaps any question of preferring an OS-ing to a NOS-ing transport is simply a matter of taste, and not any sort of objective criterion for making a choice like this?
Any insights will be appreciated.

There is no even one single high end pure cd transport that using OS method the very few that do are cheap entry level transports and that fact saying all.

Sorry Itzhak yes there are.
Selectable upsampling: 1×selectable switch providing three sample rates (44.1kHz, 176.4kHz, 705.6kHz)
And at over $10kusd I wouldn’t call it cheap or entry level.

There are many more if you search, like I said even odd ones from the old days had it, not as many selections as this from Chord but 44.1 and 88.2 I remember.

EG: North Star Model 192 Transport 16/44 and 24/192

There are some transports that upsample, here is CD transport that allows you to pick which sampling frequency you want it to stream (switch on the back), I think remembering a CAL or Arcam transport only, that did that too.

Choose which output sampling rate 44.1kHz / 88.2kHz / or 96kHz you want.

3 sampling frequencies, 44.1/88.2/96kHz, can be selected to compare the sound difference

Thanks, 100% on this, as my discrete 2r2 dac with DSP chip, it can get it’s code completely wiped if I change some programmable features using a cd file that played into it other than pure 44.1, I know my Linn CD12 as a transport is 44.1 but nowhere could I find if the CXC was.

Here is a review of the Cambridge CXC transport only, in it he a/b's against the Oppo 203 this is what he said.

"The CXC sounded cleaner, with smoother, less aggressive treble, livelier dynamics, a deeper soundstage and firmer bass definition than the UDP-203. Basically, the differences were the sort you hear when upgrading digital converters."

Also does anyone know if this CXC is 44.1 or does it OS the digital stream??
