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

George you correct dCS Rossini has OS transport with clock ,Player costs $28,499, the Clock $7499 but they are rare.
In my opinion better to use NOS transport and if you really want OS buy quality DAC with OS and NOS switch option and have the flexibility to choose what is the best for you .OS is very complicated process entry level transports implement low quality chipsets and they can not do OS correctly.OS is not a magical solution to improving sound.
Many in the thread below found the NOS sounds better :

Another interesting essay how OS might harm the sound :

That is interesting.
What are some of the DACs that have an onboard switch that allows the user to choose between OS and NOS mode, even if the incoming signal from the transport is strictly NOS?

For example the Chord 2qute DAC.


Bellow interesting thread that OS just made things worst and why :

"However, the fact that the sample value is only an approximation based on resolution creates problems. Conversion to a higher bit rate, although strictly able to hold all the frequencies (per the above), is compromised because the sampled wave isn’t perfect. Digitisation errors will occur."

My best advice is to buy the Jay transport to your Jay dac substantial improved sound is guarantee.

itzhak1969:

Where is the switch on the Chord 2qute DAC that enables one to OS  an incoming NOS signal? I can't see one on any of the pictures.... and there is no reference to that NOS-OS capability in any of the reviews.

Any other DACs with the feature you claim?
