Which transport with my Jay's Audio DAC?

Excellent, celander,.... at last, someone with direct experience of both transports.

Can you tell me a bit more about the comparison you were able to make?

• What DAC did you use with them?
• Did you try many of the OS options [PCM and DSD] when you fed the DAC with the Nuprime?
• And this is always a hard one: could you characterize the differences you heard in going from one transport to the other and back? ...and characterize the various aspects of the sonic superiority of the Jay's Audio?

I appreciate your taking the time to offer your response to my OP.

Good listening.

Both were fed into my Theta Digital DSPro Basic IIIa DAC as conventional Redbook signal inputs (16-bit/44.1k). I posted my results on Teajay’s thread about the Jay’s Audio transport.

TBH, the NuPrime was not any better than my 20-year old CAL Delta transport on Redbook signal processing via the Theta DAC. The Theta DAC has chameleon-like character, revealing the strengths and weaknesses of the upstream transport. 

So, celander, in your comparison you did not try the OS-capability of the Nuprime transport. Too bad.

Thanks though. 

Most of high end brands do not implement OS capability on their CD transports .in my opinion what Nuprime did is very unusual and totally wrong , I really don’t understand your fixation of the OS capability like it’s something good... well it’s not !
Good CD transport has to do only one thing to transmit the signal as pure as possible and let the DAC to do the rest .
Believe me if Jay Audio would thought that OS capability will do their transport better they certainly put this technology on their transport .The best transport is the one which keep things simple OS capability on dedicated transport is no more than sound manipulation .

Sir, you insist [ as you have done before, and before, and {sigh} before] that... 
"Most of high end brands do not implement OS capability on their CD transports. in my opinion what Nuprime did is very unusual and totally wrong. I really don’t understand your fixation of [sic: "on"] the OS capability like it’s something good... well it’s not !"

Why the vehemence? You make it sound as though I have written  many a brief on behalf of OS transports and DACs. I have not. I am genuinely agnostic on the comparative merits of OS and NOS processing.

I read the relevant literature.... And conclude that, on that comparative question, the jury is still very much out.

I think that you have me completely wrong on this choice of whether or not to buy the Jay's Audio transport.... Given my audiophile upgrade thirst, I am positively yearning [with emphasis!] for an excuse to buy the Jay's Audio transport. However, I still have on hand an unanswered question--- despite all the many useful responses to my OP--- namely, which combination is likely to be better:
1. A putatively superior NOS transport [Jay's Audio] with an OS-capable DAC, but in strictly NOS mode [Jay's Audio], or
2. A putatively inferior OS-capable transport [Nuprime] with an OS-capable DAC, in OS mode [Jay's Audio].

No one, I mean no one, who has responded to the OP, has directly addressed THAT question. [celander has come closest.]

Gentlemen... and possibIe ladies....  I do not need to be continually dunned with any more posts about the obvious superiority of NOS over OS digital processing. I do not yet have a view....

Nor is there a consensus.Please have the grace to acknowledge that.

In the OP, I raised a specific question about any likely differences--- based on experience of the components involved-- between options 1. and 2. just noted.

May I ask that respondents stick to that issue.

I WANT to buy the Jay's Audio DAC.... I have the money here in my pocket. But, I still want to know whether the shift from an OS-capable to a strictly OS-capable transport would be a mistake.

I continue to hope for enlightenment.
