Denon or Yamaha vs Other CD Transports


Wanted to get opinions on the Denon DCD 1600NE and Yamaha CD-S1000 versus other higher end transports.
These 2 units are roughly around the same price (on Yamaha’s website they show a price drop from $1800 to $1300).
I like the fact that they support SACD.
I have been seeing much feedback on the Jay’s Audio CDT-MK2 Tranport and also the Nuprime, which are pricier.
But I wonder if they are that much better? They do not do SACD but I suppose that would be as I do not have that many SACD’s anyway. They do support I2S connection but my current DAC does not support that but perhaps in the future I upgrade that too.
Currently I am using a Denon DBP-1600 (universal blu ray player) as a CD Transport.

I am sure the Denon and Yamaha would be a big improvement over the blu ray player but I am assuming the Jay Audio would be a huge improvement.
One more question, my current DAC is the Questyle CMA400i.
If I were to get the Jay' Audio Transport, would it be beneficial to go through my dac or straight from the transport to the IA.
Thanks

Yes, it's kind of complicated.  There are a few dedicated transports more expensive than the Jays, and several less expensive.  Each model has a different set of outputs.  A good number of people use players as transports; some seem to work very well.  There are long threads on the forum discussing the various transports currently available.

I'm pretty sure there are gizmos out there that will input one type of connection and output another.  As I favor one-box players I'm not super-conversant with them.  But take a look at this thread for starters.

Wow, I keep rediscovering my age. In following this thread and finding the thread mentioned by twoleftears above, after reading down that thread I discovered I was the one that originally posted it. Sometimes one must laugh at one's self! 

I am still interested in the the use of the I2S interface. There is a pin allocation issue when HDMI is used, though most transports/DACS use the PS audio format if I am not mistaken.  
The PS Audio transport has the I2S and the Wyred4sound dac’s also accept the I2S input. 
Yes, and they use the same HDMI pin configuration I believe. As does the Audio Mirror DAC (same as PS Audio).
