pro-ject cd box rs2 vs jays audio cd2 mk3

@jaymark,
That seems the  consistent conclusion from listeners who've actually have compared both. Jay's is "very" good sounding but Pro-Ject is better yet.

@jaymark, 
Are your findings done with the standard Pro-Ject  wall wart SMPS or with the optional linear power supply?

@charles1dad 
I am using the standard wall wart power supply.  However, over the next few months I plan to pick up an after market linear power supply.

@jaymark 

Are there any character differences between the 2 transports? Or is it the same but better across all parameters?

@musichead
I would rate the Project transport as better across the board.  Again though the Jay's Audio transport is quite good for sure.   The extra dollars for the Project transport seem justified in my mind. 

Now the big question is the LTA linear power supply or the SBoost power supply the best upgrade for the Project transport?  The LTA costs a few hundred more.  Curious if u or anyone else might have some insight here.
