pro-ject cd box rs2 vs jays audio cd2 mk3

@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.

Sbooster not Sboost power supply...

Jaymark, I have the LTA power supply and am very happy, but I haven’t compared it with the Pro-Ject power supply.  I believe that Terry / Teajay may have compared the power supplies.  Check out the thread he started a while back on the CD Box RS2. 

Teajay did compare the LTA LPS and Pro-Ject LPS and he did prefer the LTA (Linear Tube audio). Another well regarded LPS is the Fidelizer Nikola Signature. Generally speaking LPS are usually considered a clear upgrade to SMPS wall warts. It's impressive the Pro-Ject is praised for superb sound quality even with the stock wall wart power supply.
