BEST CD TRANSPORT

Just keep in mind some really expensive transports (and DAC's) use junk wall-wort p-s and you will need to buy an extra box to get a real power supply.

I don't believe that all wall wart SMPS (Switching  mode power supplies) are the same. Like literally everything concerning audio it depends on the level of execution/implementation. The Pro-Ject RS2T transport comes standard with a wall wart power supply (SMPS)  and sounds fabulous. Better than my really fine P.S.Audio PWT which has a linear power supply (LPS).

Yes you can further improve the. RS2T with a good quality external LPS.  A nice option but by no means mandatory. The stock SMPS  with the RS2T is very well done.

Good points. In the case of Pro-ject, an interesting experiment would be compare the DS2T withe external p-s to the stock Rs2T.

I believe that the main distinguishing attribute contributing to the high level of sound quality by the RS2T is the utilization of the Stream Unlimited CD PRO-8 top loading drive unit with its integrated Blue Tiger servo. I strongly suspect this is the major factor.

Charles; you hit it on the head.  The Stream unlimited drives and servo boards are about the best that can be had (except in the case of very expensive transports), and if the output electronics are well done, the sound is quite good.  This is why Schiit uses them in the URD transport.
