I currently own a PS Audio P15 power regenerator, a DirectStream DAC and CD transport. I had the PerfectWave transport before the DirectStream model was introduced, and I found the newer model was well worth the upgrade, especially since I own about 100 SACDs.
The DirectStream CD transport uses a disk handling part provided by Oppo, who decided to get out of the business of providing those sorts of assemblies, so Paul decided to bulk up on spares (to support future repair requests) and to stop making the DirectStream available for sale. If you can snag one of these for a reasonable price, I suspect you'll enjoy the improvement.
In my case I have the transport connected to the DAC using the I2S interface (an HDMI cable), pairing the two units, so when it's playing an SACD, it outputs pure DSD to the DAC. The sound quality for that, and "regular" CDs is fantastic!
