I own both PS Audio and Ayre products. Note that PS Audio offers an upgrade path from the PerfectWave DAC to DirectStream; it is even user-installable, albeit not cheap. But still a lot less than a new DAC. With the Directstream the upgrade path is much easier as it is done via software to their FPGA chip. Can't beat that! Yeah it would have been nice if they had an interim-step to upgrade the PerfectWave, but a small company needs to make tough choices sometimes about where to focus their limited resources.
