Hello, Steve!
The Droplet is the only Consonance to currently use the Philips. Along those lines, it is the only Consonance player not to have laser assembly worries. The first generation of Droplets used the Sony, and had LOTS of problems. What is interesting is that if you read the review, you can see that even the review sample that won the 6moons.com Blue Moon Award was having issues during the review. Truly a harbinger of the future.
Apart from the Reference 2.0 SACD player which used a Sony SACD assembly (good thing, as I hear the Philips SACD assemblies are as just as horrible as the Sony CD assemblies), the older Consonance players, including the initial iteration of the CD120 Balanced, were Philips. They fail once in a great while. Since they are front loaders with a drawer, once they fail, you have a nice doorstop as the company does not support them. All CD120 Linear players use the Sony CD transport.
