Marantz Reference Series Laser Replacements

I am wondering if anyone with a Marantz SA11S3, SA-10, or SA-KI Ruby has needed to have their laser mechanisms replaced. These three players all use the same laser mechanism. The SA11S3 and the SA-10 are older players at 8-10 years, depending on time of purchase, and may be getting low sacd laser outputs by now.

Early generation Marantz sacd players were almost all well known for laser failures and short laser life. The new Marantz players seem to be much better in this regard. 

While I have not noticed any threads on forums about laser replacements for these particular players, that does not mean someone has not had an issue.

Just wondering......

I have a SA-KI Ruby player and I track the laser times and outputs, which is available in the Service Modes of the player. But I have no idea of expected laser expectancy.

And now with the double sale of Marantz from D&M to Sound United and then to Masimo, there is the whole Marantz Service networks reorganization. 

I live in Australia and Marantz service is a reorganization in progress at the moment.
