Marantz got back to me this morning. This was their reply.
lo Robert,
Thank you for contacting Marantz Support, we value you as a customer and appreciate the opportunity to be of assistance!
My name is Jim. I am the Tier 2 Technical Support Lead for Marantz. I understand that you have an SA-KI Ruby and you are trying to determine whether the warranty is for three or five years.
Technically it is both. Marantz reference level products, by default have a five year warranty. And the SA-KI Ruby is a reference level product. However, there is clause in the warranty that states that for Super Audio CD players;
"
-
Optical Pick-ups and/or CD-Drive Mechanisms are only warranted for 3 years. After that time, Marantz will reimburse for the labor required to replace the part for the remaining duration of the 5 year warranty. The customer will be responsible for the actual cost of the part.
-
All other components are covered for both parts and labor for the 5 year period.
"
So for the unit itself and most parts and labor the warranty period is five years. For the optical pick-up and CD-drive mechanism specifically, the warranty is three years.
If you have any further questions please feel free to contact us again.
Thank you for contacting Marantz Customer Support. Have a great day!
Warm Regards,
Jim

So it looks like the warranty is 5 and 3. I feel a whole lot better.
