Marantz SA-10 vs SA-KI Ruby

I have the Ruby KI Pearl. I bought it second-hand and did not have to buy it as part of a set.

I don't know how it sounds compared to the SA-10 or the Ruby. The only things I have to compare it to are a Rega Apollo-r (which the Pearl replaced), a Marantz CD6004, and my Oppo players, which include the 105D and the 203. 

It sounds much better than any of them and better than any of my turntables.

These are state of the art transports but they still aren’t nearly as well built as they used to make them.

@d2girls please elaborate !

I can’t speak to a lot of the questions posed, but I have had a Pearl since it was first introduced (serial no 0017!) almost 11 years ago.   Wonderful machine: detailed and dimensional. It replaced an Arcam cd-36. I also have an Oppo 205. Neither of those machines, although they both sound good, come close. I just purchased a Ruby for another system. I should get it next week. I’ll report when appropriate. 

Everyone, stay safe in the pandemic. 

I have not heard the SA-10 but am very happy with my Ruby.  Running 20" IC to the matching PM Ruby integrated, doubt I am giving up much not having the balanced output.  In my mind the Ruby series is a great value.  Love the smooth, detailed, 3D soundstage.  This is a quality piece and a great value.  My only quibble with any of the Marantz gear is the micro display.
