Marantz cd players


Looking for some advice on a possible purchase I’m planning. 
I have been presented with a few good deals on a couple of different Marantz cd players.
1. Is a Marantz sa-10
2. Is a Marantz ki-ruby 
3 is a Marantz sa-30
Looking for the pros and cons and the benefits of each one over the other. 
I am looking at the Marantz brand because I am Familiar with the brand and something I have always had good luck with. 
Thanks for the help/advice

Absolute Sound just came out with a glowing review of the Technics SL-G700M2 by Anthony Cordesman.

There's another one from Twittering Machines that's not as effusive but still positive.

All the best,

Right now you can pick up the Marantz sa-10 for $3500 that’s a $4000 savings so I was really looking at it. But I was able to pick up the Marantz KI-Ruby for just over half it’s normal price of $4000. It was a really hard call to make but I am really enjoying the Ruby. I don’t use the Dac in the Marantz but I have heard it’s a really good one on both the Ruby and the Sa-10. 

I fell in love with the ruby upon first listen. I did no comparisons or shopping; I just bought it. I don’t know if the other players mentioned have this, but I like that the ruby has coax and optical inputs and it’s own volume control.

Love love love my Ruby. Have had it for more than 5 years. Have upgraded everything around it several times but never once had the desire to move on from this player. I also you the DAC everyday via Optical input from both my TV and a bluesound Node 2. 
 

interesting to here the perspective regarding the “house sound”. I find the imaging and separation to be totally engaging - not distanced at all. Definitely curious to hear that technics for informational purposes tho!
