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!

Had an SA-10 when they first came out and loved it.  At the time many of the Sony execs owned them.  All good until it quit... as almost any mechanical item might when it wears out.  No parts available and big money to repair.  Not wanting to spend the money for the SA-15 for a system I now seldom use; as I mostly stream with a dCS Bartok. I replaced it with the N30 to have the ability to play my SACDs.  It's DAC is very nice for those discs... a mostly Japanese talent.  For CDs, I output the N30 via SPIDIF to the Bartok for decoding.
