Marantz SA-10 vs SA-KI Ruby

Hi all,

wondering if anyone one can explain what makes the difference in these 2 players? (Other than balanced outputs on the SA-10). 

MSRP difference is $2k...

Do people think they should sound the same?

SA-10 spec sheet

SA-KI Ruby spec sheet

Curious - what do you think? Electrical engineers, how do the insides compare?

How do the claimed specs compare?

I do believe the KI "pearl" is a special LIMITED EDITION. They only made like 500 of them and sold only in EU. And they were sold as a set only.Go head and FIND ONE for sale from any dealer in the USA. I guarantee you cannot.  
Those are the only things that matter.
@elizabeth ??? Only things that matter ???

I tried buying the SA-KI Ruby for my second system (single-ended) but in my country they are only sold as pair with PM-KI Ruby.  My regular hi-fi shop suggested I should get another SA-10 since the actual retail price is a lot lower than the list price.  The Ruby being limited edition, need to pay at list price or even higher.
@elizabeth @anwar ICIC

The SA-KI ruby is now available for purchase as an individual component. 

Could you tell me, what is the retail price of the SA-10?

And back to my original question, they seem to have the same transport and same DAC and same filtering tech - are they the same player?
My bad. Yes the Ruby SA-KI is available. It is most likely the same item as the limited edition Pearl was in the UK.What is the difference? $3999 to $6,999? $3,000. Easy.   
The Sa-10 has some better part from looking at Googled images of the innards. The back is the same with the KI only lacking the balanced outputs. Inside the 10 hs shielding the KI lacks. Plus the main board on the right is very different. The 10 has big heatsinks in the middle, lacking on the KI.
(the Sony SCD1 vs the SCD777 when introduced was sort of the same. they really were very similar, the price. $5K vs $3,5K, then $2.5K for the 777 as they sold off the remainders.
But does it use the same processor (DAC)?
twoleftears sez: " But does it use the same processor (DAC)? "Ahhh the million dollar question!            
Need some reviewer who has both, or Marantz advert to answer.Advertisements say the KI uses the MMM  decoding. Which is the same sort as in the SA-10. Whether it is IDENTICAL???  
The remote sure looks the same. The case is nearly identical. Only the lack of balanced out on the KI Ruby.
I spoke to my local Marantz Dealer, he has the Marantz SA-KI Ruby on display.   
The shipping wt. of the SA-KI Ruby is 37.7 lb The SA-10 is 40.57 lbSO you are paying $1000 a pound for whatever extra is inside the SA-10
Lol @elizabeth I saw that as well. Did he say anything about the sound?
No . I asked him if he had one. That is about it. Actually I called him about a Bryston BP1.5 Phono box I am getting repaired. The Marantz was a side question. I suppose I could ask him to loan it to me. But since I have no plans on buying one, even as a spare hah hah,, I would feel not right just to ask so I can blog about the sound.I get too much pressure from a few folks that 'I do not do enough' to do a review of the SA-10. I am NOT a reviewer. And I would absolutely feel the need to compare to other equal devices. Something I cannot do. So no way can I say this is better....Plus when I say yeah my $40 five disc changers (I now have collected 7 working, and a few spares) via the Marantz sounds blah blah.. Who's gonna believe me anyway. LOL
The Ruby versions probably have some better parts and implementation than the standard versions, much like my Marantz PM-15S2b has over the PM-15S2 or S1. In my case, Ken Ishiwata took some of what he did with the Pearl series (also limited to 500 units each) and applied them to the PM-15S2b.

Whether it sounds better, I can't say, but they are in demand.

All the best,
Welp, I did it. I bought one last night. Should come next week I think. 

(Ayayaya i can’t believe i just purchased something so expensive, smh lol)
Tell us what you think after giving it some time

Looking forward in reading your report on this spinner.  Happy Listening!

You are tops in my book. Looking forward in reading more about your SA-10.   Happy Listening!
@leemaze Which one did you buy?  The '10 or the 'K1?
 @twoleftears Bought the KI. So far sounds lovely. Will compare it to my Resolution Audio in a couple weeks. 

Off the bat though, running an airport express to its optical input sounds fantastic. 
Thanks for that. You inspired me to run my iPhone pandora through audio engine Bluetooth to KI dac via optical. Huge improvement over rca out from audio engine to amp. 

It's been 14 days and somewhere between 100-150 hours and the SA-KI Ruby has really started singing.  It's silky smooth sounding with super detail.

I have to say my 15 year old Resolution Audio CD50 holds up really well in comparison - nearly as sweet and "analog" in the mids - just as detailed.  But the Ruby has just started presenting a lot more 3-dimensionality between the instruments and it's starting to pull ahead.  To be continued...
Thank You for the follow up. Looking forward in reading more impressions from you.  What other gear including cabling is in your system?
Happy Listening!
I, too have wondered how the KI Peal would sound, compete with the SA-10 or KI Ruby? I know that the Pearl is an older design/machine.
Happy Listening!
