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.
