Sony KHM-234AAA vs. KHM-234ASAA?

[SA Audiophile]

My Shanling SCD-T200 uses a Sony KHM-234AAA transport, but I can only find a KHM-234ASAA listed locally and internationally.

Is there anyone out there who has perhaps compared these two? Are they different, or is the 234ASAA just a newer version of the 234AAA?

Something else - the Shanling SCD-T200C uses a KHM-280AAA transport. It should fit into my machine, but would it actually work, or is the servo board of the SCD-T200C different from that of the SCD-T200?

i ordered for my t200 the asaa and works fine but sacd is a pain sometimes i need 2-3 restart with the cd to get it running. but didnt know how it was before, i bought it with the transport defect.
