I agree with all the opinions. Thanks!
About SONY Transports:
Models CDP-XA7ES, SCD-777ES and SCD-1 use a floating suspension chamber-transport mechanism with a brass weight securing the disk in place. The optical group is fixed, the disk moves (and spins).
Now, more recent models SCD-XA777ES and SCD-XA9000ES use a different mechanism (without the brass weight). But the catalog description says the optical group is also fixed.
Is this transport better? DO you know how it works?
