Sony DVP9000ES as a Redbook Transport?

If you haven't already check out Empirical Audio. He seems to do alot of what you're after.

In theory all transports should be the same,
however in real life there are some differences, which make them sound different. To name a few: Jitter, Power supply noise, error correction algorithm, etc.....
The lack of detailes and poor soundstage probably caused by a jitter on SPDIF output.
Properly designed external DAC can help significantly.

I currently have a Sony DVP9000ES and an Arcam FMJ 23.Both
are being run into a Benchmark DAC 1.I am purchasing a
Denon 3930CI. I plan on keeping the Sony or the Arcam. Any suggestions on which one to keep.Currently I use a Toslink from the 9000ES to the Benchmark and a D-60 coax from the Arcam to the Benchmark. ???
