Aside from the Meitner products, does anyone know which (if any) SACD players are DSD from the disc to output, meaning there is no PCM along the way? I just think decoding DSD and then running it through a PCM D to A converter defeats the purpose of DSD.

Allen, how does your originall 940 compare to the early flagships and the latest Sony (and other)players?Assuming same upgrade status.
to the early flagships and the latest Sony (and other)players? Assuming same upgrade status <As we only work on the original SONYs at this time - the Level 4 XB940 actually sounds fabulous, and is very close to the Level 4 DVP-9000ES as covered in the linked reviews on my homepage.
The original flagship SCD-1/777ES at Level 4/4.5 has similar definition but a different flavour, sounding warmer and with a greater feeling of stability, coming I suspect from the massive transport.
We have a tweaked to the max SCD-777ES for the shop reference/demo machine, and I have a Level 4 XB940 at home with no feeling of loosing too much.
The only problem with the XB940 is a poor reliability record for the transports...but we have sourced acceptably priced laser assemblies and are getting involved in teaching ourselves the arcane knowledge of making them all work correctly. Wish us luck!

but ALL subsequent players - SONY or otherwise - use DACs that in one way or another lose the "analogness" of the original pure bitstream format. It's hard to tell exactly what goes on inside these newer DAC chips, but none are bitstream - and very few of the players present them with a differential digital signal (as used in the original SONYs) which I believe (not proven) allows subsequent signal processing to be simplier and hence less sonically offensive.And (again) I repeat - the clock signals in all the lower priced multiformat players is WAY complex! For example, in the 999ES (Page 4-19 in the service manual) the (one) clock chip has a 27MHz xtal connected to two pins and outputs this 27MHz, AS WELL AS three other non harmonically related frequencies.. Tricky - and very hard to get the clock accuracy and lack of jitter that I consider VITAL for great sound.
Our upgrades cost around $1000 which is not beer money - so why not start from a better place?

There are only a few exceptions.
