Marantz SA-10 Vs Esoteric K-05Xs

Here is what the K-03XS manual says about upsampling:

Upconversion setting UPC>***

This setting can be made for each input.

During Super Audio CD playback, the DSD signal is sent as is to the D/A converter without being upconverted.

ORG - (original) The input signal is sent as is to the D/A converter without being upconverted.

2Fs - 32kHz, 44.1kHz and 48kHz sources are upconverted to double values of 64 kHz, 88.2 kHz and 96 kHz, respectively, and then sent to the D/A converter.

4Fs - 32kHz, 44.1kHz, 48kHz, 88.2kHz and 96kHz sources are upconverted to double or quadruple values of 128 kHz, 176.4 kHz or 192 kHz and then sent to the D/A converter.

8Fs - 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz and 192kHz sources are upconverted to double, quadruple or octuple values of 256 kHz, 352.8 kHz or 384 kHz and then sent to the D/A converter.

16Fs - 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz, 352.8kHz and 384kHz sources are upconverted 16, 8, 4 or 2 times to 512 kHz, 705.6 kHz or 768 kHz and then sent to the D/A converter.

DSD - The signal is converted to DSD digital format, and then sent to the D/A converter

So it appears you can not upsample at all, or you can upsample from 2X all the way up to 16X or DSD for each output.

Since it says the upconversion upsample mode is available for each input (except that a SACD is passed through staying at DSD) does it allow for these settings on normal CD playback? (Picture below).

This is from the K-05XS and K-07XS manual download PDF about upconversion.

It says it available by pressing the Mode button on the front of the unit, but it appears there isn't a Model button on the remote. So you can only make these settings on the unit itself? That's a bit inconvenient.

For filtering, it says

Digital filter setting during DSD playback.

DSDF>*** OFF No digital filter is used . ON A digital filter is used .

So it looks like there is only 1 filter available (on). Some players give multiple filters (3-6)

The SA-10 has been replaced by the new Model 10 SA-CD player. Coming in at 75-76 pounds this is a very large and heavy unit. The Model 10 is about half again more expensive  than the SA-10 it is replacing.

@regafan I had seen the newer Marantz Model 10 in several videos and it does look quite nice, but I believe the price is between $12-15K for it.

@fauguy the PCM upconversion cannot be done via the remote only via the mode button on the unit itself so "on the fly" changes aren't possible.  For now I have settled on the 2Fs setting on PCM.  On my player there are 3 filter settings for DSD (SACD) playback.  The cutoff frequency becomes progressively lower from F1 to F2 to F3.  Mine is set on F2.  I think one could get hung up on all the oversampling and filter stuff.  The player sounds wonderful with the native settings.  The new model 10 from Marantz looks interesting and it would be interesting to compare it to my K-03XD which new was discounted to 12K from my dealer.
