My Denon 1940 has a switch on the front panel that says "Pure Direct". A look in the manual says it is there to be used when the best analog audio is desired, something to do with HDMI being turned off. ..... and maybe the Denon engineers had a poor HDMI design.
Is the HDMI output really disturbing the analog audio? ..... and if it is why have HDMI circuits in an SACD player? .. other than for DVD ... and why would you want video if your interest is superior audio?
Does anyone build a pure SACD player? Maybe Videophiles should switch to Blue Ray and let the luddite audiophiles plod along in the analog world. GRIN. Regards.
I do not think it has anything to do directly with HDMI. It is based on the theory that the video and display circuitry inside the player and/or some AVR/AVPs might cause degradation of the audio. My Oppo player has a Pure Audio setting, but I have yet to hear a discernable difference using it. Personally, I think it may be more of a "feel good" thing, rather than an actual audio advance.
But, you are in a position to know. What are the honest sonic differences using it, trying to avoid any placebo effect?

Placebo effect?
I consider it as being proactive to any internal or external threats.
That said, I do notice a significant difference of SQ in Pure Direct mode.

It may well be equipment dependent, rather than a universal solution.

Looked at a Denon 2900 yesterday and noted a more complex "Pure Direct" switch. Didn't investigate thoroughly but somebody at Denon is "on to something".
As far as my determining subtle "honest sonic differences" I must confess I spent several years of my childhood in/out of B36's, not a good environment for later subtlety in the audio world (GRIN). However, in the interest of science, conversations with progeny and general BS'ing it is a matter for worthy consideration, IMHO. Regards.

The bomber. If there's a bus as large and noisy I'd like to go for a ride ..... my Lord, there is a B36 bus. WOW!! Regards.

Would Pure Direct or Source direct make any difference if my Denon DBP 2012UD is used solely as
a cd/sacd player via analogue outputs? I do not have it attached to a tv or AV amp, nor do I have a HDMI or digital connection attached. I'm not sure I can detect any difference.
So what I'm really getting at is: Would any video signals be in operation in this scenario with potential to affect SQ, while I'm listening to music via analogue to an integrated amp?
I'm inquiring because I prefer to see the track info etc and the Denon RC doesn't seem to work when Pure Direct is on.

IIRC, "Pure Direct" is unique to HDMI. Therefore, it wouldn't work for your configuration.
To verify that, more comprehensive configuration information is available in the user manual which can be downloaded here:

What DSD said.
I use "Pure Direct" mode on my Denon AVR-3310 on ALL 5.1 SA-CD that's played on my Sony BD player. It's great.
...
To update this, I no longer use "Pure Direct" mode for anything, as I failed to realise that the LFE crossover point isn't standardised and is variable per title for any disk of this type. Also, bass management is disabled in "Pure Direct" mode.
FWIW, I upgraded my AVR to the AVR-3313 at the end of that year. Much better machine.
