Here is an explanation -as far as possible- of the various Q parameter settings.
Q1 - Good old DAC influencerIs there since August 13 2007.
Influences incoming jitter at the DAC and the analogue side of the DAC.
Generally a lower setting makes the sound more -as perceived- "accurate" while a too low setting may let music sound too thinny.
The outgoing data stays 100% the same as the source ("bit perfect"). Of course this is outside bit mangling stuff like upsampling.
Q2 - Is believed (!) to influence outgoing jitter.Is, together with Q3, Q4 and Q5 there since Januari 25 2009 in 0.9w-9, and the main controlling phenomenon for Q3, Q4, Q5. Again all "bit perfect".
With Q2 at 0, nothing changes opposed to Q1 alone.
Q2 (and the others) emerged from pure theory and the experience of a few years people reporting about
unintended SQ changes. Thus, from the experience and learning what happened at these unintended SQ changes, now an explicit parameter is there for influencing SQ in "that" area.
The higher the setting of Q2, the higher the influence will be, although certain settings may cancel out like the cancelling waves (opposed to standing waves). Similarly, a certain setting may add up exponentially (like standing waves).
When the Q3, Q4 and Q5 parameters are left at 0, Q2 still influences, though the most mildly.
Watch out though : Even with Q2 at 1 (the lowest zetting when active) this is exactly what could happen at an unexpected SQ change.
Q3 - Dictates the interval Q2 should to its jobBtw, the exact job of Q2 remains a ...
.
This "interval" is not about some rational thing, but the higher the slider, the more Q2 becomes active.
Q4 - The strongness of the influenceThe higher the number, the stronger the influence of Q2. So note that in combination with Q3, the stronger influence happens at smaller intervals.
Keep in mind : this is just influence, and nothing like increasing sound quality. Whether SQ increases or decreases depends largely on your computer system. Also, what aspect of SQ changes is also dependent on your system.
Note : The 0 setting still influences !
Q5 - Resonating the influenceWhere Q2 acts upon request of Q3 with a strength of Q4, Q5 varies Q3. In other words : the way this is setup allows that the influence can "resonate" upon itself. You can see it so that Q3 is varied by the amount of Q5.
Careful : This red text does not indicate danger, but the importance of this Q5 parameter. Example :
When Q2 is set very low this means that the influence is low. However, think in higher level frequency here. The lower the amount of influence (and this works together with Q3) and the higher the force (which is Q4) the slower the resonance will occur, and the longer it will last. THIS MAY IMPLY AUDIBLE SQ CHANGES THROUGHOUT TIME (meaning each 5 or 10 (or who knows) seconds a change in SQ. Of course this is the most wrong thing to happen. Therefore generally you could say that the higher Q2 and the higher Q5 the more frequent the resonances will occur and the shorter they will last. The main factor here is Q2 itself, and e.g. a Q2 setting of 3 with an Q5 setting of 30 won't help much at avoiding "bad" resonances.
Also, a Q5 of 0 won't help, because the resonances are inherently there.
This too is just theory so far, and might you find an "uneven" SQ at certain intervals which you can't solve, the best solution would be not to use Q2 at all (nothing operates then)
or set Q2 at 1 and work only with higher settings of Q3 plus Q4 to your likings.
Lastly : At the moment of writing this, not one single second listening to the results has happened. In other words, the working has been tested to be without errors (this can - and did happen without sound), so it is pure stupid theory as said above;
From here on "we" will start to learn whether theories may become practice. When nobody can perceive any difference (and watch out for the placebo pills !) theories are proved wrong, and at least this means of influencing will be removed out of XXHighEnd again. But :
This then just proves theories are wrong, knowing that unintended SQ changes happen, and it will be a matter of better analyzing what happened in between such unintended SQ changes. But that is for later. Maybe ...
