Title: Problem with DDDAC solved with 0.9m-1
Post by: hal3101 on October 12, 2007, 09:53:04 am
Problem with ticks and noise with DDDAC and Q1 solved with this version. The sound is incredible clean and airy. I am now able to set the q1 to -3 and -4 without ticks and noise. With the older versions I had some problems with noise even at 20 on q1.

Interesting ...

I'd say the only reason can be CPU useage ... but then very specific. I would never had suggested that this could be a problem for Q1 values, although thechnically it would be true.

I assume you have normal (total !) cpu useage of, say, 3 % during playback, with 0% in the "XX Core" ?

Btw, I only now see that you are talking about 0.9m-1 and not about 0.9m ... is that correct, or do you actually mean 0.9m ?

Well for me 0.9m-1 is better than 0.9m.  For the same albums I would hear "record sounding" pops & clicks when at Q1 -3 invert, I hear none now.  Also, I always used to hear a glitch/tick/crackle when my laptop video display would turn on/off with 0.9m... (again only with Q1 -3 ... not at Q1 13;  only two settings I've played with much) (my display turns off after 1 min of no use): With 0.9m-1 no glitch/tick/crackle when display goes on/off... none at all.

Going to venture back to Q1 -4 (where pops/ticks were even worse with 0.9m) and try that with 0.9m-1.

Dare I say without going back and forth that I think 0.9m-1 sounds better to me than even 0.9m on my setup....haven't had the time but my body tells me so... at least no pops/ticks.

and yippi ki yea
Q1 -4 invert without a hitch... and sounds just a touch better, I think, than -3 (Beethoven piano sonatas & Uncle Earl bluegrass stuff) will listen closer later tonight, but things just keep getting better... is it possible
 yeehaw

EDIT (hmm late at night listening)
hmm went back to -3 for some albums tonight... bass hitting harder/better at -3; dynamics a bit more natural, not exaggerated... probably all album dependent.  went to -2 briefly, then back to -3.... over the long haul here I'll need to venture about the Q1 slider. 
Edit: 10/14/07
I ran XXHE about 12 hours yesterday.  Did some next/prev/seeker bar draging/changing Q1/invert&uninvert (heh, what's the correct term) and never ran into a glitch/stall/freeze... I don't click on things overly fast though.

Is there still talk of adding finer gradations to the 0 to -4 area?  Something like this possible?---> Find an area you like (any area) then click on an option that lets you work in smaller gradations around that area.  Example.  Say you like area Q1 13... click/check mark while at 13 and that would then change things to allow you to move another slider up and down from say 12.0, 12.1, 12.2, .... 13.8, 13.9, 14.0 ?

I am using the DDDAC1543 and for me the lowest Q1 = 20 in version 0.9m-1. Lower values give cracks in the sound!

Do you use the MK2 version of the DDDAC1543?

Regards,

Johan

Hi Johan

I am not familiar with your DAC neither I am a digital expert.

However I remember that the XX first introduction of the Q1 being able to pass into the minus area had a lower -4, meaning the -4 we have today is equal to the older -2.
The former Q1 set at -4 made my FireFace freak completely and closed Vista.

Now I can't help thinking that you not being able to go lower than +20 could have something to do with your DACs internal USB to SPDIF conversion? Some eletronics does that job. And here might be something that prevents you to go lower?

There are some people who choose this device to bypass their DACs internal simple electronic USB to SPDIF converters, but I have no experience if it's better.

Yep, still planned. Also about extending the slider to below -4.
I've already been working on it, but technically it is not so easy because of running into (clock) stability issues. I think it can be done though, but it takes time to find the best way.
Why do you need "twice as good" each and every week anyway ? :biglol:

Talking about the 0.9m-1 version. I have not tested the 0.9m version yet. Normal cpu usage. 5-6 % one one core and almost 0 on the other.

I am using mk2 version of the DDDAC1543.

I have not been able to trigger any cracks or clicks with this version yet at any settings on the Q1 slider.

Which buttons do you push to find the screen with CPU usage  :blush1: :blush1: :blush2: :blush2:

Select the buttons <Ctrl>+<Alt>+<Del>
Select  option Taskmanagement,  tab "Performance"

I have a dutch  version of Vista, so the translation could be not 100% ok
