Because i use a externel DAC (Stello DA220 MKII) i have to change volume with the computer.
In my configuration the only slider i can use is the volume slider in XXhighend.
When i use that slider i get a strange and sometimes hard irritating sound when changing volume.
Is that a common issue or has it to do with my config.

I use as primary soundcard a c-media with the open source c-mdia drivers.
Excellent souding!

Hmm ... that sure doesn't look normal to me and you are the first to notice this.
I don't want to blame this driver, but maybe it's an idea to try the original driver ? Just to know whether it makes a difference ?
The being "bit perfect" of the modded driver will be bit perfect for the unmodded version for XXHighEnd anyway (with Engine#3).

Btw, changing the volume in XX would be not different from pressing Pause and Play fast. Does it happen there too ? if yes, you could try to tell me at what "wait rate" things become normal (this could be something well over 1 second then).
Also, if fast Pause/Play vs. slow indeed makes a difference, chances ar high that the driver doesn't shut off the DAC properly.

Lastly, what happens when you press Next during playback ? same problem ?

When i click pause, stop or when changing the volume slider it takes a few seconds or longer for before the action has completed.
Within that time the sound gets often in a sort of mini-loop, sometimes very hard ticks (that scares me..), sometimes silent.

I will try the original C-media drivers, but honestly thats not a good option for me, because i also use the spdif for DD and DTS in my hometheater.

Is there a way to make the volume steps smaller like 1 or 2 db/step?  I don't use upsampling, just 16bit/48khz
Is there a way to use the volume slider with keys, like + and -?

That is what I expected. I can try to do something about that, although I wouldn't be able to test your situation. Let's see ...

I could but it's not for nothing that I do not apply that. Right now all keeps on being bit perfect (mind you, for the "audible" part) ... when I'd do that, it won't. no

Yes, that will be applied in a next version.

So, you'll have some "hot keys" for important functions?  Will they work with play unattended?  I thought you couldn't do that because Play Unattended means only the xxhe eng is working... if hot keys work, won't you have to have player playing ... or some program playing in the background?  (imagine reading my post with a nervous facial tick happening)

The answer is two folded :

1. I think I can manage to apply Volume Change on Engine#3 (Unattendedly running) with Remote Control;
The other "important" functions can -then- be controlled by itself similarly, but coincidentally what it takes to really apply it is more difficult than with the volume control.

2. When XXHighEnd is brought up during UnAttended Play, I sure will be able to change the Volume and in fact all of the other stuff.
The point here is that it takes the knowledge of where (time position) XXEngine3 is playing, so playing can commence where it left off.

Peter,

I doubt about putting a passive pre-amp between DAC and AMP. Volume by pc is a bit risky.
But is that a step back in quality?

Are the next setup's equal in sound quality you think?
1. XXHighend>Volume slider at   0 db>Passive -18db (resistors)>AMP
2. XXhighend>Volume slider at -18db>AMP

Allow me to first extend the list with one other option :

1. XXHighEnd>Volume slider at   0 db>Passive -18db (resistors)>AMP
2. XXHighEnd>Volume slider at -18db>AMP
3. XXHighEnd>volume slider at -18dB>Passive 0 dB>AMP

When you are afraid for the 2nd option you can always use the 3rd. I know, it is the most peculiar way of doing things and I don't think you will find anyone stating the same, but I say it is better. Just give it a listen (and A-B with the 1st option !) but keep in mind the noise the preamp may (or will) add with the 3rd option.
Might you agree with me and you find the 3rd option better indeed, you can always go for the 2nd option at the time you got used to all and are confident that the "emergency" volume knob of the preamp is not needed.

The 2nd option, or IOW eliminating the preamp, will give you the best transients your system can unveil, BUT, now you are fully dependent on the AMP and DAC. Thus, any "smoothing" the preamp will apply otherwise, now will not be there, and e.g. harshness of AMP or DAC will show, if there. In that case, do not think your preamp made the sound better ... it only masked bad things from the rest of the chain. yes
Without the preamp (passive or not) the sound will be totally different ... that's a guarantee !

Yes, i experienced in the past that a passive preamp gives a little change in sound. Like you say it's a like a smoothing effect.
On the other side i have read on another forum that digital volume reduction gives less bit-dept?
Can you agree that (in theory)?

And if, what effect should thiss have on sound quality. Less dynamics, bigger noise floor?

I think you can find some answers in this post (from 09.U-0a setup with external USB DAC).

Quote
And if, what effect should thiss have on sound quality. Less dynamics, bigger noise floor?

Less dynamics is what everybody would say. This is stupid theory though (IMO), because *or* you are not able to hear the full range, *or* -when you think you do- you will hear distortion at the low end instead.

Just try it with XX which very officially presents you the attenuation in dB. Take a 16 bit random file, set XX to -0dB, the preamp to any volume you think is bearable. After this, set XX to -90dB. Officially one bit is left now, and no music can come from it (and no dither is applied). However, when you are able to hear it, you'll hear it as distortion. Now, can you hear anything ?
Keep in mind, the volume of the preamp should be kept at bearable listenin levels !

My suggestion is : no. You can't hear it.
So now tune up XX until you start hearing something. Ok, in the before you obviously were with your head in the speaker, but keep in mind this is not much realistic for obtaining "dynamic range". So better step back to the listening position, and find out when you are starting to hear music at tuning up XX' volume.

Say your answer is -66dB. This would mean that the dynamic range you can obtain is ... well, 66dB. Keep in mind that the 0dB is the "bearable level !".
Sidenote : "bearable" might be 105dB SPL (listening position !). So what you -in my example- actually still can hear is 110 - 66 = 39dB.
With -66dB you'd have lost 11 bits so 7 remaining. Way too few for good music. But *now* you'd have to search for music that allows playback at 105dB SPL *and* has music information at -66dB. Of course this exists but it will be more rare.

A bit depending on the outcome (and your system), you can imagine what happens with a 24 bits DAC. This means 144dB so called dynamic range, and there is NO WAY to unveil it.


The noise floor too, IMO is a phenomenon which does exist in theory, but in practice works out slightly different.
My point would be this (disclaimer : by lack of real signal process knowledge, haha) :

In a DAC there is nothing like analogue noise with will show underneath its capabilities. That is, not derived from the digital capabilities (from the analogue output stage there is, but this is not about the "noise floor" as we speak about it). You must look at this relatively :

When a 24 bit DAC is fed with 16 bit material derived from a 24 bit file (like you can do now since 0.9u-2) the cut bits will create noiSES. This is nothing else but harmonic distortion occurring at a certain level, and that level will be just around the noise floor of 16 bits.
Now here we go again : the noise floor of 16 bits would be -96dB, and I think in the above we determined that there is no way that you can hear that. The dynamic range you'd need to obtain it, is too large.

The same noiSES will appear when you feed a 16 bit DAC (or any bit DAC for that matter) with, say, 12 bit material derived from a 16 bit file. Again, the relativeness is important, because again the *cut* bits will create noiSES, or better, the remaining 12 bits actually needing the 16 bits will do. So the noiSES floor is 12 bits, and this is -66dB. See the story above. Happy

What actually happens ?
A more fluent sine is cut into more square cutoffs because there's not enough bits anymore to keep it as smooth as it was. It is those squares causing the harmonic distortion, or maybe better : squares have a signature of over tones that don't belong to sines.
A side effect of squares is that they bear more energy than sines. And this is why this "distortion" can be audible above the noise floor. They *will* be when the needed attenuation is so large - and which follows from too much gain - that they're in the audible level.

swoon


PS: for fun, look at a 24 bit file opposed to a 16 bit file. When you follow my reasoning, you'd conclude that a 16 bit file is full of (relative) harmonic distortion opposed to the 24 bit file. The sine in the 24 bit file is rather endlessly more smooth opposed to the 16 bit file.
Now, who says - or what determines whether only 24 bits is good enough, 16 bits can do fine, or 14 bits are okay just the same ?
The dynamic range you can perceive does !
Now I think you can better understand why I said in the Releasenotes of 0.9u-2 that to my theories you wouldn't hear the difference between a 24 bit file played as such, and the same 24 bit file cut to 16 bits (when played with XX Happy).

Peter plz fix the volume issue on eng#3.
I was just listening at -18db, switched from song and there was a huge crack (0db!!) in my speakers!
Thats bad for my speakers... and my heart.

I hope you can do something about that, because nothing beats eng#3. Excellent sound!

Hi
Yesterday I heard a loud crack also.  I have my vol. set to 0.  I thought maybe it was some weird electrical problem?  I do know it happened to me after playing/stopping/clearing/ many albums kinda fast for me in a row.... after the crack, i rebooted, I don't think it's happened again, but I've also been far out of the room with stuff going on.  Hmm I was thinking maybe it was my tubes. Nothing in eng3 changed from .9U1 to .9U2? What about the players influences before it disappears?

I pretty much listen exclusively using Unattended playback

It happens so now and then when i click start to play a song. Its just random.
I think that it has nothing to do with your tubes or whatelse, its XXhighend.

I don't use XXhihgend now anymore till Peter can do something about that volume issue.
Foobar with directsound in vista plays as nice as eng#1. Maybe a litttle difference, but i can't hear it.
I love Eng#3, so ill wait   smile

Peter, is it difficult programming for you to avoid any thicks, cracks on eng#3?

Guys,

I am not sure what you are experiencing. Anyway apologizes, really !

a. I think with the new way of assigning the DAC (that avoiding rejections by Vista) things have changed. However, I myself never noticed that at 44.1/16 playback (which should be Dave's situation).

b. When the format of the file has changed there should be a hold on the next file's playback and a message as how the Releasenotes on 0.9u-0 (I think) announces. Tonight I witnessed (outside, doors closed) the family jumping at the sealing because the format change wasn't captured anyay.

I'm really really sorry, and I guess testing of all the combinations (of changes) takes ages to test thouroughly.

Its just random.

That's what I noticed too, assuming the max level "tick !" which -no matter how prepared you are- drops you of your chair. This would be #a above. #b is even worse because it lasts (a few seconds ?).

Please note that -so far- all came to me at changing from 44.1 to 88.2 or 96, so it seemed relatively rare. However, what Dave claims is that it can happen, say, always.

Btw, I checked for this earlier today, and it happens in the DAC, not in the (SPDIF passthru) soundcard.

Possibly this was happening always, but was attenuated by the analogue volume ??

Well, it's only happened once, yesterday, and I still don't know really where it came from.  It happened while a song was playing, not while pushing buttons.  I haven't heard it since.  I've been stressing the player today a bit too by changing Q1 settings and everything is very stable. (I still like my Q1 18 setting over the -2 invert i heard today... hope people don't underestimate playing with the Q1 to match their system... and no we are assured it's not equalization...don't ban me for saying that word heh.

edit
hey too, maybe it happened after i was doing some "Dac Test"s...then listening to music... i think?
