@ALRAINBOW,
PWD volume is 100% and is connected to my passive preamp which is used for volume control. Sounded great with 241, which I understand was still problematic with some earlier production PWDs. PS AUDIO has removed 241 from their list of previous firmware updates available for download.
Thanks for the advice on the Bridge.

Why do you need an passive amp, when MKII itself has the vol control. An active amp with bass management should have been fine or I am missing something here?

Active or passive. Just analog and not digital.

You can go down to 40/100 on the PWD2 before you start to lose resolution.  That takes into account the noise floor.

More like 80 if you want it all. And no more than 70 or there is loss. Now I am sure it's fine and I am not looking to split hairs. But I did a test to hear it and you can if you use something upstream to control the volume . You loose dynamics not sound tone

it's an integrated amp and I prefer using it and not the PWD for volume control. I don't know what the output voltage from the PWD  fixed @ 100%  is but there's no audible distortion whatsoever with this approach.  It's actually pretty near perfect for my amp. My issue was that I preferred the 241 to the 243 is all.

Thanks for response--I really appreciate the feedback from you guys.

Math is hard I know but the PWD2 volume is .5dB steps, CDs are 16bit, 40/100 is a 5bit drop, noise floor is understood to be roughly 3bit... hence 40/100 is no loss.  Would add that measurements wise the PWD2 measures best in around the 65-70/100 range and drops as you climb.

I do not use math. Besides my ears I read. And if u read on the forums anything below
85 you are loosing bits.

If you read the thread on the PS Audio forum that you replied to in 2013... you'd know better :P

 

Curious did you, at the very least volume match using a metre, when comparing 40/100 and 100/100 using 16bit material?

post #1375 of 1567
Of course I read it. , honestly I tried if at many volumes to hear a change. .was it was recommended by Paul and others to,leave it at 100. Did you read that part ? After reading it I no longer used it and since there was no bypass mode I left if at100. I understood the math and actually read up on it. After reding it I began to wonder about all the various volume controls I was using. At this point I bought a MSB stack and only used the volume in it . It has two sets of analog inputs. . I emailed Paul who said to leave it at 100 . I also use an offramp 5 with it. So your point may be correct but when the owner of a company gives input and he then uses a active preamp with it . And it is set at 100 I did what he suggested. .

So as your point is made was my advise to ask others to listen using other volume controls wrong or correct. Here I will answer for you , doing the math as you say YES It was correct. .

If you are using a pre-amp then yes leave it at 100 assuming it isn't too hot for the pre-amp being used.  But straight to a power amp or powered monitor... 100 is awful loud ;)

 

I run at 70 now that I use iems only because 100 is too hot for the few steps I have to play with on GS-X.

You mean where Paul says...

I am a big fan of using the digital volume control if it is done correctly as ours is. If the system sounds better with a preamp in (as mine does in one sound room, but not the other) it is most likely because of the euphonic additions wrought by the preamp.

 

But like you and Paul say it comes down to user preference.  

post #1378 of 1567
No not preference. People should know
The trials of digital volume attention.
And by the way your good with math so why not help others
Understand what they could be loosing
Instead of trying to prove me wrong.
As whole we are both right but still you are not helping others read here and understand
As users here use the volume control in Foobar or jriver
And there DAC and there integrated amp
All together. Is this correct or do you need me tondo the math
To give you an answer. Help others not me
I am way to far gone to be helped LOL

Relax and let's go listen to some relaxing music

I do not notice any drop in Sq in the 60-100 range on my Kgsshv and sr009s. I was very interested of this for various reasons over several rig combinations, but it was never an issue at all at anything above 60. At low volumes yes, it is very slightly noticeable, that is lower than 40.

Ok cool to know. I did hear things sooner but with speakers and playing loudly .

And thanks for testing it .
