Perfect Wave DAC Owner Unite - Page 92

post #1366 of 1462

I'm a new PWD MKII owner. The PWD was furnished with firmware v 2.4.1, which sounded great. But eventually I updated to 2.4.3 as recommended by PS Audio, which IMO is a downgrade in sound quality. Anyone else here have similar experience? Thanks.

Hello I own the Pwd mkii. I use 243. But I use an offramp on one of I2S Inputs. It sounds pretty good.
Do you have a bridge inside the unit. ?

I don't have the bridge. I'm using USB input only for now. I was hesitant in buying the bridge after reading about the problems others were having with its implementation. Thanks.

If you do not own a bridge do not buy one. , at some point in the future they will have a bridge 2 and hopefully this one will be fine.

Now I did read that the Pwd sounds better with the bridge inside but not using it. As I do not have one I cannot comment. I am using the 243 and that is what has been shipping with the dac. Also how do you connect it to your amp.
How is the volume control being implemented in your system.

I am new owner of PWD MKII too, got it just few days back. Using it USB->MKII_>Emo UPA-200 (power amp)->HE-6, and it sounds great. I need do EQ a bit, but I am happy with it.

 

I am wondering if I am missing an Premap, not sure if the output volts from MKII RCA output is ideal match for power amps which has input sensitivity of 1.1 V (for full output; 8 ohms).  I have read that output volts of MKII can be change using remote, but not sure how to do that. 

 

Please suggest if I can change the output volts on MKII, if yes what should be appropriate output volts.

@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 #1380 of 1462
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. .
