What is going on here?
The following pics are what we called once the FAKE PCM63 chips!! http://www.diyaudio.com/forums/showthread.php?postid=1366048#post1366048

Hard to believe, but the FAKE chips - are back! Who would have think that we will see them here ever again?!
Be carefull! Not all the chips are genuine BB !!!!!!!!!!!!!!!!
BTW, they MIGHT sound: I have one very good pair of them (!), but several other of them which I was trying DID NOT SOUND.
a'af, putting the url of BB might well discredit the rest of your reputation here.

: DDDDDD .... i have nothin to say about the dramma but had a good laugh nevertheless, thanks guys.
IJ,
how much you pay for your DA8X? I believe if you sell all your KY chips, you will make lots of money and also your KY is 100% sure original part. Just simple maths. If you really need money, put back 63P and resell your DA8X in the market.
Just joking!!!

Hi Spencer!
Good to hear from you!
You know that I am not a dealer... BTW, I don't have the DA8X: Manfred has both of them now (2 DA8X = 16 KY chips (...)) but he will never sell them, that I can tell you for sure.
Greetings!

Wait, wait! Dramas can start small and become very big sometime later. Or the other way arround...
Be aware that the "Y" chip that a´af is trying to sell this time might well be a genuine BB.
All that one has to do is to forget the past.... However, this is not always easy to do, or recommended.

Y vs KY
Hi Irgendjemand.
I have a ballanced digital section with two PCM63 in each channel, so comparing individual chips would be complicated.
Listening some more to the difference between the Y and the KY, I think I must retract that the Y has more output than the KY.
I would rather put it as: the Y has more energy at the high frequencies.
The KY seems more relaxed or softer but without loosing much if any informations.
I am not shure if the Y can be be said to be more realistic/extended or be acused of distorting more or differently?
In my setup the KY sounds more pleasent but maybe less present?
I dont relly know.
I am happy I have both.
Maybe I will get more insight if I change something else in my setup.
Regards
Erik

Fascinating!
Hi Erik,
Your lovely post strongly coincide with my own discoveries. In a sense I would say that we are listening to music the very same way!
Firstly, I agree that the KY seems more relaxed or softer in relation to the “Y”, somehow without loosing much if any information. It is indeed less present – this is also my main impression.
Can the “Y” be said to be more realistic/extended? What we have in common is that (also in my setting) the KY sounds a bit less present.
This however brings us to a very interesting point: Where is the true?
Similarly to your discoveries, but not changing between Y and KY, I am frequently exchanging my Digital Filter IC, from SM5842APT to DF1704 and back. The differences: The DF1704 is more realistic, while the SM5842APT is more… pleasant but also less present. Sound familier, isn't it ?!.
On this very very high Hi-End level, this become terribly hard to correct, if at all needed. I came to a situation where I can’t give up on the realistic sound of the “Y” – but then, I am TRYING to relax myself a bit by listening to the SM Filter… it does not always help... so personally I am much using the “double” realistic setting: DF1704 + “Y”.
Few days ago I wrote to Herb: “You know what, I was much busy with the DF topic myself: So I am using again the DF1704 in my AVM DAC (instead of the SM5842APT): The sound differences is that with the SM5842 it is indeed beautifully resonating, but - I am afraid it is not realistic ???? , while the DF1704 is far from being beautiful, but is at least closer to the truth”.
Herb answer was remarkable: “Do you have recordings which are 'far from being beautiful'? I cannot understand this. To me: "less beautiful" = "less realistic"........”
Hmmmmm…. Another thing to think about… I wish it would be THE true...

As far as all this thread participants are interested in PCM63P-K, probably some of participants have accomplished (or are aware of) these or those DAC measurements. I'm interested in output impedance (value, dependency from level and frequency). Well, I know datasheet numbers 🙂

Who is interested in PCM63P-K???? Hmmmm... did you read through the thread?
"K" is not such a great chip; may be "K2"

How about KY or Y? 😉.
Ok, consider my question regardless grade/letter-classification.irgendjemand said:

An externally hosted image should be here but it was not working when we last tested it.
PCM63P-KY form YAMAHA,see photo~

Hahahahaha . that means plain Y is lower value than KY, maybe lower than K.
Guys I have a profesionnally built d1v3 for 750 usd with plain pcm63p . Output cap philips MKC. Very good q components overall.
