Quote: I don't know if that is related to a problem I have been having.  I have 12,000 songs on a NAS connected via WiFi, and I often get this problem at the beginning of a track.  If I use Activity Monitor to check the network activity, the skipping always happens when the the track is...

  Quote:   I don't know why everybody is getting so hot under the collar.  After all, as you point out, this is a science forum, and all I am trying to do is point out areas where science might have something useful to say on the topic, which is, in case we forget, "I don't get why...

  Quote:   The USB spec is concerned with data integrity, and has little or nothing to say about jitter at levels which will have - I think we are agreed - an audible effect in a PCM data stream.

  DaBomb's Quote:   DaBomb's Quote:   Do you not think those two statements are contradictory?  For example, I would claim that one of the audible benefits I perceive of my Nordost USB cable (vs a stock USB 2.0 cable) is an improvement in the precision of the imaging.  Are we...

  Quote: Good!  Progress!    Quote: Yes, I almost agree with that.  When talking about jitter, it is not actually so hard to measure it, and quantify it.  What does represent a challenge, though, is to perform a rigorous analysis of the impact of jitter on a resultant analog...

  Quote: Actually, I am trying to get you to justify that statement.  Because it simply isn't true.  Let me refer you to the Wikipedia page (because it is convenient, not because it is an absolute reference) here.  In the paragraph "Sampling jitter" it states "less than a nanosecond of...

  Quote:   Just how old are you?  Do you remember "Pure Perfect Sound, Forever".  Do you know/remember what the first CD players sounded like back in the '80's before they discovered jitter?  Bits-is-bits-is-bits, they told us.  So, now we have discovered jitter, we understand it, and...

I just wanted to make some observation to share with everyone.   1.  When I installed iTunes 10.4 (under Snow Loepard) BitPerfect went to pieces.  Every track was interrupted by multiple glitches where the playback would instantaneously stop and start.  The higher the bit rate, the more...

  Quote:   I'm not sure that would help here.  You are talking about the cable that connects my PC to my DAC.  I have no way to get the DAC's output back into the computer to digitize and compare.  I suppose I could run a cable with RCA's on one end and and a Mic jack on the other, from...

  Quote:   And not just the power...  The data signal transmitted from a USB port consists of a waveform that the circuitry on the other end is going to try and interpret as a series of ones and zeroes.  If the signal is "clean" then that process should be quite unambiguous.  But if the...

Agentsim, I like the BitPerfect name .   I also like your icon artwork - props to whoever did it - but i miss the little diamonds that were in his original version.  I thought they looked real cool.

Quote: Yeah, I'd like to know how to do that.  My iTunes doesn't have a stop button.  How do I get it to "Stop"?     

I've been using BetterSound for several days now, on a very high-resolution system, and can confirm that BetterSound is in fact very significantly better than Audirvana.  Just thought it was worth mentioning that, since that is the point of the thread.  Good work, agentsim.
