post #406 of 498

For the first time, I had an optical cable fail on me tonight. The sound from my sound card had been cutting out, but I blamed it on intermitent software or DSP problems in either the card or receiver. Well, today it started cutting out every few seconds, driving me mad, so I started heavy duty trouble shooting. Long story short, when I replaced the bad optical cable with another one I had, everything streamed great again. The bad wire still glowed red at its tip, but somehow or another wasn't transferring the data correctly (probably a bend in the wire somewhere that caused damage). I did not lose dynamics, or clarity in the mid range. Bass did not become flabby... it just went from sounding great to dead freaking silent. It reaffirms the fact that when a digital cable like USB or optical is bad... there isn't any sound. When its good... there is sound. Its simple as that.The cheap optical cable that broke was a cruddy belkin one. The one it was replaced with was from monoprice, built like a tank, and cheap as dirt. Anyway, thought I'd share my experiences.

Yeah. Errors usually result in plainly audible and sometimes quite annoying glitches.

 

To those saying that bits can flip.. well yeah, the most significant bit is as likely to flip as the least significant, the former causing huge distortions (worst case are clicks/pops) to the waveform.

I found a nice PM in my inbox when I got back from my "involuntary vacation" from HeadFi. I thought I'd share it. It really made my day...

 

Hi BigShot,

 

I just want to say thank you for your honest and objective comments at Headfi. I did some careful research myself and have to agree with most of your comments.

For example, I also came to the following conclusions:
1) human ears are usually the limiting factor in "Hifi";
2) 256 AAC VBR is good enough for music listening by most (if not all) human ears;
3) most, if not all, "hi-end" DACs are overkill for music listening.

I am glad that Headfi still has you around. Thanks to your posts, I learned and saved a lot. Now I realize that I made quite some mistakes before. Shame on myself; I have a PhD in science but have not investigated those audiophile myths objectively until a year ago (I probably even propelled some groundless claims before).

Welcome back!

 

The oddity is that the "objective" Head-Fi crowd is actually fairly diverse in terms of prior education and experience. As an "SS" consensus emerges I see it as proof of a common pragmatism.

 

Bigshot, I think a lot of people have a respect for your experience and a willingness to share what you've learned in a simple and straightforward manner. But then there is also another contingent of contributors...

Who knows? If Caesar gives me thumbs down again, I may be forced to join the lions in the colosseum again. But that's OK because a bad penny keeps turning up, doesn't it?

 

(I love mixed metaphors!)

Welcome back!  

 

I did notice your absence, glad it was only "virtual", and sorry it was involuntary.  Always best to move forward.

 

And always remember, you can lead a gift horse to water, but you can't look him in the mouth.

Welcome back, bigshot. You were missed, and it's great to see your banning wasn't permanent.

Thanks youbee!

 

...and I still dare anyone to hear a difference between AAC 320 and lossless at a normal listening volume and EQ curve! I've never seen it done.

I'd guess many people would say they could hear a difference because hearing, of anything, is very subjective. There are clearly measurable differences in bit rates and stuff like that, but are the differences such that normal hearing people can discern them?

 

How do I determine what someone else is hearing (and I'm an objectivist)?

A recent thread here has led me to an epiphany. I realized that people who consider themselves "subjectivists" are probably more sensitive than other people. They feel things more strongly and that is why our discussions of "sound science" make them lash out. They're in pain, but all they really want is to be allowed to "own" their subjective belief. I'm fine with that. Everyone doesn't have to be a "sound science" person. Everyone doesn't have to agree. I'm going to make a point to give them the gentle reinforcement that the things they believe are OK. I think we could all get along better if we were more accepting of different belief systems.

I think it's worth a try at least.
