Schiit Bifrost Uber Analog Upgrade - Page 43

Of course, not being able to hear above 15khz myself, I still feel pretty secure with a sampling rate of 44.1khz.

 


 

Yeh, I didn't really want to escalate the situation and turn it into a firestorm. I understand the engineering half of it but I know a huge amount less about the human side, it would be ever so foolish to engage in a debate on something I'm not expert in.

 

To be fair for most purposes 44.1khz is probably fine. The only place it bothers me is classical music where the upper harmonics are of such a higher importance. It's made worse for me that I personally have a very high upper frequency hearing threshold, I can hear up to ~21Khz. Combination of being on the upper end of the bell curve and being in my twenties! As a physicist my mind is always more inclinded to taking a thoery and shaking it by the throat to see what falls out :evil:

21kHz,dang you must hang upside down and Schiit on the floor of caves. :D A little Bat humor.

I used to be able to make it to 20 kHz when I was young, nowadays I can still hear just over 17 kHz which is probably much more than I should at my age.

IMO to a large extent, there's a lot of imaginative claims about what they can discern about sample rates and resolutions best fitted for lab equipment. For now, I'll leave it alone. Till someone starts up again.:veryevil:

Yes, and really enjoying the Uber. I also bought the USB board, so I'll have more options if there's an underlying problem on the optical front...

In the meantime Amazon keeps having problems getting me my Bifrost. Each time they give me a gift reward that I can only redeem for limited merchandise. At this rate, any more and I'm going to insist on shares of preferred stock.

Anyway, this is why I bought direct from Schiit.  Of couse, the massive ice storm has really delayed things, and I'm not sure if I will get it today or tomorrow.

Same weather same FedEx same problems for me. I'll have to be patient, I have no other choice.

Just got the update that my delivery is due tomorrow. I guess one more day won't hurt.

Lucky you. :D

Mine was ordered on Feb 11th and now will be delivered on Monday the 17th. Waiting is not easy :mad: It was originally supposed to be here today.

So do you have a playlist ready?

Many. :smile_phones: Patience, not so much. Choices, only one, wait.

The people who documented the burn-in on the Bifrost, actually did not listen to it during the burn-in, in order to remove "brain burn-in" as a possibility:

Since Schiit agrees that the Teflon capacitors need to be burned in (and they do so with their prototypes), why is it the subject of ridicule ?   Simple chemical change due to application of heat.

What property of the capacitor changes with burn in?

Oh man, you think my response was ridicule.  It really wasn't.  My degree is in psychology, and I tend to think in those terms, not engineering terms.  I have a healthy respect for the many areas of the brain involved in the processing of music and sound.

 

At the same time, I don't find that electrical burn-in and brain burn-in are mutually exclusive, either-or, binary concepts.  It is most likely a continuum.

Then you are familiar with the term "FPP" manifesting in a dissociation of capacitance. It is related to transistors having a bipolar disorder related to a musical composition known as a fugue. Bach was known for his fugues. :wink_face:

A few days in to uber land and I'm very impressed by the improvement in clarity, which seems to my ears more significant on my Sig Pros than on the LCD-2s. 

 

I reread the early bit of the thread as, like many, I've not aligned the LEDs well. I'll try again when I fit the USB card...
