Reading reviews for headphones amplified make me feel like my brain is slowly liquified. What's the point of these tubes there? I can bet that the tubes aren't even soldered into anything and are there just for swag. The reviews are also as retarded as it can possibly come:

"I left the amp to warm up for 6 hours with my hardware white noise generator and it still produces suboptimal sound."

WHY ARE AUDIOPHILES SO GODDAMN FUCKING RETARDED? Is this how computer people sound too to the uninitiated? What the ever living fuck?

There's educated audiophiles, and then there's placebo peddlers.

What you encountered is the latter.
The former will tell you that things like tubes are bs. Anything over CD quality is imperceptible. You don't need special cables to carry digital signals etc.

If you think you can hear above 22khz, good luck with that delusion.

@alyx hahaha no, I don't think that. I'm lucky if I can still hear even 18kHz. But that's beside the point.

The idea behind using highres audio is that lowpass filters eat shit, and if you record live instruments at 44kHz, it's possible that some harmonics will wrap into lower frequencies and add noise. It's just easier record stuff in the highest possible sampling frequency and filter out that shit in digital.

@alyx although, switching from 16bit sample size to 24bits definitely adds resolution and this can even be audible in some cases. These days there's literally no reason not to use 44kHz/24bit encoding for storing music.

@newt
>24bits definitely adds resolution
Yes, but it's not actually needed. To properly make full use of that added resolution, you'd need to blast music loud enough to incur hearing damage.

@newt
More than 44.1kHz 16bit makes sense for mastering archiving, but not for end user.

@newt
>The idea behind using highres audio is that lowpass filters eat shit, and if you record live instruments at 44kHz
Either you misspoke, or you don't understand how recording digital audio works.

The 44.1kHz of the CD is NOT your audio frequency. It's the sample rate. With that sample rate you're reproducing sounds at as high as 22.05kHz. And there's really not much going up there with even classic music instruments. You're not recording live instruments at 44kHz, cause they just don't produce sound that high (and not even at 22.05kHz). It's why lossy encoders like mp3 cut off with lowpass filters even lower, at 16-18 kHz.
Sure, in theory you get those artifacts, but in practice you don't actually hear them, unless you did something REALLY WRONG during mastering.

@alyx @newt
>You don't need special cables to carry digital signals
sure you do
sometimes it's gotta be optical to help silence an obnoxious ground loop between your PC and receiver, and you've gotta buy those stupid plastic optical fiber toslink cables instead of using NORMAL fiber that you already have plenty of.
@skylar @alyx @newt
okay, now tell me more about your field recordings
@neo @alyx @newt sorry chief i don't have a field
but the audio goobers could have just standardized multimode fiber with an SC connector instead of special ones :(

@skylar @newt
I repeat: you don't need special cables to carry DIGITAL signals.

What does a crappy digital audio cable actually sound like?

@alyx @newt if it's copper, it can carry ground loop noise
maybe my receiver is simply a piece of shit, but going with optical fixed it

@skylar @newt
Maybe your cable is broken, cause you'd need A LOT of noise to fuck up digital signal. And you either get sound or you don't. There's not much of an in-between where you get audible noise over your audio.

@alyx @newt it was somehow being carried over into the analog side....but it also did the noise when i attached a ground wire to the receiver's ground lug.
the cause is probably the outlet it's plugged into being served by an UPS rather than nice smooth sine wave mains power

@skylar @newt
>UPS
... you know what... I'm not even gonna ask...

>the cause is probably...
Have you considered actually testing this hypothesis?

@alyx @newt it's YOUR fault i got out a spare receiver to test with

root cause was the other one being shitty or fucked up internally in a way that it didn't like UPS power.

and sure it's not ~normal~ to have an enterprise UPS in the basement and feed a subpanel from it that serves several computer equipment outlets around the house, but it's how i do things!

@skylar @newt
Having UPS for computer stuff is perfectly fine and recommended.

Having UPS for your hifi stuff is a waste imo. If I have a black-out, the last thing I'm concerned about is being able to play music. But I've already said too much. I'll leave this topic.

P.S. Not the first time I've heard about things not liking UPS power. Some people will blame the UPS quality when this happens.

@alyx @newt does it NEED to be on there? hell no
do i like not having to push the power button on stuff after the generator kicks on during an outage? yes!
