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?

:akko_wtf:

@newt
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.

@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 @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

>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!
