Real audio tip: if you have a constant hum when hooking up one outlet-powered device to another, it's because the two devices have slightly different ground voltages and you need one of these

I think it's just a high pass filter

My best buy had one on hand but i had to ask a clerk to poke around the back

This won't happen if one of the devices is battery powered, so if it happens with your desktop->TV but not laptop->TV, that's the problem you're having

I like that audiophiles are all about analog equipment now

"Now that digital amplifiers that amplify the sound perfectly, with no distortion, are widely available to the general public, we need something to stand out and be elitist about. Let's intentionally use analog equipment that introduces distortions and make up some bullshit about a warmer sound"

All audio amplifiers are analog because speakers are analog. Newer stuff will often be digital at the inputs, but must be converted to analog before the final amplification. And older equipment often had better final amplification components than newer stuff, at least until you get to really expensive equipment.

That said, most of the audiophile wankery about vintage gear is pretty dumb, you'd often be better off buying better speakers than going nuts trying to re-cap and restore a old receiver that you paid a shitload of money for from some collector. However, if you can get one cheap, it can be a fun project.

Like, LOL, your $100 MP3 player has really lovely firmware. Get over it.

Was it the FiiO X1? I'm thinking about getting drunk tonight and buying it because I got used to my ipod classic with the wheel and just want a decent mp3 player that's not a smart device.

If you're experiencing hum just cut the power cable and hold both leads. You become the ultimate noise filter that's in tune with your ears

Yeah, I agree, the only real advantage to tubes is they clip gracefully, so at balls-out volume, they tend to sound better to our ears. For normal listening there's no need.

I think it's just a high pass filter
The noise sometimes presents as high pitched squealing (because of poorly designed switchmode power supplies), that isolator still works in those cases because it's not a high pass filter - it's basically a 1:1 transformer, and the isolation that transformers offer means that the devices can't ground themselves to each other through the signal cabling.

You can also solve the problem by tying everything's grounds together properly, and I prefer doing this because those isolators introduce their own (real) distortions.

Ground issues can present in other ways too - back in the days of tube TVs I had one that would display faint scrolling diagonal lines unless I used the thickest s-video cable I had (it came with my radeon 9800pro and must've had a real beefy ground shield). Eventually I had enough of it so I connected everything's grounds together with the kind of wire used for power cable (which is a lot thicker than what you'll find in an rca lead) and that fixed the problem.

Not sure if serious? I think I might have actually tried this, and my TV doesn't have a ground prong.

Yeah I know that you can wire your house properly to avoid this, but that's not an option. Plus I had it with a TV that doesn't have a ground prong so I don't really understand how the circuitry works.

You know what I hate the most about audiophiles? They never say they like music, they say they like "audio." As if for them it's more about loving around with the sound quality than the actual music itself.

Whenever an audiophile posts a pic of their setups, you almost always see the vinyl on their shelves is 90% Tuning/Demo/Benchmark records, with a few "safe" albums thrown in. Audiophiles are even more afraid of being called out on having bad music tastes than they are of being called out on cheap equipment. That's why you only see the same "safe" albums over and over again in every audiophile setup pic. (Beatles, Pink Floyd, Rolling Stones, and a few others that they feel are incapable of being criticized)

Most of them don't actually to listen to music, they listen to their equipment.

I don't know about that one, most of the audio sups and engineers I know love to buy nice schoeps, dpa, etc... mics. They definitely carry a hefty pricetag.
