    Audio Myth Buster Thread

    Sign in to disable this ad
    I just found out that tubes do not add warmth to your sound. In all my years both playing music and doing HR I had never heard this before and I feel like I have just saved myself a nice little bundle of cash as I was saving for some tube comps and a mic. Just coz they had tubes thinking they would add some of that warm mojo. Not ture!! BUSTED.

    I'm thinking what other myths are out their, so please if you know any audio myth post them here.

    Hi, if this is true it wouldn't surprise me, because far too much bullshit and snake oil is attached to the subject of vacuum tubes. However, I'm very interested as to what brought you to this conclusion, where you are drawing your evidence from, data etc.

    I actually think that saying tubes DO NOT add warmth, is just adding to the myth pile...because it's such a broad, generic statement.

    As noted in the other thread...it depends on the complete circuit, and some tube gear does add what is usually referred to as "warmth" (which is kind of a silly term to begin with)...and that is about saturation, distortion, etc.

    As also noted in the other thread, all tube gear does NOT "only/always add harmonic brightness"...as the YT guy was saying...which is also yet another myth HE is spreading.

    True...*tubes* alone in an otherwise neutral circuit may not add shit....but in most tube circuits there is more to it than just that, and YT videos where some guy posts his personal opinion as global fact and science...only spreads a different kind of myth.

    That guy wasn't even looking for warmth...he was looking for punch...and his video is circular and doesn't prove or disprove anything, IMHO. So because he misunderstood what gear to use for what he wanted...he turns it into some "myth busting" thing...when it's more about his own misconceptions being realized.

    (PS...get the VLAs..you will like them).

    At some point...people need to stop reading and watching YT, etc....and instead, they should just start experiencing and finding out what works for them, and what preferences they have for audio...instead of buying into what someone else prefers. This shit is all so subjective, that you really need to experience and form your own opinions....and then go with that.

    Good design and implementation is what brings 'warmth' to a piece of gear. It can be tube gear or solid state. Of course it's cheaper to make good 'warm' sounding solid state gear than tube gear. Almost anything with a tube in it for less than $800/channel is just a marketing ploy.

    Here is a video the busts the myth about digital audio being 'stair stepped'. This should really be a sticky.

    He kinda played on the more simplistic misconceptions that digital audio makes the final analog sound have stair-steps...which is NOT true....but the underlying reality is that what he gets at the analog output is just a *reconstruction* of the original analog signal, and he says that, though he chooses not to dwell on it.

    Well, that's because it goes without saying. If an analog signal is converted to digital, when you convert it back, it has to be a reconstruction. I'm not sure I get your point.

    There's that whole myth about "impedance matching" that confuses people all the time. The truth is that in all cases this side of the power amplifer>speaker connection, we always want to mis-match impedance from a low source to high(er) load, and the greater the mismatch the better. Well, that assumes that we actually want to pass as much signal as possible across as big a frequency range as possible. If you want everything you can get, you want at least 10:1 ratio of In-Z to Out-Z. You can plug a microphone into a line input. You can plug a line output into a guitar amp, pedal or "instrument" input. There may be level issues, or other problems with the connection, but it will never be the impedance that causes it.

    4:15 - 4:35

    He basically shows that it IS stair-stepped while in the digital domain...and then it has to be reconstructed and converted to a non-stair-stepped signal in the analog domain.

    So his whole argument is that when converted back to analog, it's not stair-stepped...which I guess some people use to think it was for some reason...yet he's basically trying to imply that it's the same analog wave that went in...which is BS...it's not, it's a reconstructed/fabricated wave from the digital depiction of what the audio was and what it should be when it's analog again.

    Don't get me wrong, I'm not looking to argue some analog VS digital point and/or which sounds better...just saying that he's presentation somewhat glosses over certain points so that he can show the output in analog is not stair-stepped and the same analog wave that went in. It's like he's saying nothing happens to the original analog wave...which is not an accurate explanation.

    Oh...and you made me go back and watch it again so I could find the point on the timeline. I find the guy generally annoying to listen to and to watch...which has nothing to do with the actual audio stuff.

    Yeah, John @ Massive has been saying that for years. Tubes are not the source of 'warmth', it's the transformers. I don't know myself, but I'll take his word for it.
