... In article , 123456789 'warmth' is distortion, which can be added if that's what a person wants. nope. tube amps add distortion whether or not the person wants it. some people might want it, which is why they buy tube amps. others prefer more accurate sound. the distortion a tube amp adds can be added to solid state amps but it can't be removed from a tube amp. what can't be done is removing distortion that's already there. My local big box and book stores are selling LP vinyl records. Some permanently distorted people still out there... they aren't selling very many and certainly not because of their audio quality. cds can be limited to mimic vinyl. Why would anyone want to make a CD mimic vinyl? because some people think vinyl sounds better. you can always downgrade sound quality, but you can't add back what isn't there. I can see a market for recordings, especially of older albums that were originally issued on LP, with the warmth of an LP played through a valve amplifier. Whether that is done by having a separate recording, or whether it's done by modified limiter and frequency response settings to make a CD through a transistor amp sound like an LP through a valve amp, is neither here nor there. When CDs and players first came out in the early 80s, salesmen were very definitely pushing CDs as being superior. I can remember a group of us from university went to a hi fi shop (similar to Richer Sounds, but almost certainly not RS) and the salesman went through his spiel and his demonstration. We were blown away by the sound which was dramatically better in dynamic range, lack of distortion and especially lack of background noise. The salesman had the same album in both formats, played through the same amp and speakers, which was a good side-by-side test. When he got onto scratch-resistance, the fun started. The salesman pulled out an old CD (not in a case) from his jacket pocket in which there were pens and keys. He got a sewing needle and scored a deep groove in the CD. It played flawlessly. My mate, a great big burly bloke, said "Giz that CD and needle" and he carved a trench in the disc. It played almost flawlessly, with occasional glitches. "*Now* I'm really impressed," my mate said. "Do that to an LP and you'd rip the F-ing needle off". |

I buy USED LPs and CDs at my local Goodwill store for a buck or two each and rip them to MP3s. They sound great on my phone using my analog earbuds. Good thing it has an analog jack... |

I'm glad that you NOW agree that flatness IS an issue in audio design. one of many, and actually not that important because speakers aren't flat, plus room acoustics will have a much bigger effect on flatness than any amp ever will. what matters more are the various forms of distortion. From YOUR link (emphasis mine): it was *your* link. i just pointed you to the distortion part. I'm glad that you NOW agree that it is possible to have tube amplifiers with the characteristic wide bandwidth and sound of modern transistor amplifiers. nope. you have that backwards. modern transistor amps can sound like a tube amp by adding the distortion a tube amp adds, but it's not possible to remove the distortion from a tube amp to sound like a modern transistor amp. |

You have used that argument several times, applied to different aspects of audio. I bet you can't cite an example relating to DACs on high level equipment. numerous times, because it's true. people *think* they can hear a difference, but when put to the test, they can't. they do no better than chance. The example you originally quoted was in a different context altogether. nope It was. CD vs vinyl. Nothing to do with DAC A vs DAC B. it doesn't matter what it is. an objective-double blind test will show whether there's a difference or not. Quite agreed, but that was not what we discussing. In almost the last of the text which you snipped before the current post, you said "not that there is an audible difference, except perhaps the $5 one ...". This led on to you writing: "some might *think* they can hear a difference, but they can't. objective double-blind tests consistently show that people do no better than chance. in other words, they're guessing." In other words you were arguing that double-blind tests showed that double blind tests had shown that people could not tell the difference between one DAC and another (except perhaps for the $5 one). But you have never cited double-blind tests of DACs. it also applies to more than just audio. there was a double-blind test with wine, where expert wine tasters couldn't identify the cheap wines from the expensive ones, including when one of the 'red wines' was white wine + food colouring. If we accept your argument then double-blind tests are a waste of time under any circumstances we are discussing with you. nonsense. objective double-blind tests are never a waste of time, except for those who have something to hide. Then what is the point of your reference to wine? that people *think* they can tell a difference for all sorts of things, but when put to the test, the fail, big time. it doesn't matter whether it's wine, audio, cameras, and more. You don't need a double-blind test to determine whether people can tell whether or not a light is on in a room. In most cases the possession of the necessary discrimination is blatantly obvious. if one product really is better than another product, an objective double-bind test will show it. it's exactly what someone pushing a 'better product' would want. In fact, and for example, practically nobody could fail to detect the difference between my PC speakers and the Arcam DAC feeding the Quad amplifier and Z4 speakers with their ribbon tweeters. some will and some won't. others won't care. so what? The difference between the two DACs is not as great but it is quite audible. then something is wrong with at least one of them. ADC is easy. But DACs are hard. Just ask the experts. the experts will say both are easy or hard, depending on numerous factors. Fudge. -- Regards, Eric Stevens |

Recall of audio is as flawed as recall of any other memory. We don't replay a memory, we reconstruct it. That reconstruction depends in large part on the emotional ambience (eg, social setting) of the original experience. Example: I don't think you'd want the recording to present what the concert actually sounded like to you in when you were stuck in the middle of the crowd.... yep. |

It was just a bit of attempted levity. Guess I needed a smiley. The ringing in your ears may be generated in the ears or the brain or both. I don't notice the ringing unless I think about it (same with the floaters). Love those brain filters. I have a number of recordings with crowd noise and I don't find them objectionable. That's not what I meant. Those recordings combine multiple tracks and are carefully massaged so that the crowd noise does not interfere with the music. Perhaps. But my live recordings sound pretty much like the concerts I remember. I've been at concerts where I could hardly hear the music itself. And others where the music drowned out the crowd noise. My GUESS is that we may like different kinds of music as the concerts I remember and currently attend are a bit more refined than what you describe. But that's OK cause music is a subjective thing... |
