Kevin Haskins;493694 Wrote: THD+N is pretty useless as a sole metric, that is true. Especially with loudspeakers where the on/off-axis FR measurements are more important. But... when you are splitting hairs over 0.005 THD+N Vs. 0.0001 THD+N, it is almost guaranteed that there is little audible difference between the two. Also, you have to more broadly define how it is measured. Small amounts of odd-order are very audible, higher amounts of even order harmonics much less so.Also, you would have to know where the distortion components are in relation to the frequency band. You can listen to 10% THD at 20 Hz and not tell a distorted sinewave from an undistorted one.So... yes, it is more complicated than a simple single number but there is plenty of research showing what is and what is not audible. With transducers, we are very happy to get 1% THD+N at higher listening levels. Those distortion products are both even odd order depending upon the mechanism causing them.I'd say we are pretty safe in saying that those non-linearities swamp those that are another 40-60dB further down. It is like saying you can appriciate the sound of your hifi while using your chainsaw. Nobody would consider that a rational exercise, yet we routinely make such comparisons when judging audio components. The rational person, turns off the chainsaw before they fine tune their audio system for best performance. The irrational person quibbles about the nuances of the performance while ignoring the chainsaw. The distortion of 0.0001 in the mountain can generate a much larger distortion because in our downstream facilities are amplifiers that amplify everything that goes into even the input distortion ... The DAC is selected if you want to increase the detail or to gain a better scene to your own tastes. You say that beyond a certain threshold rather low, (the DAC of the Touch is pretty cheap) do not feel more different. This is not true. Want to support that most audiophiles are deaf? There is an explanation to this. The human ear is an instrument that has had thousands of years of evulozione. What we feel is interpreted by the brain. This explains why there is a DAC with the same distortion feel differently from other DAC. Our ear is perfettamnte able to distinguish small changes that occur in a very short time, while great changes continue over time are not assimilated in the same way. is why we feel the differences between a cable and the other in the presence of a chainsaw as you :-)) I know that we are slightly off-topic:-D -- perito industriale perito industriale's Profile: http://forums.slimdevices.com/member.php?userid=34754 View this thread: http://forums.slimdevices.com/showthread.php?t=72246 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Kevin Haskins;493573 Wrote: Sure.. I'm just pointing out that if you cannot hear a difference, then it doesn't matter.You don't get brownie points for making something less inaudible. I think the Touch used as a server and outputting via SPDIF directly into a DSP or a DAC is the cat's meow.I see no reason why you need to spend more for that task. well, depends that which are the quality of the speakers utilized, the environment and which is the ability to hear differences. :-)) For most people is enough quality mp3 that does not mean it's the best, the difference between an mp3 and a wav file I think it's recognizable by equipment of average quality. Certainly if there is some component that prevents the plant to hear these differences is pointless to change the DAC I will experiment with the internal DAC of the Touch but I think i will use the coax output to connect an external DAC like the Musical Fidelity VDAC that promises good performance at relatively low cost -- perito industriale perito industriale's Profile: http://forums.slimdevices.com/member.php?userid=34754 View this thread: http://forums.slimdevices.com/showthread.php?t=72246 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

You can not compare the distortion of the signal and the power .. :-O Distortion then is not the only parameter on which you decide the quality of a component hifi / hiend! is important but not the only, if you're a designer you should know -- perito industriale perito industriale's Profile: http://forums.slimdevices.com/member.php?userid=34754 View this thread: http://forums.slimdevices.com/showthread.php?t=72246 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Hello, i turn to the technicians and designers of the apparatus, serebbe very nice if we could clarify some of my questions because I think the subject very interesting. Any answers will be posted on other forums as Italians were no reports of common interest, there is great excitement around music liquid! I'd like to understand the quality of the program used as a player and, above all, on what software rev ... compete as a player is quality compared to PC player like Foobar 2000 + driver on Vista or WASAPI Seven, or an iTunes on MAC? What kind of HardDisck support and what capacity? They also support all USB HD 1TB? -- perito industriale perito industriale's Profile: http://forums.slimdevices.com/member.php?userid=34754 View this thread: http://forums.slimdevices.com/showthread.php?t=72246 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
