![]() This is bit perfect audio.Īlthough volume changes technically break bit perfect data, the algorithms that change the volume in the digital domain are done with much more precision that the actual data, so volume adjusted data is usually considered to be bit perfect. So, methods were developed to bypass the mixer and send the exact bits that were in the file to the digital output. The user or the player had little or no control over these changes. It was not just volume, but the data would also get re-sampled to other sample rates. The idea of bit perfect audio came about in the early days of computer audio when people realized that the Windows "mixer" was making unknow changes to the data. I mean, does it audibly matter in terms of sound quality that the eq is off and the volume is fixed at 100%? A part from how loud it will sound, of course. ![]() ![]() ![]() Just trying to find out if I should at all worry about getting a bit perfect output from my WiiM Pro Plus to my Denon receiver, connected via line out. I know that the best way is to test for myself, but what are your thoughts? Should I aim to make the connection to my receiver “bit perfect” and just turn down the volume on the receiver accordingly (if we assume that I will not be using the Wiim’s eq) or does that really not make an audible difference to non-audiophiles like me, who just want the best result within reason. I might also want to play with the eq, but I am not certain that I will use it. I am inclined to fix the volume at 75% to match the level of my turntable, so I have a similar volume level between sources on my receiver- and don’t get a chock if I forget to turn down the volume after switching from turntable to line in. I mean, does it audibly matter in terms of sound quality that the eq is off and the volume is fixed at 100%? Apart from how loud it will sound, of course. If anything, I said the opposite and I enjoy demonstrating that as far as cables are concerned, there is a lot of psychoacoustics.Just trying to find out if I should at all worry about getting a bit perfect output from my WiiM Pro Plus to my Denon receiver, connected via line out. After the Test response, I have the Test check which cable is connected and write down the result. I have the 2 cables listened to without bandaging 2 times and I have the Test choose the listening position which remains blindfolded for the time in which the cables are changed and during listening. the owner of the cable withdrew from rehearsals in the following days. The last test performed last week, 1 meter USB printer cable purchased on amazon and 1.0 m Acoustic Revive R-AU1-PL USB cable from 200€. In the following days, on average, the results worsen. I can say that out of dozens of tests it is difficult for each test to reach 6-7 useful results. I grant 8 useful results out of 10, even if it would be legitimate to expect 10 out of 10. I repeat the test on 2 more days of the same week (it would be the same within the month or year). I do 3 tests in the same day, about 1 hour apart. My methodology is nothing special and is based on common sense and repeatability. There are in fact at least 2 aspects much overlooked by esoteric cable enthusiasts regarding the intrinsic quality of a cableġ) Mechanical and abrasion resistance, mainly due to the very high number of cycles to which enthusiasts of this discipline subject cables and above all hi-fi electronic terminals.Ģ) Constancy of performance over time due to the degradation of materials and from this point of view silver is very bad! Click to expand.Given that practically all the cables I use I build them, but for a very different reason from the search for sensational performance.
