    So, what you say is that if you use a perfect DAC and a perfect amplifier the result of playback will be the best you can get regardless of PC hardware.
    Absolutely not! What I say is that every PC generates electric noise patterns and EMI patterns, and that, when it comes to audible differences and the impact of these differences on the musical experience, which are by definition subjective, the characteristics of these patterns [the characteristics of which tend to correlate with hardware activities/processes of the PC in various complex ways, and that aren't necessarily always very subtle...] are among factors that can affect DAC performance, BUT... if these patterns are adequately blocked from entering the DAC, then these audible differences become effectively suppressed to the point of inaudibility─as that's the meaning of the word "adequately" here. So, if they already are blocked by the DAC to such an extent that they have no audible impact on DAC performance anyway in the first place, then, for reasons that should be completely obvious, there's no point trying to tweak them in any way whatsoever. This doesn't also imply that my DAC and amplifier are perfect. Just that they are close enough to perfection to not experience any such troubles. Not experiencing any troubles can be very relaxing. I think people should try it!
    I have to agree about DAC & amplifier and their power supply but I have to disagree about PC hardware and the way OS manages it.
    Like I already said in my previous post. Been there, done that.
    wtfplay-live is a minimalist player made on Linux by a high fidelity lover, uses command line only, in a DOS like environment, needing a USB stick or SD card or hard drive to boot from it and then plays your .flac and .wav files from RAM. Its size, OS and player together, is about 25MB.
    See above. Been there, done that.
    If you don't know it, you can find it here: wtfplay-project.org
    It's a 'primitive' player, seems to be painful but is not and finally really worth.

    It 'magically' takes the audio experience to the next level! And of course, there is no magic. Native (not by simply shutting down unnecessary background processes) minimal use of PC sources means truly much less noise, resulting an output with better, clear and neutral sound.
    Τhe better the source (PC output), the better sound you get. Then, high quality cables and perfectly power supplied DAC, Amp and speakers take over the rest.

    Perhaps, that player will change your mind...
    Perhaps, getting a better DAC will change your mind. Because, I already tried that player, and, the only times when it improved the sound were... you guessed it: after I switched my DAC to one of the inadequately isolated ones that makes them susceptible to this. Now, of course a DAC that isn't susceptible to this isn't necessarily always going to be better sounding. It greatly depends on personal preferences and on whether you like the kind of sound that is extremely revealing and neutral. One of the major downsides is that every small imperfection in the recording is revealed so these imperfections become distracting, which tends to become fatiguing, but anyway, I can always throw a blanket over my speakers whenever I need to...

    Hi there
    the old Computer expression GIGO (Garbage in Garbage out) applies to Audio too. If the source is rubbish no amount of expensive DAC's , old fashioned expensive linear vacuum tube class "A" amplifiers and horrendously expensive quality speakers will improve it.

    Typical computers don't have sensible sound cards - they are built usually more for gaming sounds and movies -- totally different requirement to serious music enjoyment.

    Some mobile phones have passable DAC's in them these days so playing music from a phone into a decent amp is OK --but for quality "Hi-FI" sound don't even THINK of using blu tooth !!!!. Blu tooth is OK for wireless headphones and TV sound bars etc but for mega high quality serious music --forget it.

    OK! I'm going to throw my Benchmark DAC3 HGC out of window and you may keep going with...blankets.

    I have compared the Benchmark DAC3 HGC to what I have. The Benchmark sounded noticeably less detailed and very harsh to my ears. The XMOS chip in the Benchmark is soldered to the main PCB, i.e., the exact opposite of what really is needed to eliminate susceptibility of the sensitive analog components to electric noise like how I already have described (twice).

    Of course I don't really put blankets over my speakers.

    You may send an e-mail to Benchmark to enlighten them...

    Hi,
    I always use audacity to edit and output to wav
    Doubt it improves audio quality though just makes me happy I got rid of the stupid 5+ seconds of dead air on front and ending of songs lol

    I'm surprised no one has mentioned the place that flogs £1,000 cables. These must improve the audio quality ?

    A company that can sell a DAC in that price category should already know much better so I'm not going to waste time trying to talk to them. Their DAC3 HGC not only sounds muffled and very harsh, but also it sounds too bright to my ears (I'm using an Emotiva XPA-2 Gen1 amplifier, which is neutral like Switzerla.. oh, ehh.. well actually nevermind. )

    "muffled and bright" Are you sure about meanings?
    I like theory but I think, in some cases, confuses...

    If you really want clear and neutral sound, trust your ears, not your feeling.

    And really, I don't want to speak about psychoacoustics and also, why many studios in the world prefer Benchmark.

    Is that because singapore still uses 25 Volts for the electricity supply generated by a man on a bicycle in front of the property so no danger !!!.

    The fuse might be in the plug itself (as per the 3 pin UK type plugs) or in a fuse box / switch isolator.

    -- in Europe it's 220V - and I wouldn't mess with it -if something is rated to blow at 3 amps say then if it blows you can be sure that there's a failure somewhere. A dead short for example will make a thick piece of copper wire get red hot very quickly !!!!!!!!.

    I agree decent "Old time" Amps and Studio reference quality speakers really do sound so much better - however so many people have got used to tiny bud earphones playing essentially thump thump nightclub type music or movies with mainly sound effects rather than any spoken dialog so I think you are essentially preaching to deaf ears on that one.

    There's no reason though why ripped CD's or other digitally produced music at decent levels of compression shouldn't sound OK as well even on decent pieces of kit. A properly recorded mp3 at 320 kbs is usually perfectly acceptable specially is using SENSIBLE headphones !! and decent levels of M4A music also OK too as per some Internet classical music stations such as BBC R3.

    Compressed mp3 music less than 256 kbs really sounds poor through high quality speakers, 128 kbs sounds quite hideous and 64kbs is even almost unlistenable for Audi books etc. Don't even try for music at 64 kbs.

    Cheers

    You're humorous. and you worry too much, how would my computer fuse less power cord rated at 250v 10a grow hot when not overloaded ? I always use online youtune to mp3 convertor and to 320kbs, does sound much better.

    For cables 10% of your sound equipments is sufficient. I won't pay a $1000 or even a $1 for power plug with fuse unless free but i wil need to mofified it. I use power cable without fuse which i brought from my country for my computer.

    Conversion from mp3 to wav format sound less compress and decent quality with good source with my setup. Of course it will never sound like a CD. BTW, games on disc or digital download purchase also come in compress format and un compress when
    installing, any difference ?
