The interesting thing here is that, whilst the blind ABX test is quite convincing as to the effectiveness of hi-bit rate compressed audio I am more 'comfortable' listening to lossless.
This is exactly the same effect that I get when listening to a wired as opposed to a wireless system. I know the results should be, 'effectively' the same but to me, they are not, quite.
In some respects I am a fairly uncritical listener, mostly I have no problem listening to the music and ignoring the hi-fi, but when I do think about it, the feelings expressed above remain.
I am reasonably convinced that these are pyscological/psychoacoustic issues, but they are damn difficult to shake. I know I am susceptible to such effects (I think most people are) but they are difficult to test.
My own experiences about the effects of speaker cable of unequal lengths have been tested and I understand that I only hear a difference when I know the cable lengths are different, if I do not know, there is no problem. However even having proved that I can not tell the difference, to this day I still have to use speaker cables exactly the same length.....!
A very good post.
It doesn't proof anything but shows that this (and other) hobbies can be more than 'just' science, as important as that may be.
This is true. Where it becomes contentious is when recommendations that cost people money that are also irrelevant in practice - That is why me and all the other "objectivists" get on the cable, HD, supports etc bandwagons.
HD is pointless. I have done at least half a dozen tests now and it is pretty obvious that HD adds nothing in terms of human-audible sound quality.
Lossy vs Lossless - Much more difficult to scientifically test, as the "null test" cannot work here. ABX is the only way. However I am convinced a well-ripped CD at 320 Kbps is indistinguishable from lossless. I have tested a few people on what I consider a revealing setup and nobody can tell them apart. I have seen one published pass on 320 Kbps MP3, but with little to back it up other than the person's word...However it does leave a splinter of a possibility that someone trained to hear the difference may just about be able to? Saying that, it has zero effect on soundstage, separation, bass, treble, sibilance etc. And honestly I am now convinced enough to have MP3 or AAC as my main source.
Analogue cables - IMO make no difference that is audible providing they meet at least minimum specs and providing they haven't some crazy electrical properties. The idea that a silver lining makes any difference is laughable.
Digital cables - Zero difference providing they work
Supports - Useful for a record deck. That's it.
Blue ray players playing back blue ray through HDMI - Pretty much identical from the cheapest £40 deck to the crazy priced exotica. The only possible differences can be extra processing or the way they handle the compressed data.
Transports - Zero difference unless the manufacturer has messed something up.
DACs - Certainly differences, but not worth a damn once you have a well implemented example.
Jitter - Irrelevant
