I see the issue with ABX blind testing


I’ve followed many of the cable discussions over the years with interest. I’ve never tested cables & compared the sound other than when I bought an LFD amp & the vendor said that it was best paired with the LFD power cord. That was $450 US and he offered to ship it to me to try & if I didn’t notice a difference I could send it back. I got it, tried it & sent it back. To me there was no difference at all.

Fast forward to today & I have a new system & the issue of cables arises again. I have Mogami cables made by Take Five Audio in Canada. The speaker wire are Mogami 3104, XLRs are Mogami 2549 & the power cords are Powerline 10 with Furutech connectors. All cables are quite well made and I’ve been using them for about 5 years. The vendor that sold me the new equipment insisted that I needed "better" cables and sent along some Transparent Super speaker & XLR cables to try. If I like them I can pay for them.

In every discussion about cables the question is always asked, why don’t you do an ABX blind test? So I was figuring out how I’d do that. I know the reason few do it. It’s not easy to accomplish. I have no problem having a friend come over & swap cables without telling me what he’s done, whether he swapped any at all etc. But from what I can see the benefit, if there is one, will be most noticeable system wide. In other words, just switching one power cable the way I did before won’t be sufficient for you to tell a difference... again, assuming there is one. So I need my friend to swap power cables for my amp/preamp & streamer, XLR cables from my streamer to my preamp, preamp to amp & speakers cables. That takes a good 5-10 minutes. There is no way my brain is retaining what I previously heard and then comparing it to what I currently hear.

The alternative is to connect all of the new cables, listen for a week or so & then switch back & see if you feel you’re missing anything. But then your brain takes over & your biases will have as much impact as any potential change in sound quality.

So I’m stumped as to how to proceed.

@tonywinga I have no anxiety at all. In fact, I have none.

I was just saying much of what audiophiles actually hear is this bias. I care less what people spend their money on. 

Are you sure?  Perhaps an ABX test is in order.

Bias is what it is all about.  Some people like the sound of speaker A and some speaker B.  They both sound the same to my wife.  She is all about looks.  Looks factor into the bias even if the lights do not need to be on to listen.  If the Nissan Cube were the only car available for sale I might just walk to the store.  

Just saw a video about the BIC ball point pen.  It revolutionized writing.  The video claims the BIC pen is responsible for increasing the world literacy rate from around 30% in 1950 when it became available to over 85% a couple of decades later.  Over 120 billion BIC pens have been sold, they said.  With such an appliance so sure and capable, why is any other style of ball point pen needed?

I was just saying much of what audiophiles actually hear is this bias.

@botrytis  And much of it is not.  So what?  Do you eat blindfolded?  In the end we buy what we like most all things considered, so who cares?  While biases may be at play to some extent (and probably varies greatly by person BTW) they don’t necessarily undermine or overwhelm what we hear and do not invalidate the purchasing decision process.  Saying people are biased seems pointless much like in the way those who say there are no differences between cables because they’re not proven with measurements, and both are useless and tiresome IMHO.

@soix I have eaten blindfolded before. My wife took me once to a restaurant that specialized in blindfolded dining. It was to say an eye-opening experience. I didn't appreciate it at the time, but on reflection should have appreciated the lesson taught there.

I have a friend in France, who knows a blind audiophile and HIS take on musicality and equipment is interesting to hear. People should be open to the idea of blind testing. It doesn't take away anything, but it might save people money and the charlatans in the audio field, wouldn't survive (and there are plenty of them out there).

The point being, sighted listening, IS BIASED listening. Say what you will, there is a reason it is the gold standard for testing w/o biases.

We can agree to disagree, but my point is valid and based on science.

botrytis: Don’t fear it, embrace it. We learn through failures and mistakes. If you get taken- lesson learned. But to miss opportunities because you fear it could be a ruse is a real shame. Audio is to be enjoyed- it’s all about the music. Either you like the sound of something or you don’t. It’s just like a song- you either like it or you don’t. And even then a song I didn’t like before I like now and sometimes a song I liked before I no longer like now. The same thing might happen with your stereo. You like how it sounds today but one day in the future you might want a different sound. That doesn’t mean you failed to do proper ABX testing. It means tastes change.

I can’t imagine how you can enjoy anything if you have to analyze and ABX test everything. I’d hate to go grocery shopping with you.

As for eating in a restaurant blindfolded- kudos for your bravery.  I wouldn‘t do it.  Strangers feeding me food I can‘t see?  No way.  I‘ve been in some countries where I would definitely not want to do that.
