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.

I moved the sub to the right, between the stand and the right speaker, about an inch behind the front of the speaker. I've also ordered a second sub.

As for the cables, I'm satisfied with my assessment. I don't believe anything I do will result in a dramatic difference and for the price it would have to be dramatic. So I've sent them back. I had neighbors interested in hearing the difference but my opinion of the sound is all that matters to me as I'm paying for it.

Neighbor blind test is the ultimate one of them all. You get the true ABX blind test using non audiophiles who are not familiar with your system. There ain’t no chance in this world that there would be any difference identified between cables.
You would be promoted to a rank of a General by the minions at ASR. You should have totally done it. 

My very rational and very intelligent half deaf wife is ASR first supporter ...😊

We stay married but we differ here ...😁😊😉

I had no neighbor nor any need for one ... 😎

( my story is a parable here)

 

 

Audphile1:  I wanted to disagree with you but then I thought of my wife and brothers.  You are probably right.  The differences seem obvious to me.  And my two sons.

Seems like any non audiophile that hears my system expects to be blown back into their chair by the bass.  That‘s what seems to matter.  They are generally disappointed.  I might as well just set up the Sony boombox behind my speakers that my brother talked me into buying.  I‘m sure my wife wouldn‘t know the difference.

Tony lol. Exactly. 
One of my friends after listening to my system asked why I needed two subwoofers, pointing at Pass Labs X260.8 mono blocks. 
Neighbors are just as qualified.
