A-B testing of cables


I recently attended The Show in Newport Beach California, and I asked some experts how to upgrade my cables gradually. I was told to start at the source. I should upgrade the source interconnect first then gradually work my way through the system, and I should hear the difference at each stage providing I am using audiophile quality cables; so I bought some cables at over $600 a pair to try out. My current cables cost $250 a pair.
My system is composed of:
McIntosh C2500 preamp
McIntosh 601 mono blocks
McIntosh mcd 205 CD player
VPI Classic 3 turntable
Nola Baby Grand speakers

I bought two y adapters and connected one pair of new cable and old cable between the CD player and preamp to do an A-B test. I also performed the same test with the turntable but I could not tell the difference between the cables whatsoever. I was very surprised and disappointed at the same time. I could not believe it so I called in others to have a listen whithout telling them what I was doing and they too could not tell the difference.

Has anyone else tried this test? I would like to hear your results.
Am I doing something wrong?

What is your experience in doing A-B testing of interconnects?

ZD you don't know much about me to make a statement like that. Oh wait, so that means I couldn't possibly be correct in anything I say because you've already convicted me and YOU must be correct. LOL Works both ways doesn't it.
No one is debating that inductance and capacitance have an effect on cable performance.

The DBS "paper" is an opinion. Here's a curious challenge: http://www.audioholics.com/audio-video-cables/top-ten-signs-an-audio-cable-vendor-is-selling-you-snake-oil/audioquest-responds-to-top-10-snake-oil-article

Does anyone know if DBS accepted the "Testing" request and if so what were the results?
I'm NOT saying that cables don't or can't make a difference. Cheap, thin, poorly constructed cables can be microphonic, pickup radio waves, and sound like garbage. I've seen it with guitar cables plenty of times.

I question "claims" that can not be substantiated by anything but an opinion and a marketing campaign.

Looking for some proof to the DBS claim I came across another article where Mr. Patrick of Audio Quest clearly states "you can't measure it".

BUT, the good part is that anyone who chooses to "hear" an improvement can certainly pay what ever price they wish for what ever product they wish if they "hear" a difference.

As to Mr. Patrick's claims that selling "millions of dollars of cables every year" substantiating that his cables work I point to Bernie Maddof who had Billions of dollars pouring into his co. LOL

To each his/her own. Anyone compare DBS cables to other expensive non-DBS cables and hear a marked difference either way?
Thanks for referencing the audioholics articles. I know it well and was about to list it myself. In it, they call the DBS system snake oil, and follow up with some scientific info as to why the DBS will make no difference. I see a couple of problems with their argument.

The main issue is simply this: If you read through the articles carefully, you'll see that not 1 of the skeptics so much as laid a finger on a DBS cable. How can anyone make a conclusive statement on the system without actually using it first to see if it works or not? Its silly. In order to claim science, you need to do something scientific. If they would have tried some of the AQ cables and didn't hear a difference, I can respect that. But they're not interested in the truth, they're more concerned about winning the argument.

The other major thing that stands out in the article, is that they're challenging AQ to send them some cables to demo. To me, that sounds like they are afraid that they may be wrong. I say this because if these people wanted to conduct a test of the DBS system, they could easily do so at any time. You don't need AQ to do that. DBS cables are sold in Best Buy. They can buy a pair, test them and then return the cables if they are not happy with the results. What could be easier? That's what most of us here do if we are considering new gear. We demo it. The skeptics can do it too, but they choose not to. I wonder why.
You lost me at the Y-cable....another misguided well meaning audiophile goes down the rabbit hole. Sadly, cables that cost a fortune can and do sound better....as always, the results are system dependent and thoroughly neutralized by pseudo-intellectual, financially challenged DIY types.
