Future of cables!

Very interesting -last night I was with the Luxman representative.  I told him that I recently  finish the old Luxkit 501 amp.  He knew about it, pure class A operation.  I was asking him about what Luxman products today would be in that same sound quality.  He had with him a sample one of the new power supply modules.  He was telling me that Luxman being in business so long has tried about everything design and parts wise and they still get parts sent to them daily for testing.

He then proceeded to inform me that they now use EI transformers over toroidal transformers because they are quieter and tested extensively these results.  Now the two people I was with are electrical engineers and after that conversation they advised me that he was full of it that Toroidal transformers were quieter. That was what I had always thought also.

So go figure!  Technology at its best!

Bigkidz, AFAIK toroidal transformers have very little magnetic flux  leakage and perhaps are quieter under normal conditions, but lack of core gap makes them more sensitive to DC in mains, that can produce noise or even saturation.

Sheesh guys, is this what ya'll do to entertain yourself?  Argue about theory of a misguided science article?  lol  Whatever floats your boat.  I'm going to put on some music and try to forget this conversation. lol

I studied E&M theory, taking all of the courses in it my graduate school had to offer. My qualifier exams took four days, one full day of closed book problems to be solved in electromagnetic theory and I made the top of the class in all my qualifier exams for which I spent over a year cramming. I found out after I graduated the authority I had earned the hard way was no match for salesmanship and charisma by the charlatans who sell such junk science as long grain copper and skin effect which they never bothered to calculate in their market-research derived cable designs. In the job market people with PhD's are discriminated against and in universities they are paid less than minimum wage while sports coaches get seven figure salaries paid for through tuition price gauging.
I think the future of cables will be more junk science at higher prices and the suckers who fall for it more stubbornly convincing themselves they can hear a difference because "double-blind listening tests are unfair,"

Answer me this, Mr. Electronics Authority, why is skin effect even an issue when the signal is not the audio waveform, i.e., it’s not frequency dependent? Furthermore, nobody said double blind tests are unfair. What was said was double blind tests are no more meaningful than any other type of test. They can also be easily rigged, so in that sense you’re right.
