Cable and power cord sound...a journey

If you want to know about a Rotel CDP, then you'd get better results putting that in the heading and asking the question earlier in the post. This thread may get a lot of action, but I'm wondering how much good CDP information will come forth.

It's a journey, Dave. The word's right there in tne heading. You'll have to travel some to get to the question. Pack a lunch.

Folks, I simply cannot buy the argument that cables are all the same or do little.

no one expects you to. Just dont expect anyone else to feel the same way. I formed my own conclusions using diffmaker, null tests, and things of that nature(I have a recording studio with pretty much any sound tool that I need)..my experience was that once I saw the facts in front of my eyes(and ears ),ideas that I had about wire(such as thinking they have an enormous/or any impact) and metal boxes vanished.

I guess we simply differ. I put my faith in what I hear and you in what you test (if I understand you correctly). If what I hear differs from what a test reveals, I still go with what I hear. I just figure the test is flawed in a way I don't understand.

Have you ever seen a ghost? Most folk say such things do not exist. Tests don't show them and they cannot be produced on demand BUT, folk who have seen one just might disagree.

One can only test for what one understands. I know I hear differences in cables. I have no idea how to test for that change.

The facts are that if you try to stretch yourself and put yourself at emotional or 'social group' risk and ask every person you run into if they've had a paranormal experience via explaining your own, sharing, etc... ie, an experience of some sort that does not fit the extant physical model,'science'....you will find that well over 95% of the people in the world absolutely HAVE HAD at least one.

Or more, for most people.

So much for 'science' and 'hard reality' explaining all that is out there.

That's the universe knocking on your door telling you to wake the fuck up.

Like many audio enthusiasts I hadn't paid much attention to building a strong audio system foundation. That is until I attended a HiFi+ setup and tuning seminar at RMAF 2008. Roy Gregory (HiFi+) very clearly demonstrated how paying attention to electrical power conditioning; resonance control of electrical & mechanical vibration; and consistent power, interconnect, and speaker cabling (same manufacturer) pays big dividends in audio playback quality. RG told the group until we carefully address these areas, we haven't really heard our current audio system.

Now that I've addressed my audio system foundation I hear a profound improvement in articulation, soundstage width & depth, instrumental imaging, and impact.

Hey, man. We may disagree on politics, but we agree about the primacy of listening.

If we ever get to hang out, I have a GREAT ghost story for ya, too.

Cheers.

I am a member of SPARS Paranormal, an affiliate of TAPS(The Atlantic Paranormal Society, the group that the show "Ghosthunters" is based around) , I am of course , one of the skeptics on the team. Interesting stuff, to be sure. Grant and Jason from TAPS are good dudes.

The fuses in the DC power supply rails of a power amp definitely can make a different in the sound quality. The fuse on the AC power cord should not be an issue. I wonder which one you were talking about.

Understanding the nature of the fuse makes it quite apparent why this is so. It is a non-linear resistance. At low temperatures its resistance is insignificant, but as the current rises, so does its resistance; at a certain point, its resistance gets so high that it overheats and melts.

I first ran into this about 30 years ago when I purchased a certain amp rated at 80 watts into 8 ohms. The fuses on the DC power supply rails were only 3 amperes. Some math will show that these fuses were getting pretty hot and lowering the DC voltage to the output stage during large signal events, creating distortion. Peak currents to produce 80 watts would have exceeded 3 amperes (4.5 peak amperes at 80 watts**). Changing the fuses to 6 amperes resulted in a noticeable improvement in sound quality.

Obviously, the fuse size is a compromise between protecting the output transistors and compromising the sound quality.

**(Vout for 80 watts into an 8 ohm load = 25.3Vrms or 36Vpeak; which would produce 4.5 peak amperes through the speaker alone...exclusive of other circuit currents)

The more we understand about dimensional realities, the more we have come to the conclusion that the considerations surrounding so-called 3-d reality (linear time, gravity-what you see, etc) are based on group consensus and there is a definite aspect of personal effort involved in that determination that is local to that person.

Ie, you won't see/know it if you don't believe and you will see it/know if you do believe. This would be quite the catch 22 for the skeptics - proofs, etc.

This also plays out in the basic aspects of life, refusing to understand that one's wife or daughter is a ho, or that one's political party choice is no better than any other scumbag, etc.. whatever the case may be.

Same for audiophiles. Does the determination of their being no difference actually create that for the given person? Literally hearing what you want to hear? (whatever the direction it may take)

Questions, questions.
