Tweaks, Cables, and Filtration: Essential for World-Class Stereo Performance?

I completely agree, while the inverse is also true—acoustics cannot do what good tweaks do. It’s not an either-or situation, nor does one negate the need for the other. Acoustics, speaker placement, proper system setup—including impedance matching, matched electronics, proper power for speakers, and proper subjective balance of electronics for speakers in the room—alone will not achieve what tweaks do. Tweaks enable everything else to work that much better.

The relationship between acoustics and tweaks in audio systems is synergistic rather than mutually exclusive. Both play crucial roles in optimizing sound quality, and their combined effect is often greater than the sum of their individual contributions.
What you are doing here is to promote your own products in a way that I (it may just be me..) find rather "strange" and out of place. I am not saying that all tweaks and accessories are not effective, but my experience tells me that the acoustics are way more important than much of what you and others are producing/promoting. To sometimes (but quite often) ridiculously high prices.
 
I tried the green marker on CDs in the 90s. Didn‘t hear much of a difference. But using a bulk tape eraser on my CDs make a significant difference. I bought the bulk tape eraser back in the early 90s from Radio Shack to try for $20. Amazing difference. I had a buddy come over when some of his CDs so we could compare my treated version to his untreated version. The difference in sound to me was like the difference with a poorly tracking cartridge vs a good tracking cartridge.

I have never found an explanation for how or why treating CDs with a bulk tape eraser works. My personal theory is that the laser reader is recreating the square wave from the CD track. At that point the square wave may be susceptible to EMI perhaps. The bulk tape eraser eliminates any stray magnetic fields generated by the spinning CD- metallic inks in the labels perhaps?
Somehow, I knew you would claim big improvements with “tweaks”.

So a demagnetiser improves the sound from CDs treated with such? CDs are made of a polycarbonate base, a thin coating of aluminium covered by an acrylic protective layer. None of which are ferric or magnetic, so it can only be placebo effect (no doubt brought about by a strong belief and expenditure of money).
 
What about expensive fuses? What is the audible improvement and which is guaranteed to provide that? Worth the expense of a new turntable?

I’m not sure which turntable one can buy for $600, unless we’re talking about a Crosley, but the effects of fuses on sound quality are easy to prove to yourself. Here’s the difference between one of the world’s most popular upgrade fuses, the Synergistic Research Purple Fuse, and the new Synergistic Research Master Fuse engineered to be placed in a DAC or preamplifier in a loom of otherwise all Orange, Purple, or Pink fuses. Were we to replace the control fuse, in this case the Purple fuse, with a glass fuse, the contrast would be greater still.

Absolutely. Keep telling yourself that.

I found medium cost power cords not that effective. Higher cost power cords are effective- unfortunately they cost a lot.
Remember, the amp is taking the power from the wall and modulating that voltage to recreate the music signal into the speakers. Yes, amps have big inductors and capacitors but still, garbage in, garbage out.

Tony, out of curiosity, what do you call a medium-cost power cord? What is that number or price range?

I don‘t mean it to be about cost but it comes down to that.

I found mid grade power cords <$800 were so so. When I tried some higher end power cords in the $1.5k and up range then I heard significant improvement. The noise floor dropped which I thought was already quiet and the sound and clarity improved. The whole soundstage improved. The amps, the DAC and then the preamps in that order.

I tried upgraded fuses in my Pass Labs amps (not SR fuses) and didn‘t hear a difference plus the fuses kept blowing. After having a few hundred dollars in fuses go up in smoke I stopped experimenting.

All true, but I said “world-class.” At the end of the day, when you have your speakers perfectly placed, when you have the right electronics driving your speakers, when you’ve got the right cables for your system, when everything is dialed in, when you’ve got your acoustics just so, adding the right tweaks makes an absolutely massive difference that can’t be achieved through any other means. This is my experience.
So … A mere 15 posts in and the thread morphs into yet another SR Infomercial .
Different audio forum … same old playbook !
 
What do we learn from saying “all of the above”?

I have heard someone with more experience of high end than I say that the right speaker cables (which would those be?) will help more than any other cable, power cables next, then interconnects and no difference with ethernet cables. I personally heard no improvement with custom power cords. I’m not saying that one can’t hear a difference, but is a difference the same as an improvement?

What about expensive fuses? What is the audible improvement and which is guaranteed to provide that? Worth the expense of a new turntable?

How many of you have tried using a green marker around the edge of your CDs to prevent stray laser scatter from affecting the sound? Did it make the improvement in SQ that you expected? Wish you stuck with vinyl records?

Considering the parable of “the Emperor’s New Clothes”, I am no-doubt risking the wrath of many (including the OP), but (IMHO) this website is for enthusiasts to find out “what’s best” (in audio replay), not “what’s best” for someone’s bottom line.

In my old system, I had Magnepan 1.6s. I had just met Ted at RMAF and he said I should try three things: SR Black fuse, SR jumper cables instead of the included Maggie jumper, and an HFT on the crossover panel. I tried each one at a time and they all made a difference. A year later I upgraded to 1.7s and added them in again one by one. Again better sound. It was very noticeable.

In my experience, ethernet cables have a huge impact. I recently did a shootout between Blue Jeans and Synergistic Foundation SX Ethernet cables. The Blue Jeans literally sounded broken.

What a bizarre hobby. You have tweak's and audio jewelry vs the WE guys using 60 year old NOS wire both feel their systems are world class. Who's right? Who cares! If you are good consider yourself lucky!

One thing the better power cords have are filters and devices that lower noise.
 
These peaked in popularity during Watergate....

30+ years old and still a great digital tweak.

The above mentioned things are essential.

Hello Todd!

Do you really believe that cable elevators and specialty fuses are "essential"? In your experience is there any way to quantify in some relative sense what you mean by "essential"?

What I am trying to understand is that if cable elevators make an "essential" difference, then what is the nature or the magnitude of the difference made in your opinion by a change in preamplifier or source component?

Ron, if I may, this video—if you listen on your hi-res headphones or through your reference stereo—demonstrates how effective cable elevators can be. Signal is not electricity running down a wire, but rather an electromagnetic field that surrounds each conductor and the cable itself. When the cable is resting on the floor, the electromagnetic field interacts with the floor, and this has an audible effect on the sound, which can be heard as a compression of the soundstage, lack of definition in the bass, and a noticeable loss of resolution. It’s more pronounced in person but still audible on a compressed YouTube video.

My power is noise free. I found that inserting power conditioners into the power line worsened the sound (the more circuits, the less real).

Could we see the views of members who regularly contribute, have experience with some or all of these things and do not sell the stuff (and are not tech/equipment junkies)? Positive Reviews by people I have never heard of don’t convince either.

;) Well that pretty much eliminated most :D

Agreed. Pretty obvious to one who simply cares about the message and not the messenger per se. As a former avid fly fisherman, he's found the right fly and is getting some bites. Hence, the reason for the SR product videos. Yum.

The product videos are a direct way to answer questions. While people are speculating on whether certain types of products can work, the videos themselves offer compelling insight.
