Expectation Bias

like all setups, noise and interference are major problems, and currently working on getting an optimum solution to improving the optical waveform characteristics - 'jitter reduction', is the bottleneck, right now.

Maybe start by replacing the low end CD player you use to reduce the jitter to the setup. Investigate known players with low jitter as a start, and then purchase one. Problem solved with the source. If you want to go to computer use to the Alpha USB converter to the Edifiers via coax. It has known values for jitter reduction and well documented. 

 

"Two key factors combine to achieve the excellent audio performance of the Alpha USB; the unprecedented degree of electrical isolation between the USB input connection and the digital audio output and the very low noise/low jitter performance of the individually tested audio output master clocks".

The room treatment thing is required, because the accuracy of the playback is sub-par. And anything you do to reduce the obviousness of reproduction anomalies will help, because the mind has to work less hard to hear what matters, the music. A fully capable replay chain doesn't require such crutches, because the integrity of the presentation is then good enough for the mind to 'see' the illusion without the extra assistance of an 'optimised' room.

Frank, You have neither of the attributes you mention.

Don't follow ...

Trust me, I don't follow a word you say. Maybe get rid of the crap CD player as a start. Then again, 300ps of jitter is no problem for your solution. We just need to see the measured results to confirm it works. All based on subjective science of course. 😁

For somebody who claims to be on the side of science, you seem not to realise how silly what you just said is ... if you have a variety of CD players, as input to some system, one of which has the worst possible jitter characteristics you could imagine, and another one, is effectively perfect in this regard, and the others are in between - the goal would be to eliminate any audible differences, irrespective of player was used. And to you, that is a "fake idea", .

Until yours materializes, it's a idea.

We have different goals. You just want something that works, that also measures well. I want to understand what makes a system work well, and how to do that in the most cost effective way.

Frank, that is the most ignorant thing I have read repeatedly from you of those who disagree with your method. 

 

"We have different goals."

You don't know what my goals are nor a large majority of people on the forum. I never confided in you regarding them with my system.

 

"You just want something that works, that also measures well."

You want a $400.00 pig to look like a silk purse. It's your system and you like it, that's cool, but don't TELL me what I am after. 

 

" I want to understand what makes a system work well, and how to do that in the most cost effective way.

What makes you so special that YOU think others cannot achieve their goals. Why such a ignorant statement to others?  Are the people who disagree with your perspective dumb and incapable?

Lots of reverb, fattening the voice ...

That only reenforces the fact that the room is a part of the replay chain. Change the room and you change the sound heard, ie the sound characteristics have changed.

Quck Frank, go and fix all his cables.

Which one would Frank fix first?? 

[Racerxnet]

Possible 15 amp circuit with 20 amp recepticles. And 30 ft of cabling.

Actually, the fun thing to do would be to have access to the rigs of some of you people, for a day or so, and work out some of the easy to fix, obvious bottlenecks to getting better SQ from them ... of course, I wouldn't get any thanks for doing this, .

I think having access to your setup first for all us novices would be the best start. All might have a baseline to run from...... Maybe we can teach you something about audio reproduction.

[Racerxnet]

Come on Franky,

 

Show us the magic rig. Give us a taste of your secret sound sauce. 🤪 Invite us over for some samples from your collection. We would like to reciprocate your desires.

I posted an article form the late 70's - do all amps sound the same. Basically, DBT testing then showed people couldn't tell which amp was playing. It was a crap shoot if they could tell the difference.

 

This is what Frank is afraid of. That all his 'tweaks' will end up a big 'nothing burger'.

Or a shite sandwich.

Anyone ever see a wiring harness assembled in the automotive industry? Nothing is soldered, and yet the connections perform very well over the long haul. If engineered correctly, soldering will not provide any benefit. The new CX50 and Cross AWD vehicles at the plant are plug and play with crimped connectors. 

[Racerxnet]

Confirmation bias says solder them.

And the snake oil companies will send you a prayer of gratitude, for confirming that their market will happily sustain itself, indefinitely - why get meaningful answers, when you can just fork out money, for a little bit of expectation bias food .

 

One can either get realistic SQ from recordings, or one can't. I've pointed to various people who aim for this, or have achieved it, using their own methods; therefore, these people are deluded, just like me , or are getting a real buzz from superior sound reproduction. If people need to feel that others can't get better results than they personally do, so be it - however, a reasonably intelligent individual would be curious about whether they could advance their understanding, and improve the standard they are getting. Which is exactly what the friend up the road did.

 

 

The only difference between them and you are the dollars rolling into the bank. The confirmation bias between the bogus manufacturer and you are the same. Get people to believe you made a improvement without verification. Carry on.

I will say it one more time, please stop Frank.

Frank knows the cause is lost, its something for him to do. He keeps babbling and the troll gets fed.

It’s helpful to talk about specifics. Do a few examples come to mind?

An example might be a wooden "grounding box" with some copper bars and rocks in it.

That's an idea. Do you have a link? 

 

I'm serious, it really helps to talk about specific items. Otherwise we can all get a bit carried away and make some issue seem larger than it really is.

 

 

Sure,

We use different layers of metals mixed with minerals to create a Para, Dia and Ferro magnetic  galvanic point that acts like a concentrated piece of Earth.
By changing the metals, minerals, size, weight, case construction and differing conductors we get several
levels of performance and types of groundingboxes.
Imagine the construction as a battery, but opposite. Instead of create and send out, it pull back and consume.

A box of rocks and a empty wallet. Some stripped 12 gauge Romex and plywood construction. Oh, and some copper bars for good measure.
