Computer Storage - Best Practices

[Ralf11]

you mis-spelled unreal

[Ralf11]

some excellent Rioja ---> Gran Reserva??

 

 

somebody should buy up some fiber equipment; stamp Audiophile on it; add Bubinga wood panels and go to town...

[Ralf11]

maybe he says it based on not understanding how buffers work

[Ralf11]

The problem is the dissemination of BS to unsuspecting newbies.

 

I am hardly a hard-leaning objectivist, but I am a scientist.  You will find similar comments form engineers and others who know what they are talking about.

 

But I am sorry if I harshed your mellow - Good Luck on finding a Safe Space (to quote another scientist).

[Ralf11]

I hope you enjoy your anti-5G rally.

 

and what does moriez-muffy have against Spanish wines?

[Ralf11]

I am not talking about measurements and rarely do.

 

But I'll be glad to look at any published articles on psychoacoustics you want to cite.

[Ralf11]

medical practice is not a science - your surgeon will make that clear before he opens you up

 

modern medical practice is based on science (one reason audiophools are not admitted in any state)

 

you might benefit by starting with a cognitive psychology text - I posted one title on here a while back; you can then go take a look at what sensory labs are doing right now -- it will reinforce the need for blind testing

 

sorry about your tinnitus - it is one of many ailments that may mean you can get by with a lower quality system (to look on the bright side)

It has also not been confirmed, and won't be. A single test result proves nothing. That's all there is to say until substantial new information is obtained. Unfortunately, hauling my lab gear to your place isn't practical.

 

oh no - this single test result "proves" to xx level of significance that he could hear a difference in the 2 regimes

 

what we don't know was the cause - unfortunately, software settings differed, and that appears likely to have been the reason; it is certainly the most parsimonious mechanistic explanation

The outputs were bit-identical.

 

Let me know if you're still finding this a difficult concept to grasp, and I'll try to put it more simply for you.

 

 

yeh - while you're at it, give the entire methodology so we can check this unusual result

 

you never did that in the whole, loooong thread

 

 

[Ralf11]

point it out - I read the entire thread carefully

 

more likely is that you don't know how to write up a methodology section - most people don't

[Ralf11]

I am glad that both of the manxx people did this test.  It is certainly a step in the right direction.

 

And that is true even if manxx #1 got lucky, or if some bias was present besides SQ or if the files really did sound different.

 

But if the files do have a different sound then that is an extraordinary result, and further investigation is needed.

No you have a lot to learn, I work with it in the real world with real results, not some meandering thread where people are playing and having a good time, but it is not research, it is hearsay.

 

careful - some of the anti-VAXers on this thread think science and engineering is a "disruptive comment"

 

you must never challenge the muffy army with facts

What are you on about, what DBT's...

I am on about comments to a post yesterday, Not the listening test others are talking about...

 

 Gold Standard DBTs is a stock phrase he has used for years

boy this was tough to follow...

ok, here's a SUSPECTING Newbie... where did the wise elderly end up?
I'm going Mac Mini as transport, USB out to DAC
If bits are bits then shouldn't matter that i do this from internal SATA HDD (and the only benefit of upgrading to SSD would be Speed)

are all those other posts about hearing benefits running OS off SD Card, storing music on separate bus from DAC output type, and trying to run the music off RAMdisk then moot if bits are just bits?

thanks in advance,

a.r.

 

not moot if noise can get into the DAC from a power supply or noise on the AC line; or if noise is transmitted to a susceptible DAC along the USB cable

 

the controversy is about how much noise & by what route (besides the typical audiophool magical thimking)

 

if you follow the precautionary principle (balanced with some avoidance or wallet lightening) then it makes a lot of sense to try galvanic isolation on the USB cable, at least

 

whether you 'need' a special low noise PS (and a LPS or good SMPS) may depend not just on the characteristics of your DAC, but on the type of music you listen to most -- I suspect that symphonic music might want lower noise than say Legends of the Wah-wah Pedal

[Ralf11]

actually, I have a fair amount of experience in the "electronics area" -- not that a Sand storm would know

Has nothing to do with the intended purpose of the thread and with my point. Take a look again at post #1.

 

I certainly wonder about this need in you 'non-believers' that must prove the other side wrong or at least oppose time and again unasked for. So tiring. Did all the numbers crunching erase traits like consideration and courtesy? The live and let live? Reminds me of a bunch of fun-loving guys doing what they do until the bad boys from down the block turn up harrassing and ruining a perfectly good time. I quite genuinely wish you guys found a way to enjoy yourselves NOT at the expense of others, because as I see it that's what's going on here way too much. 

 

There is little for me to add so will now retire from the thread. Sorry for the slight derailment and all the best.

 

You are correct in that marce did not conduct a controlled experiment on A vs. B to make his stmt.  That is called science (in case you skipped high school or something)

 

Instead, he is relying on his considerable expertise in very hi-tech fields.  The US Supreme Court interprets how expertise gets into a trial, and it is weighted more highly than someone without expertise.

 

In my view, if marce is 'guilty' of anything it is being too careful (e.g. importing two noise concerns in batteries from very high level edge of engineering areas into computer audio).

 

people are being re-ridiculed because they ridiculed others first (who are scientists or engineers with extensive experience in relevant areas to sound reproduction)

 

either that or their stmt. evince beliefs that are far, far beyond the pale 

 

Posts claiming that scientists do not have open minds are also off base.  A scientist has an open mind ot new information (data) but it is not open like a screen door in a submarine.  No experiment, no science.

 

Comparisons here to anti-5G and anti-VAXers are completely appropriate.  Sadly.

little relevance

 

this is a core problem - you don't seem to realize that is is completely relevant - that is fundamental to digital storage and transmission

 

if you don't like electronic signals, we can use DNA

 

or RNA

 

 

[Ralf11]

that's fine - the Oppo has a good DAC in it

 

if a concern you may be able to find a way to galvanically isolate the storage unit from the Oppo
