Yeh not all batteries are created equal unfortunately, so there might be a lot of noise coming from the electronics. I haven't tried this myself but apparently LiFePo4 batteries with good electronic controllers are the way to go?Tried batteries but found the electrochemical noise intolerable. Have you tried solar panels & super capacitors? Unbelievably good!!
Hi @onlyoneme just as a matter of interest, and not trying to be funny, what is the level/bar/measurement a dac needs to hit to be regarded as audibly transparent.Looking for a transparency would be like looking for a non-existence. But I can assure you that if 2 devices indicate being audibly transparent in the measurement with a particular test tone, you will not hear the difference when listening to this test tone.
OK, think I get what you are saying. Is it like taking a 'helicopter' view of a series of test results and from your experience testing knowing roughly what this would translate to in terms of performance in your own system?It's arguable especially when talking about being audibly transparent in general. A bit easier for particular tests but rather in terms of prediction whether the result suggests audibility or not, than setting exact audibility thresholds.
Like what, for example?we cannot measure everything that matters to SQ
They are informative and specialized, but if you mean that they do not make a coffee, then I will agree - they don't.for example frequency response curves have many limitations, similarly SINAD measurements or equivalents are also typically not very informative.
It's not their purpose. They are made to let evaluate device performance under some circumstances.it's because we don't listen to test tones in practice..
A jitter can be analyzed in both time domain and frequency domain when needed.these routine measurements contain very little information about the accuracy of your system's sound reproduction capabilities in the time domain
@onlyoneme well, to be specific: we don't have reliable measurements to apply to things like- macro/microdynamics, soundstage, realism in imaging, "weight" of a sound (the feeling of it being a live performance).Like what, for example?
that's a fair point! i can see your line of reasoning and i agree... i wish it were that simple.Inside THIS hobby I give a s...t for the "why". The "what" matters!
All these things are part of the perceived sound quality, an impression built by the brain. None of it is a factor which defines the ability of the device to reproduce the content faithfully, the objective metric of sound quality.macro/microdynamics, soundstage, realism in imaging, "weight" of a sound (the feeling of it being a live performance)
You are assuming measurements are perfect and that anything that cannot be measured is imagined. That is a gross overestimation of the measurement ability we have.All these things are part of the perceived sound quality, an impression built by the brain.
No, I'm not.You are assuming measurements are perfect
No, I'm not.and that anything that cannot be measured is imagined
Sorry. I missed this post."I can promise you that Wiim devices do NOT run on the 5v USB supply!" can you enlighten me how the Wiim Pro /Plus utilizes the 5V USB power to drive the digitial board? I noticed the audio board has two 4700µF caps. Thanks
That also depends on the resolution of your system and your taste. With my modest DAC / Headphone Amp driving my headphones I found the WIim Pro powered by a linear power supply from Audiophonics gave a more pleasant and more natural sound. I did not have the possibility to listen first before buying the LPS, luckily it did turn out to be a worthwhile improvement in my situation.I've just wasted a good hour going back and reading this entire thread. And I'm still none the wiser. Do I need to buy a better power supply for my WiiM Pro Plus, use an old Apple USB power supply, or just crack on with the power supply that was in the box? Which sounds fine so far, to my ears.
Interesting - how much do these things cost?That also depends on the resolution of your system and your taste.
