The identical external low-pass filter circuit for the CS4392 than for the CS4391 in the datasheet of the former was perhaps considered as a feature, to point out that it was possible to replaced the CS4391 by the CS4392 in existing designs? The post-DAC filter on the evaluation board for the...

Thank you for this thorough review of the Myriad Z210 CD player, NTTY! The measurement results are very interesting, indeed. The peculiarities of the Cirrus Logic CS4392 DAC chip are obvious and probably explain the very long career of this old chip (still in production as of today after 25...

Around the year 2000, as an old teenager and a very young adult, I was very much influenced by the subjective gear reviews published in French music or Hi-fi magazines when I bought my first Hi-fi system, because I was inexperienced and uneducated (I have studied in law, not science or...

It has to be said that no generalization can be drawn about the practices of the many different classical recording labels. Some do what you described, some don't and use much more simple microphone lay-out and some even still record 2 channels audio with only a simple pair of microphones.

Do not hesitate to contact NTTY to obtain an image file of his test CD to burn on a CD-R: https://www.audiosciencereview.com/forum/index.php?threads/test-cd-for-measurements-of-cd-players.58046/ ;)

Those excerpts you have opportunely selected illustrate the main issue with this 2001 article, which still regularly pops up whenever the phrase "1 bit" is employed on audio related Internet webpages. The non-technical lexical field about feedback the authors use in these excerpts says it all...

The Pioneer DV-578 uses Burr Brown PCM1742 DAC chips which don't have any DSD input, so conversion to PCM necessarily happens.

Yes, the DV-578 (AKA as DV-575 in other markets, notably in Europe) do. The decimation of DSD into 24 bits/88.2 kHz PCM is done by the ubiquitous MediaTek MT1389 decoder chip-set. The same chip-set also generates the master system clock for the DAC chips (Burr Brown PCM1742) from a 27 MHz...

That is a very interesting observation. Do you have take note of or remember the value of the jitter at the beginning and after the 15 seconds elapsed time?

Paul Miller has written about the first iteration of the Legato Link Conversion in the issue #112 (page 78 of the pdf) and issue #113 (page 17 of the pdf) of Hifi Choice.

Is this a teaser for a future test ? :)

Thanks for this set of measurements, RedFox ! The behavior you discovered has a very simple explanation, I think: this unit must uses a custom interpolation filter Pioneer called "Legato Link". On more recent Pioneer players, this feature can be disable, but on this DV-717, apparently not ...

The difference between 2.5 V and 2 V is not small at all. It corresponds roughly to a difference of 1.9 dB. It is very well established that a difference of level as small as 0.2 dB can be reliably detected by many people in sighted listening as well as blind tests as a difference in the...

I am in awe for this disc : Pierre Boulez, Livre pour Quatuor révisé (Book for Quartet revised). Revised, in this instance, means that Pierre Boulez has worked closely with the member of the Diotima Quartet to... make his early work, composed when he was at the age 23, even playable! A...

I just discovered some interesting efforts made by Paul Miller back in the '90s to assess the susceptibility of amplifiers to RFI. They were published in Hifi Choice and can be read on the marvelous Worldradiohistory.com website. Paul Miller named that measurement 'Broad-Band Radio Frequency...

Point 2 in the above quoted tmtomh's message is the most important, to my mind. The most important decision factor when dealing with SA-CD is access to contents. Especially multichannel contents, because SA-CD is multichannel capable. As far as trying to draw an equivalence between DSD to PCM...

Yes, there are more than the digital format itself that could explain an eventual audible difference, hence the precautions that have to be taken in order to assess two disc formats in order to be sure that only one thing is being compared at a time and not that two or more different things are...

By reading this old ASR thread, we learn that the Behringer Studio XL is some sort of an ersatz of the Mackie Big Knob Studio+. The Mackie comes with a proper user manual, with explicit warnings, notably about the use case of the XLR side of the combined XLR/TRS input jacks (especially related...

Possibly. But, the above quoted specifications are subject to interpretation. Neither the specs sheet nor the serigraph next to the combined XLR/TRS input jacks or the connecting diagram page 15 and 16 clearly state that the XLR side of the combo input 1/2 is linked to a different input...

The user manual, with complete specifications on page 45 and 46, can be read here : https://mediadl.musictribe.com/media/PLM/data/docs/P0E86/STUDIO-XL-&-STUDIO-L_QSG_WW.pdf To my mind, almost nothing seems to be properly documented for such a relatively complex device.
