    DAC difference

    OK. I will repeat. ESS chips has filters, e.g.ES9018, ES90318 and many others, especially "high end") Here is the brief description: https://www.diyaudio.com/forums/printthread.php?t=337829 Note that there are no "off" option, so what would be "transparent"? Can anyone tell based on their...

    DAC difference

    Any engineer that develop DAC chips now knows that they need sales and being distinct from those $2 DACs. The "transparency" won't sell, as simple and as Darwinistic as this, despite all good red books. Hence those MQA encoders in DAC chips :frowning2:

    iFi audio iEMatch4.4 - Want to Optimize Your Balanced Listening to the Full?

    IEMatch 3.5 can actually work balanced (amazed me), so with the two balanced adaptors (cost of $20 to $40 total) - the balanced world is yours :)

    TRI earphone impressions - I4 and I3, Starlight, NEW Starsea

    Great impression, Chris! You consistent constructive positivity from TRN to TRI is truly amazing! How does it compare to BTR5? (A purely academic question for me though, my preferred universe is alike of E1DA and Zishan Z4 - engineeing marvels on their own)

    :) if you take your time for it- you mentioned Helicores and then some Eva Pirazzi against good Thomastic (I loved Jargar Superior but our great teacher clearly showed that the A-E transition is not great for young players to my dismay) Recorded up close. I will be happy to be fooled. On my...

    A good reference, and geat studies! I did read ther several original PNAS papers. Do show the power of the blind tests. To distinguish different E strings on the same violin is easier :)

    I am not denying (or defying) red books, or Shannon, Nyquist, Whittaker, Kotelnikov, et al. I am asking how to apply this theoretical knowledge. With respect to this dialog, it feels really regrettable that with so many words, the entropy of your response is very high... I do appreciate your...

    DAC difference

    OK. Let me try one more time. What "definition" exactly? How can we apply it? That would be science - making useful predictions based on the acquired knowledge. That can be reasonably done for cables - first with their resistance, but then with the relation to the properties of transducers and...

    How do I convince people that audio cables DO NOT make a difference

    I have two simple conclusions: 1. A lot of gibberish above. Of course - the modulations are described by AC (characteristic response times and frequencies). Capacitance and inductance of IEM cables are unsignificant to matter, so the IEM cable is just a resistive load. But then... 2. Instead...

    DAC difference

    I would not argue about these numbers, my question is more about "the standards" of violin recording, and you, as a former performing musician would be one of the best to answer. For instance, if we record a violin up close with all the delicate bowing details - attack and release - would it...

    DAC difference

    Everything you write makes sense, but then again, I am striving for direct applicability. In the absence of well-defined specs, to which manufacturers will feel to oblige (and they rather do their best to be distinct and special, understandably), I can only see "transparency" useful as a purely...

    DAC difference

    OK. Got it about the range. How do you define the noise floor, dBs are relative? What about the specs of the absolute noise (microvolts) satisfying "transparency". DAC chip filters produce audible changes, if not right away - then through the amplification chain. Then you can see where we are...

    DAC difference

    I did ask you about specific numbers that can enable one to decisively judge "transparency". Now, before starting to talk "balls", again a specific question to you - for the ESS chip, let's talk ES9038, in particular, for the seven preset filters - which one would be transparent and which would...

    DAC difference

    The digital data may satisfy "transparency" conditions, but what about parameters of analogue signal generation? Do we have a decisive set of parameters? I assume "cooking" as a "working hypothesis" that in order to be tested needs a set of well-defined parameters on transparency, which I have...

    DAC difference

    Great answers! What about the background noise as an important parameter of DACs? That leads us to a point that the circuitry that generates voltage is not that ideal. Can you guide me to the numbers of 55 ps, please. ~10 megabit per min is under a megabit per second of data - what do I miss...
