    Surprise findings on Ethernet cables/cleaners/reclockers

    I think I will retire here again. I don't want to be discredited by people whose horizon only reaches a SINAD value. I have not offered anything here or have to prove anything here. The thread was started independently of me here. If you are really interested in bringing some light into the...

    Surprise findings on Ethernet cables/cleaners/reclockers

    Link should be fixed. I don't see myself in a debt of gratitude or trying to prove anything to you. It is up to others to research on the analog side, since I am not a specialist here. I can only point out where sound influences come from via the Ethernet path. If that is not enough for you...

    Surprise findings on Ethernet cables/cleaners/reclockers

    Some more words for those for whom the subject is new: The sound difference is not caused by influencing the data signal. This is quite bulletproof over Ethernet as it is a differential signal. But with the differential signal also common mode noise is transmitted, which gets into the ground of...

    Surprise findings on Ethernet cables/cleaners/reclockers

    Hi all, I just saw this thread about my work! Will join the discussion later in more depth as I am currently time limited. I've been a bits are bits guy for a long time, and had granted myself a very long time against the claim that Ethernet can affect sound - until I heard it for myself and...

    Is Digital Audio Transmission Analog? [video]

    I've done blind tests which confirmed my hearing. Easiest way to test differences of cables is to test two identical unshielded cable, but with one you have to strip the outer cable jacket and remove the for 100baseTx unused blue and brown pair. With this test, my faith in the irrelevance of the...

    Is Digital Audio Transmission Analog? [video]

    Hi tonycollinet, you might be right about your grounding explanation. But also think about demodulation of HF. The whole problem with this is that I think this is the only valid explanation of how different CAT cables or switches can affect the sound - as mentioned above, I accept that and can...

    You are right - this is what EMI test measurements are doing

    Is Digital Audio Transmission Analog? [video]

    One end to USB ground an the other to measurments ground plane, solid aluminum plate 100x50cm that is grounded. streamer is ungrounded and isolated on the aluminum plate. I make no claim that the measurements are correct in absolute terms, but in relation to each other.

    Is Digital Audio Transmission Analog? [video]

    The interferences added by Ethernet can be over 100mV. I've been researching this for a while. I hear differences myself with different switches and cables, but I can't accept all the explanations, like Ethernet jitter, for this so far. If you are interested, here is a Google Translate link to...

    Is Digital Audio Transmission Analog? [video]

    Horizontal scale: 12.5MHz for the first plot, 1.25kHz vor the second. Vertical scale for both: 10dB For validation here a plot with a self constructed cable and Ethernet with filter effect. No, these interferences don't come Frome the streamer (Stack Audio Link II) itself.

    Is Digital Audio Transmission Analog? [video]

    FFT 0-125MHz Blue FFT is USB Ground without Ethernet Link. Pink with Ethernet Link. White is difference, so the noise added by Ethernet. And here in the audio frequencies: FFT 0-12.5kHz

    Is Digital Audio Transmission Analog? [video]

    Haven't said anything about that this has something to do with sound differences. If one would deal a little bit more intensively with the matter, then one would know that apart from the differential signal also common mode interferences are transmitted via Ethernet. The galvanic isolation is...

    HI, I've been dealing with the topic "Ethernet sound" for a long time now and have also made various measurements of switches and cables...

    Review and Measurements of RME ADI-2 DAC

    No, I think the extra pads in the remote are there to produce a better sound. o_O

    How to evaluate a ELAC Navis bookshelf (powered speaker) versus the KEF LS-50 Wireless 2 (active speaker)?

    So if you label the KEFs as a soundbar, then it really is of no help to you. Get happy with any pieced together setup believing it will sound good.

    How to evaluate a ELAC Navis bookshelf (powered speaker) versus the KEF LS-50 Wireless 2 (active speaker)?

    Sorry that I'll get in touch again. I really do not understand your position. You want to play Tidal Master on maximum resolution - So you need a DAC with MQA capability connected to your MAC. The RME ADI 2 DAC has no MQA capability. The LS50 W II can play Tidal Master MQA on maximum...

    How to evaluate a ELAC Navis bookshelf (powered speaker) versus the KEF LS-50 Wireless 2 (active speaker)?

    So here are my final words in this thread: Elac Navis ARF-51+ RME ADI 2 DAC sounded worse then KEF LS50 W I sounded worse than KEF LS 50 W I + Sub sounded worse than KEF LS 50 W II + Sub All regarding jazz with focus on presentation of instruments (guitar, piano, drums) and vocals. TV stuff i...

    How to evaluate a ELAC Navis bookshelf (powered speaker) versus the KEF LS-50 Wireless 2 (active speaker)?

    just to think about: i am assuming that the guys from kef with all their experience, their measuring devices and their studios can manage a better integration of amp, dac, Dsp and streamer than i can do only with my ears and limited tools. not to mention that cables, contact resistances etc no...
