This stream auto-updates     

  1. Past hour
  2. Hoorah !. At last somebody who realises that the cable doesn't know it is audio and therefore can not possibly 'enhance' the music which has been encoded into a bit stream Exactly how does the cable reformatt and purify the digital stream? OMG Pleae don't tell me that you think an expensive HDMI cable can improve picture quality Actually no. I clearly know more about data and audio transmission than most of the respondants. You can abuse me as much as you like, but it will not make me into somebody is so out of touch with reality that he will spend next years vaccation money on a cable that does absolutely nothing more than my $10 cable and then try to justify it bu telling everybody that the violins "sound more alive" ------ Iso Regens ???? Presumably this piece of audiofoolery makes the ones and zeros look cleaner Comparing USB audio to my water supply ? Why not compare it to a box of frogs? Oh, and the single malt whisky and water comparison is one of the funniest things I have read for ages ( I am assuming it was meant as a joke) 1110011 = 1110011 111111111=111111111 etc etc get it. Drag yourselves out of analogue and try to understand digital I notice nobody can explain how this fragile bitstream survives the 2 miles journey to my house as an audio signal Sorry guys, I thank you for your time but I'm out of here looking for a forum here they actually know how audio transmission works. I suggest you do some reading up on how sound is digitised, transmitted and then restored to audio See ya
  3. I think that people get excited at the prospect of a new OS in spite of the inevitable problems it arises...
  4. A good analogy . And perhaps not too surprisingly, the same applies to Digital Video as well .

  6. ZzZzZz no no no....😉 Hi Paul, For keeping everyone awake here are a few minor remarks: 1 Jitter metric: Reading your explanation about how it is calculated, a few posts back, I realized that when dealing with certain waveforms, the reported value may not relate to any physical rms Jitter. Nevertheless, the metric is very useful for improving any alignment. I even tried it with rectangular functions but those are, in principle , not encountered in audio 😊 "A*sign(sin(2*pi*f0*(t+TIE*z(t)))" Jitter metric measures the difference between two waveforms as an error in timing. Existing measures, such as RMS difference and correlated null are both related to the magnitude of the amplitude error, although correlated null is also related to timing. This new measure computes an RMS timing error between the two waveforms. Assuming the amplitudes of the two waveforms are perfectly matched, this number would be the actual RMS jitter. Reported in seconds (microseconds, nanoseconds, picoseconds). The smaller the number, the smaller the overall match error. In effect, that's another number that can be used to judge the quality of the match. 2. Memory issues: Trying to DW oversample big files ( 50 million samples) leads to probable memory issues. To be honest with such sizes I am also having issues with Python 😊 Stopped! Array dimensions exceeded supported range. 3. THD: It seems that the Harmonic reported values (H1 ,H3, H5,...) are scaled with different parameters that the ones currently set: windowing, FFT size,... I was expecting to retrieve more or less the levels shown in spectra but this is not the case. 4 Curve Overlay: The curve overlay is static, meaning that one needs to keep same curve parameters before and after. Rgds.
  7. Are you sure about the PhD because there’s an awful lot of flawed logic here? A digitised stream isn’t ones and zeros....it oscillating voltages. A dumb piece of wire doesn’t detect or decode anything, it merely transmits the voltage stream, either with or without interference. There’s no need to differentiate print from audio streams, they’re either handled with or without additional noise being added.

    HQ Player

    Can you send me email with screenshot of your settings and HQPlayer log file? Also make sure that the Amanero driver is not enabled as output zone in Roon settings. Otherwise there will be conflict.

    HQ Player

    Finally upgraded to HQP4 but I’m seeing a problems that others have encountered: I cannot get HQP4 to output DSD no matter what I try in the settings. It converts both PCM and DSD files to the sample rate in the PCM setting although I clearly select DSM as the default output. Using the Amanero Combo 384 driver for my Lampizator DSD DAC. The AISO driver does not produce any sound, Roon gives a message that it lost control of the audio devise. With WASAPI it converts everything to PCM and cannot get a DSD output regardless of the output default setting being set to SDM. Please help as this is frustrating.
  10. I figured it out it's the laptop I was using it's too underpowered. It's a HP Stream I had lying around that I cleaned up only for Amazon Music but it's too weak. I used my Pixel 3a as the source and no skipping or stuttering even with the same 10 ft cable.
  11. Water coming into your home is perfectly potable. You can drink it, cook with it, make tea with it etc. Can it be improved? Of course it can Can you detect the impurities? Of course you can. Can the impurities cause damage? Of course they can Can a piece of hose improve the situation? Of course not. Can a special piece of hose that’s been specifically engineered and prepared to treat the water make a difference? Of course It’s no different with incoming data streams. They can go directly to a printer and they’ll print, or to an Audio DAC and they’ll play music. But exactly what happens when you clean up the water? You get better tea without the scum, washing machines without the limescale and in data streams you get better music without the HF interference, phase noise and jitter. The difference between analog and digital is that in analog its difficult to clean up the musical signal without negatively affecting the outcome, whereas in digital, reformatting and purification of the digital stream brings only sonic benefits. Water comes into the house with a variety of minerals. A 50cm piece of pipe can clean it up almost completely despite the miles of piping its travelled through. A digital stream is no different in that it too can be cleaned and purified. Take a contaminated data stream and pass it through a variety of different USB cables. Hear a difference? Unlikely. Why? Because the contamination of the stream is already so profound that a little more will probably go unnoticed. But clean it up so it’s fairly pristine and you’ll immediately notice when you add back jitter and noise, vs listening to it clean. If you don’t believe me try this. Buy a bottle of spring water and a bottle of single malt scotch whisky. Now prepare 2 glasses, one with 50% whisky and 50% tap water and the other with 50% whisky and 50% spring water. Taste both and tell me which tastes better. The level of contaminants in the tap water is in the parts per million and has a flavour strength of almost nothing compared to the whisky, yet the spring water tastes superior. Why? Human taste is very refined and has no problem detecting trace contaminants. What else will you notice? The whisky with spring water seems to have a far more complex flavour and tastes way more refined. Why? Human taste is very refined. Don’t believe me? Do the test blind so you don’t know which whisky you’re drinking and simply pick the one that to you tastes better. There’s only 1 proviso. You can only do the test once, with fresh taste buds as your ability to differentiate very quickly disappears as your taste buds acclimatise to the strong taste and lose sensitivity.

    HQ Player

    HQPlayer Desktop, regardless of version, is not interoperable with Audirvana. Other than possible drag-and-drop, which may work (never tried that one).

    macOS catalina

    OK, never seen such here. Not on the web page, or in the store app. Only new hardware. Do they really sell over 2 - 5 year old discontinued hardware models there? I have 2011 Mac Mini and have always kept it up to date. Now it is stuck at High Sierra because Apple has discontinued support for it. So now I will recycle it, it is anyway just a dual-core i5. To be replaced by the 2012 iMac that just got retired from development machine job, which is running Mojave. I will eventually replace it with another new iMac so that I can run Catalina and newer. macOS has been getting better performance-wise. I don't care about emojis, but performance and features of the core OS has been getting better. For example HQPlayer cannot run on El Capitan because I'm using OS features Apple added in Sierra. You probably cannot even open the DMG on El Capitan, because it is compressed with a more efficient compression algorithm that is not supported by older macOS versions. Next release is limited to High Sierra, because newest development tools don't support older versions anymore. Eventually I will also drop support for older hardware models for performance reasons. Things they talk about in launch events are such like emojis, that are visual and something everybody can see. Sometimes they also mention other things like APFS. Since you are using SSD, you certainly should be using APFS filesystem on it, instead of ancient HFS. They also make lot of improvements and new features to the core OS itself, which are directly visible only to developers. They don't talk about such in the launch events because everybody else except developer would be bored to death listening it.
  14. Hey, sun shades at the Lagrange point L1 is what I'd suggest. Get the material from moon mining to build and put it in place. Much less of a gravitational well operating from the moon. Blocking 2% of the sunlight will counteract all the carbon increases in the atmosphere. Best plan to put into place if you aren't some maladjusted fearfully panicked northern European teenage girl. Maybe someone should point it out to her as a solution. Our future is so bright we have to wear shades. We got it made in the shade.
  15. I would like to specify something about updates in Audiolinux: The updating is done with 1) Audiolinux menu 2) Kernel. This is compiled by audiolinux with some changes if necessary (Note: it could be necessary a full system update) 3) System update, not controlled by Audiolinux. This is normal archlinux update. We are not responsible for any problems that may arise. For example the last system update is problematic for normal users. A normal user does not need to make a system update. Audiolinux menu update is enough A new Audiolinux version is released every two months with full package update, if the user want to reinstall the OS. Single packages like HQPlayer, Roon and some other can be updated from terminal this way: yaourt -Syy hqplayer-embedded hqplayer-network-audio-daemon With the last menu using pamac instead of yaourt pamac build hqplayer-embedded hqplayer-network-audio-daemon Note: from version 2.0 I will add an option for HQPlayer update.
  16. @sicher I've told Alex directly that when Uptone's first Regen made my humble office system (a Denon all-in-one) take on Naim-like qualities in PRaT, and add bass like I had never heard from digital, I was relieved I didn't need to pony up for a Naim Supernait like I was originally planning! Instead, I upgraded my Regen to an ISO Regen and my LPS-1 to a 1.2. (Naim need not worry–I'm still thinking about a Supernait now that the 3 is out.) With consumer and audiophile gear alike, cleaning up digital signal and power together is likely to yield strong improvements, and this is what Uptone delivers at a enormously agreeable price. Happy listening!
  17. I have made a new set of measurements with the new version today and I'm getting around 4.5dB clipping. My host/controller app is Audirvana 3.5x on Macbook Pro sending to (uPnP) MicroRendu client. The issue is, even when I reduce the DL2 plugin headroom by 5dB, it does not stick. It reverts back to 0dB when Audirvana is started again. Not sure if this is Audirvana or DL2 plugin issue.
  18. Forwarded PM ,please check
  19. I take TAS, HiFi+, Stereophile, HiFi News, HiFi Choice, and Australian HiFi. All digital. The last time I moved, I had to throw away more than 500 pounds of back issues of audio magazines! Every month I get new issues of all the above, and my iPad doesn’t gain one ounce of weight. That’s all the justification I need to to transition from print to digital!
  20. Not an expert? In this thread you wrote: That sounds like the tone of an expert.
  21. I did “the bridged” approach as well as the WiFi/router approach, namely both MacBook and sMS 200 were connected to a WiFi router which was attached to a HDD using USB. Both approaches sound great and superior to if either MacBook and/or sMS200 were connected to the same router with Ethernet cables. The difference between “the bridged” approach and WiFi-router approach lies in the former sounds a tad bit more glare on the trembles therefore more exciting to listen to whereas the WiFi-router approach lacks such a glare on the high-frequency range, but sounds more real to me compared to the classical music I listened from concert.
  22. Not at all I'm still getting use to my new Lush^2. I've tried 3 settings but unwilling to comment yet. It does appear most have settled on a setting for the time being but always another option. Robert
  23. Yep. I was out of town so grabbed that off of the AL site. "System update" should do it.
  24. Ok... Questions: 1- Why does it improve SPDIF (toslink or otherwise)? 2- Do you buffer and reclock? 3- If you buffer and reclock, how do you ensure that your buffer is never too full or too shallow? Do you make sure to run the clock slower than the input? Sorry... Not an expert, but certainly curious.
