    Duevel Bella-Luna "Omnidirectional" speakers

    Wonder if you have plans to review speakers such as these - https://www.duevel.com/Produkte/EBLdia.shtml Interesting to me, especially since they look so artsy :) ...And also how "omnidirectional" measures.

    Roon + Tidal in exclusive mode vs. Spotify

    I believe this answers it - https://www.audiosciencereview.com/forum/index.php?threads/rant-newish-audiophile%E2%80%99s-terrible-first-experience-with-%E2%80%9Chi-res%E2%80%9D-on-windows.13587/#post-410656

    Roon + Tidal in exclusive mode vs. Spotify

    Hello, So I've read here that same content isn't discernable between Tidal and Spotify. I wonder, is Tidal HiFi/Roon + Tidal HiFi in Exclusive Mode is measurably different (better) than Spotify which goes through the Windows audio stack? Further assumptions: Windows audio device is set to...

    Help my understanding of Digital Volume levels

    Thanks, makes sense. Sharing more information I've gathered: I've tested Roon with Tidal Hifi and it is getting 44.1 from Tidal (might be content dependent). So I guess 44.1 is the best option for me. Also -VoiceMeeter (potato) doesn't seem to match to source app's sampling rate even if I use...

    Help my understanding of Digital Volume levels

    Do you think going through VoiceMeeter change something in this regard? Does it means VoiceMeeter, if used and to be optimized with Spotify, needs to be set with "Preferred Main SampleRate" of 44100Hz? Will that be at the expense of other application sources which play higher sampling rates? Is...

    Help with Digital Bass Management summing formulas and other considerations

    There is an additional handling of the LFE channel, and perhaps different summing formula. But anyway I wasn't saying that they're that different, just to start with getting the 2.1 formula right and take it from there. Perhaps I didn't explain myself... I am familiar with BM concepts...

    Help with Digital Bass Management summing formulas and other considerations

    Hi Guys, Thanks a lot for helping! Why not, digging dipper into my hobby :) Just to clarify - I mentioned JRiver just as a reference. I wrote in the bottom that I'm looking to implement a similar BM scheme with EqualizerAPO that will be available system wide without having to go through the...

    Help with Digital Bass Management summing formulas and other considerations

    In a JRiver thread there was a discussion about JRiver's BM formulas, for example - L^2 + R^2 + C^2 + SR^2 + SL^2 = LFE^2, from a post by Matt, JRiver's CTO): The thread continued long and strong about requirements for +10dB LFE attenuation and other important considerations like slopes...

    Science behind claim of MS OS Mixer bypass necessity?

    Would be interesting to compare it to VoiceMeeter which sort of replaces the OS Mixer while also allowing input from multiple sources but in the form of multiple virtual audio interfaces. I use it to get the amazing EqualizerAPO without going through the OS Mixer - Roon/JRiver --> VoiceMeeter...

    Science behind claim of MS OS Mixer bypass necessity?

    *Thumbs up*! Thanks! Are there any conditions under which the sound quality is not affected? I ask since I want to use the amazing free Equalizer APO (seriously impressive project!) but the one thing it is clearly lacking is in its reliance on windows audio enhancements (in itself a clean...

    Science behind claim of MS OS Mixer bypass necessity?

    I mainly refer to shared mode / exclusive mode. But also integrated in WASPI vs. System output (Direct Sound?) vs. ASIO drivers. Is there a difference if no oversampling occure (e.g. content is equal to configured in device settings)? Is the OS mixer volume implementation good? Were...

    Power Bank that is always connected to a charger - effective?

    Apparently some do. Definitely won't hurt to measure :p Btw speaking of batteries, when you test USB power from your laptop... Isn't it sort of battery powered?

    Power Bank that is always connected to a charger - effective?

    But extremely inconvenient. Non of the usb chargers (inc. originals from LG, Samsung, Apple...) have a ground pin. All are just 2 pins.

    Power Bank that is always connected to a charger - effective?

    You are right about doing it right with a good power supply... Just a bummer that they can be overpriced. Here is an explanation I've found about the OP, doesn't look good for the cause: http://blog.ravpower.com/2017/10/danger-and-damage-of-pass-through-technology-for-batteries/ I guess a...

    Power Bank that is always connected to a charger - effective?

    Hi all, In measurements threads, an option to use a power bank for USB powered DACs is mentioned. The advantage - stable power. The disadvantage - having to charge the power bank from use to use / time to time. I wonder - 1. Do we know if, while connected to a wall charger, the power bank...

    Review and Measurements of RME ADI-2 DAC

    RME answered the first one in their forum - https://www.forum.rme-audio.de/viewtopic.php?id=26975 No native stacking for the ADI-2 DAC, but possible with AES/SPDIF multichannel interface like the $257 USB MiniDSP U-DIO8. Also this (from an email) - Q: With AES (external clock) we are now...

    Science behind iFi AC iPurifier - what do you think?

    Interesting logical point! From what I've gathered - not a sink, but a generator of noise in opposite phase to original noise in order to cancel it out. All strictly non-engineering marketing speak and I have no idea how inaccurate it is. If it is working then indeed it is missing specs as to...

    Review and Measurements of RME ADI-2 DAC

    Seems like a dream DAC. I wonder: 1. If it can be stackable for doing multichannel (2 units or more) using the USB ASIO driver, the ADI-2 Pro manual hints little about this capability ("multi-interface", if I'm not confusing it) and the ADI-2 DAC hint even less. Could then be just about the...
