    What does this unit do exactly?

    I don't know yet about my friend's chain. I assembled my system with a Raspberry ethernet connected to my PC, soon to win a dedicated server. For now I'm using my PC as server. My program of choice for the Rasp was Picorepalyer with LMS, because I didn't want to use a cell phone as remote...

    What does this unit do exactly?

    I would never use a PC without an external DAC. Any PC or laptop output is noisy. Please suggest options that are affordable. What about this one: https://www.amazon.com/dp/B07D412VLB?tag=techhivecom-20&th=1&psc=1&ascsubtag=US-003-3050398-002-1441458-web-20

    He wants to play music on his power amp, replacing the CD.

    What does this unit do exactly?

    A friend of mine asked about this unit and I can't exactly pin it or explain what it does. https://www.ebay.com/itm/Lossless-Music-Player-HiFi-USB-DAC-Audio-Decoder-Optical-Coaxial-Analog-Output/283309743758?hash=item41f6939e8e:g:nA0AAOSwsDZcGkaY It says it's a "music player", which is quite...

    Topping D50

    Some time ago I had read here someone claiming that the Topping D50 DACs were fed 3.3v separate supplies using linear regulators, fed directly from the 5v input supply. The output analog stages, on the contrary, used a DC-DC chip, that converted the 5v input supply to +/-8v. I believe the latter...

    No, I do not see any metal cans. Can you tell me the name of the seller? Then I may find him.

    When shall we have the prices for the big sale on aliexpress coming on 11/11? Maybe they also go down on the D10.

    Options for Topping D10 DAC below $100

    Audiosciencereview serves just as a first reference, or one of them. They do not do subjective listenings, which I think are a must in audio equipment. I do believe in both things, objective and subjective tests, you can't dismiss the latter as many people do. Measurements do not tell you how...

    Options for Topping D10 DAC below $100

    I already have a Topping D50, which I use for my audio network. Now I would like to try a good quality DAC on my PC audio output, connected to USB. One option, recommended by many, is the Topping D10, selling for $90. The DAC chip is the ESS9018. Are there other alternatives, below $100...

    Topping D50

    The question is not very low noise from the supply, but audio quality. How the power supply affects or not the audio quality.

    Topping D50

    I think you are missing the focus of my conversion. All small DAC share the use of switching supplies, usually from the 5v coming through USB. That I want to eliminate and use regulated linear supplies for the output stages, or even the DAC itself if necessary. Using external outputs would...

    Topping D50

    Yes, the DAC chip comparison seems quite interesting to me, and I would love to listen to such a thing. Balanced connector or output is not an upgrade, but the D70 does have one thing that makes it interesting: its power supply seems to be all linear. I say it seems because I would have to...

    Here's a Topping D70 subjective review I found to be particularly interesting, and it does have one comparison at the end. https://soundnews.net/sources/dacs/topping-d70-dac-review/

    Topping D50

    Yes, one aspect Audiosciencereview gives little, or should we say NO attention, is subjective listening. Particularly comparing tested units with other similarly priced ones or even lower or higher priced ones. The Topping D70 certainly looks interesting, not because it has balanced outputs...

    Topping D50

    Apparently Audirvana and Foobar are players. This is not really what I'm looking for, even if I could use any of them. What I want is a way to play ALL audio from my PC through the external Topping, if possible bypassing whatever is not essential from Windows to play the audio. Any idea what...

    How to connect HQplayer to a DAC?

    Sorry to revive this thread, instead of opening a new one. Perhaps I should do so. My successful recent experiments with an external audio manager, using a Raspberry, fed by Ethernet cable stream, and a Topping D50 connected to the Rasp output, all controlled by PiCorePlayer, turned out to...

    Topping D50

    Is anybody using the Topping D50 straight from the PC USB output, with Windows? With which program?

    Topping D50

    No thread yet, maybe when I modify mine. Yes, you bypass the whole output stage, which is powered by DC-DC supply.

    At the end of what are you using all this? A DAC? Which one?

    Topping D50

    Yes, some issues. The one I have right now is how to make the Raspberry USB output work to feed the Topping. For some reason no sound comes out of it. The PiCorePlayer configuration is done through the web, and one thing you can select is your audio output. Only a few Raspberry plugable DACs...

    Has anyone used or is using a Topping D50 connected to a Raspberry running PiCorePlayer?

    Topping D50

    Of course Topping is using a DC-DC stage for the output amp stage, converting 5v into +/-8v. Nobody is denying that, on the contrary. That was talked here several months ago. My suggestion was to use an external output stage altogether, straight from the DAC, which can still have linear DC if...
