    Review and Measurements of IOM NCore Pro PWR Amp

    With the NC252MP it is exactly a matter of sticking a module in a box and you are done. The Nord NC500 based amplifiers are not like the amplifiers built with NC252MP. No alternative power supply, no custom input buffer, etc. You literally bolt the module into a case and connect your power...

    Review and Measurements of Emotiva XMC-1 Gen 2 Pre/Pro

    No this does not fully explain why these AVPs are measuring so poorly compared to $99 desktop DAC.

    Review and Measurements of Emotiva XMC-1 Gen 2 Pre/Pro

    In tests performed here a lot of that signal manipulation just isn't happening. In fact analog in->analog out is tested (no digital). You'd think the basic digital to analog conversion and output would measure a bit better in a product proclaiming superior sound quality. And what's going on...

    Review and Measurements of Emotiva XMC-1 Gen 2 Pre/Pro

    I did the same years ago and had to switch back (well the avr/avp piece). The streaming era has hit and jriver has no support for it unfortunately (Netflix, Amazon, Tidal, etc).

    Review and Measurements of WesionTEK Khadas Tone Board DAC

    Anyone else have the problem that the board disappears from Windows when the computer sleeps and wakes up? I have to unplug / plug the USB to the tone board for Windows to see it again. This happens with both the UAC compliant drivers and the Xmos drivers from Khadas.

    Charles Sprinkle's Kali Audio LP-6

    Of course I plugged something into them. Like I said I was listening to them play music as I was writing. There's no difference in audible hiss from having an input connected or not. Reason I stated with nothing plugged in is I didn't want anyone to think my source was the cause of the...

    Charles Sprinkle's Kali Audio LP-6

    Just picked up a pair of the LP-6 today and I'm listening right now. To answer your question YES. I'd say every bit as bad as the lsr305 - maybe even worse. The speakers themselves sound great. But with the residual noise with no input plugged in and the input adjust set to 0db on the back...

    Review and Measurements of Topping D50 DAC

    It's my understanding that laptops have a higher potential for better usb power just based on the power supply / battery tech used in them compared to desktop computers. But this could perhaps be a wrong broad brush generalization. Some laptop USB ports are pure junk based on measurements...

    Review and Measurements of Topping D50 DAC

    Did everyone else's D50 come with a power supply? Mine only came with a second cable with usb to dc barrel plug. If Amir only used usb power then everyone's results may vary based on their usb power source. Usb power can vary quite a bit between computers or even between ports on the same...

    Review and Measurements of Topping D50 DAC

    That is not the correct device. The ASIO device for the D50 is called "Topping USB Audio Device". The WASAPI device is called "TOPPING USB DAC". ASIO for Generic USB Device may be associated with a Realtek driver for onboard audio.

    Review and Measurements of Topping D50 DAC

    Has anyone confirmed that they can play to their D50 with any of the 5 players that he mentioned? Until we have confirmation of that it's hard to narrow down where his issues are. We have two apps that have been confirmed to work that haven't been tested on a computer that's having...

    Review and Measurements of Topping D50 DAC

    The Windows drivers for the D50 do some dynamic latency adjustment depending on source signal. I wonder if that is working properly when sending from ASIO Proxy. I don't use Foobar or ASIO proxy where I use my D50, but from my experience with ASIO proxy it's not difficult to get into a...

    Review and Measurements of Topping D50 DAC

    This topic is starting to heat up. This whole section of the forum is all about measurements. Perhaps Amir can do some on this DAC similar to what was posted by the author of HQP for the Pro-ject S2 dac (PCM vs DSD). Many people are choosing this product over lower cost models that...

    Review and Measurements of Topping D50 DAC

    Here's the link to measurements between PCM and DSD on the Pro-ject S2. DSD512 has best performance. Maybe not significant, but upsampling outside the DAC and sending DSD512 improves measured performance. The next post shows J-test between 24/44.1 and 24/192. Yes these are not from the...

    Review and Measurements of Topping D50 DAC

    I don't follow your logic. Using DSD has nothing to do with adding information that doesn't exist. It's about setting the DAC up to achieve the best possible analog output. The DAC is upsampling PCM at least 8x (if not a lot more I don't have the docs handy) then doing SDM conversion. Once...
