Hi I need a good DAC for headphones with microphone for phone calls and Android So a simple 3.5 to USB converter would be OK? Ugreen 3.5 to USB is TRRS(CTIA/OMTP) Hi-Res 32bit/384kHz 110dBFS and with extra port for USB-C so for charging or I can plug something extra with USB for 15€...

Hello ASR members, Today we'd like to introduce our latest desktop DAC and headphone amplifier, the SMSL D100. The D100 was designed around a straightforward goal: combining strong objective performance, low-noise operation, and practical desktop functionality in a compact form factor. Key...

In a couple off weeks I will get an DAC/AMP for test that needs: "It is recommended to use a USB TYPE-C PD power supply that supports 20V / 3A with a power output of 60W or higher" A low ripple and noise USB-C PD power adapter or a powerbank could be a solution. Any suggestions? Thanks

...USB spec, the ADUM3165 based ones being the most common inexpensive ones. Some HiFi companies sell things that claim to do something about USB noise via disconnecting power and/or ground after some delay - these are not specification compliant which can cause further issues, and they may not...

My setup is PC with KEF LSX II. My Asrock motherboard is very noisy, I've tried many things but ultimately the only solution seems to be optical connection, which my motherboard lacks. I've found a few USB to Optical adapters, and I would like your opinions on which one to get. DoukAudio...

The Windows 11 USB driver was producing random noise. However, the noise stopped once I installed the Windows 7/8 version instead.

I noticed, just fooling around, that recording 'nothing' from an external ADC with USB out (i.e., nothing connected to the ADC input), into USB in of either of my two laptops running Audacity, produces recordings with low-level noise -- not normally audible, but audible if I record or play back...

How does this work in reality. Is the USB power connection (+V and GND) fully isolated from the analouge output for both power AND data connections? No possibly for PC ground noise from either connection to flow to analogue output ground? IE have you implemented an internal USB isolation system?

The noise has to come from the USB, RCA is clean but not headphones and balanced. I have an IFI USB filter (paid only 15 euro), wonder if helps anything at all.

No, IT wouldn't create noise in the analogue domain.

This is a review and detailed measurements of the Cubilux 7.1 USB Surround DAC and line/microphone input. It was kindly drop shipped to me and only costs USD $32. From the pictures I assumed it was desktop sized but as you see, it is tiny. Fortunately it is made of metal and feels great in...

Hi Everyone, I'm looking for help to eliminate 50HZ mains noise (Sydney, Australia) coming through my son's active monitors in his home studio. It has existed for a long time, including his hum-bucker guitars. Environment: Residential Property with 3 phase mains power Home studio comprising a...

You will always get some USB noise (it varies depending on the setup) if you use the unbalanced RCA output and the devices connected via USB do not have floating ground. Balanced Out and Headphones don't have this issue. You can also solve this by using galvanic isolation (SMSL PO100 to convert...

Just tried some FFTs now and saw the noise floor pumping with headphones out, weird. I’ll test different USB cables, although the one I used is from Topping and no issue with rear RCA. Still plenty of PS noise with rear balanced outputs. The review is expected to be a mix of very good and very...

I also have my doubts. An IFI Defender+ made no difference in this case. However, I also have a Schitt Modius, and while the whine is still there, it is much quieter which points toward the USB implementation. If it doesn't work, I can use it elsewhere, and it was only $99 on a Prime Day sale.

Just want to clarify - you get noise in measurements via USB connection? So it is a "ground-loop" related issue? Or the same with optical connection? For my use case, headamp + preamp for iLoad Micro Monitor with connection via RCA, this issue PS noise is not critical, but interesting to see the...

It's basically the same input. The USB-C will probably also have a small chip for negotiating the 20V power delivery otherwise the charger will probably default to 5V. How much of the common mode/leakage currents make it into the audio path depends on the PCB layout. The differential noise (the...

I'm going to test this one out as I've had cheaper DACs before outputting to the power amp and you can hear USB noise at some points through the speakers, given it has no balanced output only RCA, this issue would be more prominent without proper isolation. I recently had the SMSL AO300 Pro...

I hope the balanced connections solve your GPU noise issue. But I have my doubts that the RCA cables are what's picking up the GPU noise. More likely a poor USB implementation on the Motu. I have an unbalanced DAC that made terrible noise when connected directly to USB on my desktop computer...
