Kingrex advise manual driver installation before connection to a computer to prevent Windows automatically installing an unsuitable driver. Kingrex recommend Windows 7 and Mac OS-X 10.6 (Snow Leopard) or later, but older OSes will work, including XP. After hours of searching and using all the models on the market, we have found the best USB To SPDIF Converter Audiophile for 2023. See our ranking below! Our review of five USB-to-S/PDIF convertors invokes digital religion, Noel Keywood says. Rafael Todes listens in supplication. The figure also shows a key feature of this unit, indeed the only feature I wanted, USB streaming conversion to SPDIF. Those are output, not inputs. The D10 takes a USB input and provides a SPDIF output (coax and optical) so any product with a DAC in it becomes a USB streaming DAC. Words are one thing, data is another. So let's see measure the performance of S/PDIF and DAC on the same USB and see how they differ. Alas, USB seems to have taken the market by the storm and increasingly DACs have only USB input. I had to dig deep in my stash of DACs to find the ones that still have S/PDIF input. Here is their performance on the venerable J-Test signal at 48 Khz/24-bit.
The 'dirty' and 'clean' sides are both isolated by a chip. The lettering on the chip was removed, but I’m pretty sure this is the ADuM* chip, isolating the I2S lines between the XMOS chip and the SPDIF output. Another convertor with a wall wart power supply! This one has an LED display with a volume control. My general impression in the Mozart Prague Symphony recording was that it was finding the elegance in the recording that left most of the others standing. It was the most believable of the convertors that I heard, with the possible exception of the Halide Bridge, which shared some of its characteristics. The sound of the strings was large, solid and timbrally refined. When I listened to the 'Dance of the Tumblers' on the Weiss DAC202’s FireWire output against it, the Audiophilleo managed to separate the texture of the cellos and basses better, where FireWire merged the two sections to a greater extent. The soundstage of the Audiophilleo was a few yards (metres!) deeper. The unit is not USB powered like many, so a USB power supply upgrade will not help. It has its own small wall wart supply, delivering 7.5V at 200mA. A battery version is available however. On the computer side, I was using my hi-man PC server (equipped with powerful i5 processor, fast RAM, SSD, Seasonic fanless PSU, various SOtM bits including PCI/USB SOtM card), running Win 7/64, JRMC 17 and JPlay v4.1. Let’s start with the engineering part first. I haven’t seen another USB/SPDIF converter, designed with this level of attention to details.

There was also much better layering of instruments, and air around the outlines. The instruments sounded not only better separated in space, but also much more 3-dimensional.
We have more than one piece of paper here. The European safety CE mark shows conformity with health, safety, and environmental protection standards for products sold within the European Economic Area. Two CE conformance documents in the figure apply to different standards but the photo is too fuzzy to see which document is certifying what standard. The -20dB attenuator and change in sampling rate moves the noise floor up. The accurate noise floor levels, with FFT processing gain, are shown in the first three spectra in the measurement sections with the QA401 analyzer at 48k samples/sec. I did not need the attenuator with the signal level at -50mVRMS or less. What factors deserve consideration when shopping for an effective USB To SPDIF Converter Audiophile? So – how do you know if your DAC will benefit from a USB-S/PDIF converter or not? First up: ‘asynchronous USB’ gets touted by marketing departments as a fix-all solution. It isn’t. I’ve heard numerous DACs that use an async USB implementation but slap an Audiophilleo or Concero on them and presto (!), an altogether more vivid and propulsive presentation. We need to dig deeper into what the manufacturer has done with USB to find clues as to how good it might sound. An XMOS chipset is no magic bullet either. Ditto galvanic isolation. They all help, yes, but they still might not surpass the tonal colour and bass energy that you hear from many an off-board box.With Foobar, all the distortion and noise issues I was seeing with Groove Music went away. Every spectrum I show below had to be replaced flushing 20 hours of work with the image preparation (I did not sign up to do graphics, the print magazines had staff, but this is what web publishing is like). Next time I will listen to Carlo when he tells me something. Foobar is still a little flakey. It will mute at times if the computer is busy doing other things. It can mysteriously open a window when you’re looking to confirm a setting. It also completely froze once requiring a system restart. A: SPDIF can take many forms: Digital Coax, AES/XLR, optical, i2s, and BNC seem to be the most popular. All high-quality DACS will have one or more of these ports in addition to the USB input. Q: What is the best power supply for audio converters? After a cursory survey of the different adapters concerned, I was immediately drawn to this unusual audio piece. It is literally a cable, with the electronics built into the cable – the S/PDIF end. It takes it’s power from the USB on the laptop, but can be cleverly upgraded by providing dedicated power. The other is the Berkeley. Sorry couldn't rank it as high as you did - very good - but only third on my list behind the Wavelength and Off-Ramp (OR) although it was so close to the Wavelength you could reasonably call it a tie. That said though I have been told with direct mode in Audirvana the Berkeley pulls ahead and even the AP2 is excruciatingly close to the OR.
