USB C SPDIF Emitter

I bought this Cubilux USB-C to SPDIF transmitter to add an optical output to my devices, and it has worked exactly as I hoped. I use it to connect my iPhone to my Chord Mojo 2, and also my laptop to the Mojo 2, and in both cases the sound quality is very good – clean, detailed and noise-free. Setup is as simple as it gets: plug it into the USB-C port, connect an optical cable to the DAC, and it’s ready to go. No drivers or fiddling with settings were needed in my case. It locks onto the signal reliably and I haven’t had any dropouts or glitches. The build quality feels solid for such a small device, and it’s compact enough to throw in a bag for travel. For anyone who wants to add a proper digital optical output to a phone, tablet or laptop and feed a high-quality DAC like the Mojo 2, this is a very handy little adapter. I’m very pleased with it and happy to recommend it.

I got this to hook up my sonos ray as only input is optical, my MacBook is connected to Monitor via displaylink and adapter connected to monitor via usb, i then set MacBook sound output to usb in settings, also changed monitor sound output to usb, sound quality and connectivity all good, easy to install, good quality.

works completely as expected. Plug and play on both Windows 11 and Mac without any setup requirements. Sound quality is unaffected with no audible delay. It is abit pricey for what it is, but so far has done the job reliably

Very pleasantly surprised. I have only had it a couple of days so I cannot comment on its longevity but it does actually work. Its installed between a Mac Air M4 and a Yamaha 501 amp. It also works on my Teac DAC but as it has a single output rate only, its actually a better sound using the shortest path direct to the amps optical input. The sound lacks depth but that can be fiddled out to some extent and given my computer library is mostly old recordings that are not always CD quality that does not really matter. Stereo definition is also definitely there. All in all a great solution assuming it lasts and is well worth the £21 quid it cost. Problem is most buyers will, like me, be audiophiles and will expect it to be perfect which is not But is does solve the drop out issues that M series Mac users are experiencing with even the best DACS that don't have native usb c. And i.t also works perfectly well with the computer set to low power.

Age (mine) caused me to buy this. I listen to Amazon Music on my Hi-Fi via a Wiim Pro Plus streamer. I like the sound but although the controlling App for the Wiim is very good, it is not available on a PC. Using a tablet or phone, I have difficulty reading the screen and prefer to see the Amazon Music site online on the 60 inch TV in my living room. I needed a way of getting the sound from the USB outlet of the mini pc attached to the hi-fi into the optical input of the Wiim to take advantage of its AKG DAC. Should have been simply plug and play using the Cubilux and would have been had the said mini PC been attached to a screen. It isn't. The screen is attached to another mini PC connected to to the TV about 12 ft away. The answer was to control the pc attached to the hi-fi from the pc attached to the TV using Windows 'Remote Desktop'. Confusion on my part about which was the host and which was the receving PC led to 2 or 3 hours of changing and mixing settings before getting it right. The cubilux, completely oblivious and unperturbed by my confusion just worked. The sound is perfect and delivering the promised full 24 bit 192 khz to my hifi via an interface which is fully legible and straightforward. Summation, the Cubilux is simple, straightforward and effective. Me, not so much.

Worked for a couple of days and then stopped working. Checked on another DAC and different laptop, and it's definitely this device is faulty.

Fantastic little USB to SPDIF optic interface. I'm using it with a FOSI Audio DAC-04 Headphone amp, it's currently (the amp) unavailable but the identical looking AIYIMA DAC A2 is. I used to use the USB input for the audio signal but it was limited to 24bit 96kHz whereas the amp is capable of 24bit 192kHz when operating over optical. With the little Cubilux adapter I get the full 24bit/192kHz and sounds great with a pair of Bose headphones. Note you have to go into Sounds/advanced settings for your device to increase it from the default on Windows 10. I have attached some screenshots that show how to do this on Windows 10. Although I have a company laptop that runs Windows 11 I haven't tried it on there (our IT dept are very fussy about unapproved USB devices) but I suspect it will be very similar. I don't know about Chromebook or Apple sorry. I only use it for 2.0 stereo but I think it's great value for money as the sound from my amp is very good. Amazon music has plenty of high bit rate music to enjoy (I pay for my Amazon Prime).

I bought this as a way to get lossless audio from my iPad, iPhone and windows laptop to my HiFi and this works almost flawlessly. When steaming music the quality is amazing, no issues at all and audibly better quality than Bluetooth. YouTube and Netflix also work great, but when streaming video using the Apple TV app no audio comes through (using Windows and iPad apps). Luckily this isn't a dealbreaker for me (and also is likely Apple's fault rather than the manufacturer, since it works with other streaming services, hence I haven't docked any stars) but I would look for another product if playing back Apple TV content from a laptop or iPad will be important for you.
