SweetVinyl SugarCube SC-2 Mini Review


Remember when we used to record stuff? Put vinyl records on, make mixtapes on cassette, play them in the car, give them nervous­ly to prospective girlfriends with a carefully hand-writ- ten case insert, wondering if that track near the end isn’t a bit much for that stage of the relationship?

Where has it all gone? These days you’ll be lucky if your hi-fi amp even has a ‘record out’ around the back. It almost makes me chuckle when I review something which still has an input labelled ‘tape’.

It was compact discs which did for record­ing, of course, because once you could copy digitally and burn your own CDs (though heaven forbid I should suggest you so much as think of copying digital music in any way because we will get rude letters from lawyers forbidding any mention of such fun if do), the whole mixtape game was up. File sharing just made it even more quaint, while for our tastes sharing a Spotify playlist seems rather lacking in romance by comparison.

But now we are enjoying the revival of vinyl, and to a lesser and faintly ridiculous extent also of cassette, which must have tickled or perhaps utterly baffled the Dutch inventor of the compact cassette, Lou Ottens, before he died earlier this year, aged 94. So perhaps the time has come again for some recording fun. The makers of the Sugarcube clearly think so. Not only will they help you record your vinyl, they’ll even make it sound better in the process. (And thankfully, no cassettes are involved.)


The Sugarcube range hails from SweetVinyl in Mountain View, California, which funds product development via the Indiegogo plat­form, most recently with the SC-2 models updating a legacy range. There are other variants, including the SC-2 Mini/I’hono, which adds a phono stage to the model reviewed here, but Australian distributor Decibel Hi-Fi says availability for that one is currently ‘constrained’. So the only key prerequisite for this SC-2 Mini is that you’ll require a phono stage, either standalone prior to the SC-2 Mini’s inputs, or within an amplifier which offers a tape loop.

Around the back of the SC-2 Mini in ad­dition to its inputs are analogue outputs for connection to your playback system or tape loop, USB slots allowing an external DAC to be used, a USB slot for the provided Wi-Fi adaptor, and an Ethernet socket if you’re able to present the unit with a hard-wired network connection.

On the front is another USB slot to which storage can be attached to transfer record­ings, along with a knob and buttons to control how much cleaning-up the SC-2 will do to your recordings.

It’s a solid little unit; I couldn’t criticise the engineering-like construction other than at its feet, where sorbothane-like rings in a bottom groove no doubt provide useful isolation against vibration, but had a ten­dency to fall out whenever I moved it. With my turntable and preamp connected to the Sugarcube’s input, I powered up the unit.


The front panel display is a bit alarming at first. A couple of company ident screens flash up very quickly, then there’s nothing but ‘snow’. This won’t alarm those who have fully perused the manual in advance, as did I, of course, being a responsible reviewer, though in this case the required information appears only in the digital manual supplied on a stick, and not in the fold-out ‘welcome’ sheet. In there, on page 12 of 54, it tells you not to be alarmed by the snow on the display: “When you power up your SugarCube, it will take about two minutes to complete its startup procedures. During this time, the LCD display will show snow (our hu­morous tip of the hat to the old days of analog TV). There is nothing wrong with your unit. We apologize for the wait but we have some seriously sophisticated software loading and it simply takes additional time. When you hear the results of our efforts, you will agree that it was worth the wait.”

I don’t encounter many jokes in product manuals, let alone baked into the software, so kudos for that, and I braced myself for any further amusement at my expense further down the line. In fact it can’t have taken longer than 30 seconds before the snow was replaced by a far more reassuring screen with the SugarCube logo, and I was able to progress to networking and using the app.

I had given the SugarCube unit an Ether­net cable connection, thereby avoiding use of the supplied Wi-Fi dongle. But the app didn’t automatically ‘see’ the unit on my network, as the manual suggested it would when using Ethernet. It offered the options of Wi-Fi set-up, which I didn’t want, or ‘Enter IP address’. The unit usefully shows its IP address if you hold down the ‘Bypass’ button. I entered it into the app. Success!

Just to be thorough, I removed the Eth­ernet cable and inserted the Wi-Fi dongle to try set-up that way. Wi-Fi set-up involves pressing the big front button for more than seven seconds (say the app’s instructions) or five seconds (says the manual) then letting go, until after a worrying pause the screen displays ‘Wi-Fi Set-up’. You can then con­nect your device, in my case a current iPad Pro, to the SugarCube’s own Wi-Fi network, then return to the app. Whereupon, says the manual, the SugarCube will be found. Oddly the iPad Pro failed, but a 2016 iPhone SE worked, though the tiny screen didn’t do the app any favours.

There is one more way to control the SweetVinyl SugarCube, which is via a Chrome browser. I unplugged the Wi-Fi don­gle and returned the SugarCube to Ethernet. Then, as described in the manual, I typed in the IP address followed by :5123 (its port number) for external control. Instant success here, and the first thing that I did, under the ‘Support’ menu, was to accept a software update. And I’m glad I ended up with this method of control, because the bigger the screen, the clearer were the editing functions once 1 started recording.


I began by pressing the unit’s ‘Bypass’ but­ton to check that the sound of my vinyl was flowing freely. Then on the app I went to the ‘Recording’ section; dropped the needle and pressed ‘New recording’. A light on the unit flashed red, and the app indicated things were under way. Well, that could hardly be easier.

The app immediately offered to search for the album’s metadata if I cared to enter the artist or catalogue number. It managed no match for Alex The Astronaut, but this was not unexpected, as 1 was playing a non-mainstream piece of vinyl — a disc combining her first two digital EPs on one LP. But I found the catalogue number on the back of the album, which was ATA003, and was quite astonished to find that the app immediately returned the correct artwork and album details (see overleaf). It even popped the artwork up on the front-panel display. Then I sat back to enjoy the album.

The Sugarcube SC-2 Mini is a great recorder, helpful at splitting tracks and I Ding LP metadata. But vinyl fans may well find they ove it even more for day-to-day playback

If you’re more keen to wander off and leave it running, you can limit the recording length (e.g. to 20 minutes), which is a nice user-friendly touch.

As noted, the app was fairly cramped for operation on a smallish phone, but big, bold and easy to handle on the Chrome browser — noting also that the Sugarcube seemed happy for me to use both control systems at the same time. If not particularly swish in terms of font use and design, it’s perfectly clear what you need to do.

I had already, via the web interface, set recording quality to 24-bit/l92k FLAG, and this particular LP being fresh and new, I had the cleaning circuit set to ‘4 Low’.

I stopped the recording at the end, and investigated how I might break the album into individual tracks. You don’t have to do this — you may be happy with com­plete sides of digitised vinyl, but once I got the hang of the track splitting, I found the process to be quick and accurate, sliding start and stop markers around to the re­quired positions (see image overleaf), with a subsequent ‘trim tracks’ option allowing finer adjustments. This is best done by lis­tening as you move the markers — though the audio comes from your browser or tablet, not out of the SC-2. If you face any confusion, there’s a full recording guide on a USB stick which comes in the box — it might be useful if SweetVinyl would put these guides online, so that you can find them if you mislay the stick, as well as benefit from any revisions.

Once recorded and split, you can export the files to a USB stick or drive plugged into the front of the unit. It took about three minutes to transfer my five split songs, and there they were, not only neatly foldcred by artist and album, but with the artwork in the folder too, and the full unbroken album side too (you can prevent this last bonus by using the ‘Side Format’ options). I am not sure how much internal storage resides inside the Sugarcube itself, but clearly exporting is the method to be used; it’s not designed to be used as a hard-drive music server; indeed there’s no apparent way to play back recordings out of the Sugarcube’s own sockets.

As I became accustomed to its ways I real­ised the best way to start a recording is just to punch the Record button on the front panel as soon as the stylus drops.

I also switched from FLAG to the more Mac-Friendly WAV or Apple Lossless, and tried the option to save recordings direct to the controlling device rather than to USB.

The Sugarcube SC-2 Mini is a new type of hi-fi component you’ve never realised you needed!

This allowed me to drop the files straight into my Mac’s download folder as a zip file, which is neater, though the network transfer was far slower than via USB, despite the SC- 2’s gigabit Ethernet.

I was soon recording records almost as fast as 1 could change LPs, the only delay being the few minutes after recording that the unit takes to generate the audio preview required for editing. Use that time to put the LP away and make your next selection, then you can be recording the next side as you edit the previous one. Warning — this is highly addictive!

There are some obvious questions here. Do you need a unit costing nearly $4,000 to record your vinyl? You could use any computer with a simple audio interface and free software such as Audacity. Click and pop removal can be done with fairly cheap software like ClickRepair, which operates effectively up to 96kHz. Why pay more?

I can see several good reasons. Firstly, a simple audio interface will have a basic ana- logue-to-digital converter in it, whereas Sug- arcube’s ADC (from ARM) is of such quality that I couldn’t easily pick processed sound from the sound with ‘bypass’ selected, even with click removal up high.

Second, the Sugarcube can sit permanent­ly looped into your system, on bypass when not in use, immediately available to start recording whenever you feel the whim.


And thirdly 1 was mightily impressed by the ability of the Sugarcube not only to make its recordings of click-reduced vinyl, but to undertake this process in real-time, whether you’re recording or not. This makes the unit useful even if you never want to record anything, though I suppose the live vinyl cleaning does come with the caveat that you are listening through a system that digitises the input (though that is now happening with the phono inputs of many smart amplifiers anyway, e.g. Linn, NAD’s M33 etc.).

Real-time click removal is quite the thing. I have a pretty clean copy of The

Alan Parsons Project’s ‘Eye in the Sky’ which nevertheless has a loud crack in the left channel at the fade of track one. I repeated this section with a ‘4 (Low)’ level of repair in circuit — the click entirely van­ished. Using the web interface I could A-B quickly from bypassed sound to repaired sound, and again besides the slight delay in processing, I couldn’t pick a difference. Per­haps the smallest smidgeon of upper-eche­lon openness was curtailed, I thought, but then I tried just banging the button and try­ing to pick blind which was bypassed and which processed and couldn’t do so reliably. So vinyl cleaned, instantly! 1 can see some vinyl-lovers thinking it’s worth four grand for that alone.

There’s an interesting option to listen not to the cleaned vinyl, but only to what has been removed — just the clicks. This makes it very clear the work that’s being done by the SC-2 (see 4 and 5 above).

Not that any of this means you shouldn’t clean your vinyl properly — and Decibel Hi-Fi is the distributor of several excellent LP cleaning machines and kits. But I was

constantly impressed by the Sugarcube. One torture test to which 1 subjected the SweetVinyl Sugarcube SC-2 was a dreadfully damaged copy of Simon & Garfunkel’s ‘Con­cert in Central Park’, where the opening groove and fade is laden with all manner of noise. Here Level ‘4 (Low)’ wasn’t enough — a full-on scratch still cracked through on every revolution. But up on ’10 (Max)’, even the sound of this severe scratch was reduced to a barely audible bump, and I could enjoy the sound of near-silence.


The Sugarcube SC-2 Mini is a great recorder of vinyl, very helpful at splitting tracks and excellent at ID-ing LPs. But vinyl fans may well love it even more for day-to-day playback. You can leave it on bypass with new and clean pressings, or easily dial up a preferred level of click removal for any­thing that’s in less than pristine condition. In this mode SweetVinyl’s Sugarcube SC-2 Mini is a new type of hi-fi component you have never realised you needed.

Until now! – Jez Ford
