I now own an SSL

Post by SafeandSound Mastering »

well, an SSL2+ MK II audio interface. :thumbup: Treated myself today. I have been on the hunt for a new interface and the MIDI I/O swung it for me, though I suspect you can get a cheap USB midi i/o without any problem. Many I appreciated wanted to see the optical I/O like some of larger Audients.

I have a couple of Audients here actually (as back up units only) An ID24 and and ID4. One for if my converters croak and go for repair (Crane Song and Mytek) and one if my headphone amp croaks.

I want to keep them as back up redundancy so gave SSL a shot, spread the money between some other market players. Not too concerned about ultra low latency performance for my hobby machine. I have plenty of options available to me but it is reasonably likely that the SSL will end up of whatever becomes the new hobby music machine (likely a 20 core i7 machine). I really love how the SSL2+ MK II looks, chunky and really SSL-ey. Not up for £600.00 of RME again this time round.

I may regret that if the drivers are not quite as good but as it is hobby machine only and used on a very well specced SCAN machine it should work out ok. I am sure 1,000's of people manage without RME. Always RME on the pro machines here though.

I shall look forwards to installing it.

Up at 6:30am today to wire this up and do very basic tests. All working fine and sounding nice.

No DAW on this PC as yet, it's a "floating PC" awaiting whatever I see fit, redundancy for main studio or a new machine for music making it'll do either easily.

Driver loaded fine, audio from headphones sounded good, mic inputs sound quiet and clean, 4K button does not cause any audio click in headphones when pressed. Headphone output plenty loud for me (250 Ohm DT-990 Pro tested)

Audio sounds nice in headphones, detailed enough, plenty of lows, good all through the spectrum.

Of course I cannot really test much in the way of ASIO performance but I am already impressed for the price point especially including 32Bit / 192kHz DAC chip.

It looks very nice to the eye and I was interested to see SSL are using 75pct recycled plastic and 80pct recycled aluminium in this device.

So far I am very pleased with it.

I just did some basic playback tests with a project that I progressively increased the ASIO loading. Ramping up oversampling on some plug ins to 32 x and so on. Broadly on playback it is on par with the RME Digiface, reading the same on the Cubase ASIO metering for any given project.

Intel i9-12900 Machine

Obviously 2 different device types, one with purely optical I/O (and headphones) And the SSL2+ MK II being 2 in 4 out A/D - D/As and tested on 1 specific PC and DAW (Cubase)

The Windows CPU graphs also seemed about the same, drop out free playback was noted. I set both interfaces at anywhere between 1024 and 32 samples the SSL includes 16 samples. The latency times reported in Cubase were longer for the SSL driver at any given sample setting.

Examples :

RME In 21.396 O 22.438 @ 1024 samples
SSL In 22.833 O 26.500 @ 1024 samples

RME In 1.396 O 2.438 64 samples
SSL In 2.167 O 3.500 @ 64 samples

Clearly there is a difference but very much satisfactory. No ultimate conclusions drawn but it holds its own in the test this evening.

But what does it sound like?
I'm thinking of buying one of those SSL 18’s, so definitely interested in your opinions on the sound.
As for RME, software is supposed to be good, but it's complicated , they are over priced for what they are.

It sounds good as I mentioned earlier (cans only). I did not want to go into too much detail on the DAC L/R side as I have only listened a relatively short time. It is not easy to judge by merely switching drivers, as the gap is by far too long for the ear to retain fine sonic signatures. You need near to instantaneous switching. And using just 1 test track is not really complete.

What I am reasonably sure of after many switches across a looped passage with relevant sonic info, although relatively slowly is that the Crane Song Solaris Quantum DAC is superior from what I hear here (in this system/room, which is pretty ace I have to say.) and for what I am doing for work.

Crane Song soundstage overall is clearer, deeper (not really wider though) and easier to hear more precisely where sounds originate L to R (especially transients, percussion hats, sparkly details), transients stronger (can be described as punchy details) but also through the spectrum, a little less harsh up in the upper mids yet still detailed. Bass is not dissimilar as far as I recall though I will have a more close bass listening session as you can only really focus on a restricted range of audible factors at any one time.

Given the price difference not entirely surprising. Not that price is everything all the time, there are bargians to be had.

For the money it is very good and I am going to be very happy making my music on th SSL when the time comes. (current device for making music is an almost antique PCI RME 9632)

I think these 32 bit / 192kHz converters (which Crane Song uses also) are at a stage where for recording and mixing there is zero impediment to audio work, be it Audient/SSL/RME and pretty much any others (though I personally never found RME sounded superb, just good, but we buy it for drivers, hardware reliability and long term support which counts for much.)

Good 24/96 or 24/192 audo interfaces were never a barrier either but as I have said before in 2025 when it comes to results the biggest issue will be your abilty, your room and monitors. And I happen to consider all 3 are completely interdependent on each other (which can also inform tools choices)

As an example there is one software mastering EQ which makes things slightly smaller sounding when flat and engaged, this is repeatable, over and over again with ease, I hear this stuff quite easily. (Yet plug in doctor suggests nothing of concer or that should be audible, yet it absolutely repeatably is.) Once in a blue moon, smaller is what you might need to optimize something + unique curves = unique value over many years.

Anything is valid in optimizing audio at the final stage. I discount nothing.

Apologies to go self referencial but all listening is. That is why it is called listening not measuring. :thumbup:

For myself details do matter considerably.

I guess different people have different preferences, but I couldn't agree less! :headbang:

The Matrix view for routing is about as simple as it could possibly be — inputs on one axis, outputs on the other, click to create/break the routing.

The three-mixer view for interface inputs, software (DAW) outputs and interface outputs could only be simpler if they reverted to the older version of Totalmix, when none of the interfaces had DSP effects on board... but you can hide all that stuff if you don't want to use it.

Thirded.

I accept that it can confuse newcomers, but a few minutes with the manual proves it to be logical, simple, and supremely powerful. All it takes is a little time and effort.

As I've said many times, I never want to work without TotalMix if I can help it.

I should think that RMe would be a good choice, if you needed to change set-up's and routing like in a commercial context, but I never change anything, apart from direct and software monitoring. It would be wasted on me, all I want is a set and forget device with a nice sound.

Re: I now own an SSL

You will get a nice sound with the SSL and Audient Arpangel. They are on par with each other as far as a basic listening test went, similar.

The top end on these 2 are not as jaw droppingly detailed as the Crane Song Solaris. And after listening more closely the Solaris does seem to have a slightly more spacious stereo image and percussive transients far more lively, it presents more information to the ears.

No question I could pick the Crane Song out, so much for DACs all sounding the same ! I can hear the result of dynamic processing better on the Crane Song, that is really worthwhile. (and this is why I believe skill in listening potentially informs equipment selection and can inform tool EQ/Comp/ limiters (I have 8 limiters, most of the main ones.) and set up and choices.

There is less difference in the bottom end between the SSL/Audient and Crane Song. I would say I would probably have difficulty hearing the difference between the SSL and Audient ID24 DAC. That would be a struggle, similar classes of DAC are rather similar.

Interestingly my findings are that this is an area (bass) of the spectrum where the latest 32 bit DAC chips in budget/mid price interfaces seem to have narrowed differences. Not that there is less bass but it sounds tighter and better defined. (I always found the Benchmark DAC-1 HDR for example rather thick sounding down there. I do not miss it in this system.) It was a bit much when you have ample bottom end in your monitoring PMC IB1S are not short on clean, fat, deep bottom so these later DACs work well in this system.

It has concluded what I already thought/felt/heard, the Solaris is a perfect DAC for what I am using it for, mastering. I have simply never heard this much information from a DAC and more information if you can deal with it is better for that task.

What is lovely (and a benefit I was not expecting) is now I can have a DAC (not sure which one yet, SSL or Audient, both absolutely good.) attached and wired to the mastering PC akin to something people will be using in project/home studios to switch to. Rather like my Dynaudio BM6P on a switch. So I will have a project studio grade DAC to audition with as well.

It might be useful to check on one of these if I have been doing work on sides or stereo image. I do more in the mid channel generally, sides only when needed and that is less than the mid channel. I will see if it integrates into my work. I have managed without till now but sometimes adding something new and slowly testing it can be of use.

Technically the Audient DAC is quieter (Possibly even quieter on paper than the Crane Song) insignficant in the real world listening, all of these DACs are to all intents and purposes totally silent in operation.

I did look into one of the end user tests on Audio Science Review forum with interest for both the ADC and DAC side, it's a decent site to look at graphs and measurements.

I'm listener at heart but do enjoy some technical test data as much as anyone. :thumbup:

It is remarkable how converter technology continues to improve incrementally over the years, despite the already near-perfect level achieved by even the budget stuff.

The Benchmark DAC-1 noticeably raised the standards of D-A conversion 20 years ago, by introducing the concept of separating the source and DAC clocks to reduce decoder jitter to new low levels. Something that has proved of critical importance.

Lots of other manufacturers embraced that same idea — including Crane Song — and Benchmark themselves also further refined the tech through their DAC-2 and DAC-3, of course.

The interesting thing is all of these devices measure close to flat (Audient's seem to droop a tad up at the extreme top ADC side), have inaudible noise, broadly inconsequential jitter but certainly there are audible differences in some cases, not all.

I started out with the Benchmark DAC-1 HDR (has LM4562 opamps or the equivalents which I have enjoyed the sound of.)

That is a DAC which I think people who like a rich low end would enjoy.

Sure there are other modern DACs, no shortages in that dept.

Re: I now own an SSL

Listening to the .wav file of this track, loudly mastered, ultra precise modern sound but retains macro dynamics, it has a very thick low end on it but lots of movement in the stereo image. A very appropriate track for the day being mid summer. It is a very good modern reference track, lots going on.

https://djtristan.bandcamp.com/track/summer-solstice

On the Crane Song Solaris it is exploding out of the speakers, punch, transients, super interesting stereo image. SSL/Audient does not match that, they are good but it misses the ultimate excitement that the track can produce.

I do not think it is an understatement to say the Audient and SSL could influence me to make brighter masters and probably affect what I did with dynamics processing as well, you might not hear what happens to transients as well with compression pushing things down or the other way if enhancing transients intentionally.

It is not fair to compare what is arguably one of the bests DAC's on the planet. These audio interfaces are seriously good for their price point. But to those who think there is no differences, there absolutely is, unquestionable and in this room I could confidently pick the Crane Song out over and again.

Probably with a 2 mins gap between the listening I could still pick it out, that's how big the differences are. Probably small for some but not what I am hearing. When you seperate each of the sonic qualities out and listen, top end, transients, dynamic transient positioning in the image, overall image positioning and depth. They all combine to just make the listening more informed.

All I can say is the Crane Song is worth every penny I paid for it in context of its use.

The SSL and Audient are fantasic value at their price points and I would have zero qualms about making music on them, even professionally. :thumbup:

Re: I now own an SSL

Post by SafeandSound Mastering »

Having an ear rest here so wanted to add a few tidbits of extra information discovered over the weekend. The above reported output latencies roughly halve at most buffer/sample settings when the "Safe mode" is unchecked in the SSL driver applet. Performance not really tested but thought it worth mentioning.

At gain levels that would never be used in any real world scenario (extremely high) I noticed a very slight but audible "modem" kind of data noise coming from outputs 1 and 2.

I suspected some interference coming down the USB C connecting cable so did 8 turns on a large ferrite ring. The data sound vanished, even though it would never have been a problem anyway.

I am very impressed with this little interface, it has multiple uses here and I can attach to any machine I want as a headphone amp, hobby music machine interface (all importantly with MIDI I/O) or a secondary "home studio check DAC" if I want to. It is proving very versatile, I love it !

I am sure the Audient's are every bit as good, for now I have just been mainly testing the SSL2+ MK II

I would almost certainly buy the Crane Song again though should it irrepairably break, it's that good.
