SOtM smS-200 unveiled at Munich Hi-End

Recommended Posts

As per comments above seems to hang around 30% for some time time then fairly quickly completes. The kernel check and install also seems to take forever likewise the reboots in order to complete installation but very happy with sound. I would recommend whenever you do an update check your settings for whichever player you use eg MPD which I use as I find that it always changes one of the settings.

I asked May Park when the Kernel update should be done. Turns out it doesn't matter:

 

"Thanks for your request, actually it doesn’t matter when it has to be done, the kernel update is about to update the capable DAC information for the native dsd playback."
Best regards, May

.... “kernel” is then a little bit misleading ..... good to know, thank you!

Many thanks for asking and giving this feedback on May's answer.

 

At least, we can count on one of the few audiophile certainty : it actually does not matter ! 😎

Hi guys,

May I know what PSU everyone is using to power their units? I’m using sps-500 with nice results. I even tried a sps-1000 but preferred the sps-500. Ppl keep telling me to get a LPS but I feel the sps-500 suits better, am I the minority here?

When I installed 4.7 firmware, I could not have sMS200 reboot.  I waited for 1 hr.  Since then, through 4.8 and 4.9 upgrade, I never could reboot the sMS 200.  I have to power-off my MacBook.  Upgrades appeared work just fine though.

 

anyone can reports how long for rebooting the sMS 200 at the end of installation?

If you need tu burn a new card there is non 4.90 download available, afaik, but from here (chapter 1.3)

https://www.docs.sotm-audio.com/doku.php?id=en:eunhasu:burn_sdcard_image

you can download the 4.70 version then you can update to 4.90

 

@Mahler and Bach on Computer if you are still facing too long reboot it could be better to burn a new microsd card.

I'm using the SPS-500. Sounds good, but then I haven't tried anything else. I bought mine with the 500 PS.

The SPS 500 is an excellent PSU. And an normal LPS isn,t always the better one. Some sounds very bolt and brainless..Though the Farad3 LPS is an improvement on the SmS200ultra. You have to order the right voltage 9 or 12v .

Hi Tom,

I so totally agree with you regarding the sps-500 being an excellent PSU. I too agree that when I plugged the sps-1000 into the sms-200 after I had tried it with tx-usb ultra, there was a slight difference to the presentation. The thing I didn't like with the sps-1000 though, I lost dynamism and attack speed/transient speed. (I'm not good with audiophile mambo jambo, LOL), with the sps-500 back in, things were much faster. I must admit one thing though, with sps-500, the quality and the charater of the PC really helps with the tone of the sound, meaning for a cooler sound, get a cooler PC. It reacts as do most soTm gear I have noticed. 

 

The sps-500 though can sound a bit digital sounding if the power cord is of a lesser quality, but otherwise, I love it too and am so glad I have company too.

I have had the opportunity to try the SPS-500 power supply with my SMS-200 Ultra Neo.  Unfortunately it did not sound as good as the Studer-900 LPS I am using or a number of other LPS's I have tried with my unit.  The SPS-500 always sounded a bit lean compared to the LPS's.

Hi Clothears,

May I know what PC u are using with the Studer-900? In all honesty, I don’t really hear the leaness but I find LPS not being fast enough for my taste. Maybe it’s just me I Guess. Thank you for the input though, I might as well get a Studer to try. Any recommendations?

I'm using the SPS-500 it works perfectly well for both my sms-200 and my tX-USBhub with a Y DC cable from ghent audio

I'm also using a Furutech AC cable to power the SPS-500

Regarding PSU, I've tried out several LPS options (although none of the options mentioned in this thread 😆). Most of them gave a somewhat relaxed presentation with lots of details but with loss of dynamics opposed to my current favorite: A no-name LPS with a fan (that can be stoped with a paper clips 🙃). This gives the right level of attack and rhythm to the music and makes the sms-200 less soft.

 

Realizing that this was not my final solution, I've finally settled on a Paul Hynes SR4 LPS (after reading much about it). I'm very curious whether it will give the balance between attack and musicality to fit my system. So fingers crossed - its a bit delayed due to the corona pandemic.

My feelings exactly bro, loss of Attack and dynamics is what I hear using a LPS. Please keep us posted on the PH please. I’m told the Farad3 is also good. Plixir Elite is another, but as said I love the Attack,speed and dynamics of the sps. It’s quiet too, well at least to my ears.

The LPS sound you're describing is probably due to high output impedance.

The lower the output impedance the better the sound, especially in the areas of speed and dynamics.

The Farad3, which I have, is very good, but only slightly better overall than the sps-500.

Most other LPS's I've tried did not give a clear improvement over the sps-500 and some had drawbacks too, like the ones you've described.

I'd love to try the new PHD, but I'm a bit apprehensive, due to delays and such.

I've had my fair share of delivery horror stories to stomach yet another...

The Plixir Elite is also a viable candidate, but I've yet to try it...

I upgraded the firmware from 4.56 from my old SDcard all the way to 4.9.  It reboot every time with a step forward.  I am trying HQPlayer.  Before correcting this rebooting problem.  I could not do upsampling PCM file to DSD.  After that, the upsampling works.  Thank you very much!

I don't use a PC at all.  I run the SMS-200 Ultra Neo as a stand alone using MPD with a USB attached 3Tb hard drive in a caddy to hold my library.  I control it using an app called "Soundirok".  I'm a firm believer in keeping it simple.

 

Here is a picture of my dual 12V DIY LPS based on the Studer 900 board (pimped with Mundorf caps).

On my system, there is no way I would choose the SPS-500 over my DIY LPS.

Hi Clothears,

My apologies for not being clear, by PC I meant Power Cord. I'm personally using Tellurium Silver cables. Nice work with the LPS bro. Thank you for all the inputs, its much appreciated.

Dear Tedwoods, you couldn't have put it into a cup.  The SotM SpS500 is an excellent power supply and does many LPS power supplies such as Teddy Pardo, Keces HDplex and SBooster in dust bites on SotM equipment.  The Farad3 was the first to make a real difference.  More dynamic in the image, Tighter low and especially the top high is phenomenal.  Incidentally, it is important to use a good fuse and at least level2 connection cable.  Last but not least, it is important to place the power supply as close to the unit as possible to keep the cable as short as possible ...Though as said before it isn,t like night and day. If you have the Sps500 stick to it.

Thank you Tom for clearing the air. On another note, I'm currently using Neotech 18awg solid silver DC cables, I am thinking of getting the Mundorf Silver/Gold 15awg to give it a shot.

Hi Ted,

Thank you so much for this. It was very re-assuring. My only wish is that I had posted this question here earlier so that I would not have lost so many sleepless nights. LOL. Really appreciate your comparsion with the Farad 3 as I have always wondered, just how much better can it get, cause as I have said, I think the sps-500 is already operating at a very high level, well at least for me. Once again Thank you.
