Measurements and conclusion
Contents
To give you some extra information, we took a few measurements. First, on the power supply of the PC. This is to give an idea of how hostile a PC’s environment is. In addition, we measured the Crystek clock of the SSD itself.
Power supply noise
We initially wanted to test the SSD in a separate PC. We measured that PC in terms of power supply noise as well as noise on the Ethernet side. You can see the results above: it’s not great. We see a lot of common-mode noise on the mains side as well as common-mode noise on the 12-volt line inside the PC itself. However, know that every PC suffers from common mode noise to a greater or lesser extent. It’s all about where you block it. Think of the USB port or Ethernet port. Anything you connect directly to the PC – or connect through the mains – can become contaminated.
Clock measurements
Fair is fair: the Crystek clock certainly does measure decent. On the lab power supply we see around 10 ps of jitter and -45dBc/Hz phase noise at 10 Hz offset (you can see what power supply and implementation does here. This should be -97dB according to Crystek).
A linear power supply does not make it directly better in this case. Now we must say that the Rigol lab power supply always gives very good results. Apparently a very clean power supply.
Great article. It’s a pity that the English comment regarding Revelation SSD and better RAM for audio is not shown here because I completely agree with the 1st comment: did you miss something?
There have been too many good results with the Revelation SSD + external power supply music files for at least 2 years to ignore. I would think that something else is going on with your set or with the (resolution) of the Alpha Audio computer if this does not improve anything audibly. (Or the mutec or your power supply or whatever?)
Since even longer ago it has been known, especially for DIY servers, that other RAM such as Apacer industrial wide temperature can also provide a huge improvement (if the Alpha Audio computer still uses standard RAM, definitely try this).
Julie OS could also be put on a smaller (eg 16 Gb) Optane M.2 memory for even better sound (if there is an M.2 slot left, definitely try!) Innuos used (only now) in the latest server SLC Apacer memory for the OS.
The music SSD fed with BV the JCAT Nano or an (even) better power supply should also give a better sound.
To make RAM sound even better, the power supply of the computer must also be of a higher level (the very best BV. Sean Jacobs). If the motherboard has 2 connections, definitely try with 12V 4pin and the ATX 24 pin with separate power supply. Also if the power supply is distributed, eg independent motherboard, SSD for OS and SSD for music, it also sounds better.
I’m certainly not saying here that you’re not doing well, so much and fast is being done in audio, but I recommend trying even more if you can’t hear a difference with this Revelation SSD or (Apacer) RAM.
There are simply too many users with very good results after upgrading memory (be it music SSD, RAM and OS memory). Also not even that expensive compared to other audio improvements. But as always not every system sounds the same and it can be more or less audible either ; YMMV.
I am very curious about results! Good luck!
Boy, are you late!
There IS Audiophile RAM on the market. For several years now. Apacer’s industrial grade RAM is touted as being superior to other types. I’m not smart enough to know how it’s supposed to work, but cruise over to Audiophile Style to get in on the conversation.
Neither am I smart enough to figure out if that powered SSD card works. I just know I almost went into cardiac arrest at the sight of the price.
Only God knows why we do what we do, and He’s apparently keeping it to Himself…because gods just wanna have fun. They just wanna. 🙂
Kan je navraag doen hoe de fabrikant deze SSD geïmplementeerd wil zien?
