NVMe SSD designed for audiophiles


Recommended Posts

Yes I got confused yesterday when I typed earlier response. I still have the Audiolinux on a USB / ramroot and all for my endpoint fanless minipc. Didnt like it at all. I can hear why others like the clarity and the dynamic SQ but to my ears it is not to my liking. Still prefer the Windows Server SQ. 

Trying out Euphony now. Strange that it sounds 'not good' = checking my settings and trying basic 44.1 khz CD Wave files to check. Hires 705.6 sounded "not good".

I too have a Euphony license but I find Windows to be more musical and involving. Euphony sounds euphonic but muffled (low fidelity) and very hard to understand music lyrics. It seems to me that notes are truncated (decays are shorter). The music is so vidid and intonation and singer inflection is easily rendered with Window. I use the same hardware (swapping same capacity Optane drive to do the comparison.)

In response to your observations about Windows OS =

Win 10 Pro, Win LTSC, Windows Server 2012, 2016, 2019 then GUI and Core

With AO2 and AO3. Fidelizer 6.0 to 8.0

 

Let me summarize my impressions and opinions.

Windows 10 Pro is Noisy, cluttered. - Obviously because of too many processes running, and the electrical noise generated. - even with programs like AO and Fidelizer, you will need to have Project Lasso/ MinorityClean(? is that the name) to reduce and prioritize the processes.

 

Windows LTSC - a step in the right direction but still sounds bland - But it is a lot quieter and less cluttered sounding than 10 Pro - 10 Pro is unlistenable on a good transparent system

 

Let me bring in JRiver MC 23 -26 (I am on 26 now) = PLaying from RAM mode the entire song brings a great improvement to the sound. Listenable - all other Modes - Yuks! Only good for casual background music playback.

 

Audiolinux - good for End point. But it gave a high frequency tilt to the sound = Not using it any longer

 

Euphony - on trial mode now.

My OS for the Main Rig >>>

What I prefer are the Server OS's of Windows - 2012 was OK, 2016 was quite a bit improved.

But 2019 Win Server OS even in GUI mode Without Fidelizer and AO is quite pleasant to listen to. 

It is quiet, neutral in the bass/mids/highs - No nasties and like you quoted above, intonation and pronunication by vocalist are clearly heard.

 

It is when you switch to CORE with AO3 / Fidelizer 8.0 Pro that you get the processes down to 20 in the most extreme case- No internet, No remote network in, no WIndows Defender... almost everything is switched off. 

 

The issue is that it is SO transparent that you run into expose' of the weakness of the music playback chain.

On USB - the digital sound of your bad PC power, USB hub noise, Ground Voltage different levels, all are heard exactly for what they are. 

These have to be sorted out.

 

Using ethernet /switches/Clocks - I have gone 2 switches and Ether-regen in series with 2 clocks 50ohm/75 ohm and SOTM Ultra Neo - Cleans up the noise but the Vividness and Clean Vitality and Dynamism of the Sound is scrubbed and filtered by all those transformers in the chain of switches.

 

I have since switched back to USB direct connection to my DAC using many tricks including a double headed LH Labs USB cable which allows the injection of Uptone Regen's LPS1.2 power into the Isoregen separate from the data link. This already comes from a Clones Audio SHAAR USB PCIE card. LT3045 and Supercharged battery packs power everything of 5V and 12V. No SMPs at all in my system. Internet Broadband banished entirely from my music room. Music Server is cut off from all outside electrical/network interference

 

The components I use are not up to the JCAT Femto, Taiko Extreme, Paul Hynes level but I find that synergy and matching and extreme care in balancing the Power/Isolation/Filtering arrangements on my playback system is giving me a sound that I can enjoy music on.

 

Back to the FEMTO M.2 card testing topic

Just continued to test the card with further burn in. The SQ is stabilizing at a very high level. It is a very good neutral sounding drive ( Ha! NVME drives have SQ characteristics - who would believe - Well I have the lot, Intel Optane 64, Samsung 970, and this FEMTO M.2 - they sound different)

 

Tried to boot it from a M.2 USB adapter card - My Gigabyte Aorus Mobo Bios just would not recognize the drive. Only the Samsung 970 NVME on the adapter can be boot up on my Lenovo 6700k PC not the Gigabyte 10700k, So that test had to be abandoned.

 

Now I will try the Grounding of the USB port on the LPSU driving the Femto M.2 card tomorrow when another of those Grounding boxes arrives. I am using one at present but I do not wish to contaminate the ground with the other circuits I have grounded to this first box - rather use a new grounding box just for the M.2 drive. The M.2 drive is that transparent.

 

Will report back if improved Grounding can elevate the sound of this M.2 card further.

 

Happy Listening to All

What OS/player are you using now? With 300gb on boot drive I can entertain revisiting  Server 20xx although the license cost after trial is pretty steep.

Windows Server 2019 Core, AO 3.0, Fidelizer Pro 8.0, Minority Clean, Jplay Femto. Controller is Bubble Upnp. Local music is on Usb-attached HDD with external LPS. I also turn off Hyperthreading and Turbo when using Windows. Also cap the Frequency to 1.2Ghz.
