Hi Guys,

 

Since I received many requests from people about the availability of the 400W ATX power supply, I'm happy to inform you that it's available to order now with shipping around 15th of May.  This is a small batch, so if you had an eye on it, please hurry up

 

It can be ordered at the JCAT shop over here: https://jcat.eu/prod...r-power-supply/

 

Best regards,

Marcin

Just added one of these to replace a custom very high quality linear power supply with PPA Pico PSU.

My only regret not doing it ages ago.

Great great product Thanks Marcin

Thanks a lot - enjoy

Hello,

I use two 400 PSU for both my pc’s and two Jcat Netcard femto
Now with the new Jplay 7 I beleve that more and more the surrounings (hardware) play a vital role.
Looking at the devellopments of the Memoryplayer 64, there is great attention to PSU and filtering.

In my Audio Pc I use also the filterblocks of Core Audio. This company doesn’t exist anymore I beleve.

But i now there is stil great potentional in filtering the Jcat 400W PSU.

Like the virtual Battery Powersuply from MemeryPlayer. https://www.thememor...virtual-battery

My netcard femto, lynx AES16e soundcard, 12v power to the processor and the ATX line is now filterd by the Core Audio blocks.
We could do better!

Any ideas?

Hi Arjen, 

 

I'd recommend using a good power cord with the PSU

Hi Marcin,
Each PSU has an Echole Signiture Powercord. There are not a lot that are better. Only in de Echole range.

Also looking at the enormous effort Absolare is putting in its powersupplies is not for fun.

They also made a special PSU for the Total Dac. Unfortualy way above budget for me.

I also take good care of resonancecontrol for the PSU’s and grounding them properly.

I built a linear power supply for my dedicated computer. It's completely DIY. The cost of a JCAT linear power supply is very prohibitive in Brazil (one Euro costs almost five Real), so, I decided to construct one. Even though it isn't a hi-end item like the JCAT PSU (I also want a JCAT Femto USB), certainly the computer is the most sensitive item I have with respect to power cables. I have three dedicated cables here: Nordost Valhalla, Transparent PowerLink MM² and Purist 20th Anniversary. Each of them presents itself completely differently on the computer, and with a much greater impositiveness than in the rest of the system (integrated amp. and DAC).

 

If you have different power cables, I suggest to try them in different places of the system. You may be surprised by that.

Once I went to Nordost Frey II on the ATX supply and Linear 5v supply (FEMTO USB and SSD) everything changed. This is fed by a QB8 and a QX4. I have learned you can never do too much on the power side of things. I am even entertaining build my own ATX cables with high quality wire.

I built a 24-way ATX cable and, for this task, used the best 24-way cable that I found: the Kimber Kable 12TC. Besides that, I bought gold plated connectors and mounted it all by myself. This is one of the best upgrades I did in terms of powering a computer. The cable has double of the gauge and material far superior to the original tin plated copper. I really enjoy my computer.

Very good idea, although very pricy if you want to use really high quality conductor.... 

I'm currently testing new very interesting products that will be launched under JCAT soon: one truly unique that can be used in combination with USB & NET Card (but not only) and other are very high quality DC cables using pure OCC copper with special dielectric. Long story short: this special cable as an 8-PIN CPU cable between the 400W ATX PSU and the motherboard turned out to be one of the biggest improvement I've had in my computer audio setup. So, one more time, I've experienced that everything matters in high-end computer audio on the hardware side: PC components, power supplies (naturally), _all_ cables (SATA, USB, LAN and DC cables inside PC too, or especially inside PC!), vibration control,

[FelipeRolim]

Marcin and friends, in terms of vibration control, I don't know if you have already tested, but probably yes. If not, I suggest that you try to use cork under your computers and its power supplies (three individual pieces dividing the weight evenly). It's amazing what these three "feets" do with the result of the sound. Here, I plan to completely coat the inside of the computer with a thin layer of cork. I really recommend this test.

 

One tip: if the computer and/or the PSU have original feet, don't put the cork under your feet, but directly under the chassis, on the metal part. Avoid the original feet. You'll be amazed with how natural and rich it sounds.

I personally use insulators from a special composite material made by a Japanese company foQ. It's extremely effective:

Looking forward to the launch of the ATX cables. I couldn't agree more that everything adds up. I have my JCat PC Chassis on a custom mag-lev base with a reactive ceramic resonance control and the PSU on Nordost Sort Kones (bronze) made a sizable difference in imaging, soundstage and tone in my system.

Very nice!

Thanks Phxtriode. The secret is under the PCB, hehehehe. At the top there are 14 capacitors of 30F and 4 Nichicon Gold Tune of 10000uF. All done with point-to-point connection.
