View Classified Jcat Optimo 3 Duo Linear Power Supply, Dual 5V / 3A Rails *PRICE DROP* Jcat Optimo 3 Duo for sale. LIST PRICE: $1,848. Original owner with low hours. Two independent, galvanically isolated 5V / 3A rails with matching high quality DC cables, perfect for Jcat USB and NET XE cards (up for sale soon) or an externally powered M.2 NVMe (for sale now). Excellent condition, with a couple very slight marks on the top right faceplate (See photos. I am very picky and I noticed this in the sunlight. The camera was zoomed in about 3x so they are hardly noticeable from normal distances). Hasn’t seen many hours so it could probably use some more breaking in. Optional Synergistic Research 4A 250V slo-blo Orange fuze for additional $90. Please see link for more details: https://jcat.eu/product/optimo-3-duo/ Buyer to cover PayPal fees if not using “friends and family”. I will cover the shipping costs.

Check my 100% positive feedback on US Audio Mart and eBay, username: Jazzebration Due to spending most of my time these days listening to analog, I am slowly disassembling my short lived, yet beloved, music server. Individual (mostly) items will start popping up in the coming weeks, so keep an eye out if interested. The following items will all be listed at some point: - Revelation Audio SSD / M.2 FEMTO (320GB pSLC) - Jcat Optimo 3 Linear Power Supply (dual 5V / 3 amp out for Jcat pcie cards) - Jcat USB Card XE *SOLD - Jcat Net Card XE *SOLD - Jcat Optimo S ATX Linear Power Supply I’m probably going to regret this, as I’ve never heard digital audio sound anywhere near this good, but I’m hoping they all find some good homes.

Powering this dac using phone charger sounds kind of dirty and the harshness hurts my ears, I've tested Power Bank and it's really clean as they say, but the quality is kind of claustrophobic and very poor in bass, the same I've read in reviews about IFI Power Supply and IFI X (and the same for the USB filter IFI Silencer+), now I'm plugging directly into the notebook (The USB Data and Power cable), I've clearly noticed that the sound quality of the E30 is better than the above options, sounding good soundstage, clean, accurate without any audible noise or distortion, I would say it's a comfortable sound, BUT I sometimes feel a pain in my ear, like a ''needling'', it bothers me a LOT! Believe it's some kind of noise or interference from the USB ports. Could anyone recommend a good Power Supply Linear that is good in the bass and brings superior to what I mentioned?

View Classified FOR SALE: HDPLEX 500W ATX Linear Power Supply w/ SR Orange Fuze + Isoacoustics Giai III Upgrades FOR SALE: HDPlex 500w ATX Linear Power Supply. https://hdplex.com/hdplex-fanless-500w-atx-linear-power-supply-with-modular-atx-output.html . These are very hard to find and have been sold out for months. I originally purchased this unit in March 2021 (arrived in late April) to power a music server build, but due to supply chain issues I haven’t been able to put everything together. As a result it is in completely unused mint condition. It has been sitting in the box nearly the entire time. Besides the power supply, I’ve upgraded the fuse to Synergistic Research Orange, and added isolation with Isoacoustics Gaia III feet (which required thread adapters which I ordered separately). All factory parts and cables are also included, as well as the ATX bridge modular input board. If you’d like, I can also include an adapter cable which will allow the pcie from the psu to power the secondary 4 or 8-pin CPU EPS on the motherboard. I’ve decided to go in another direction for a server and will not be needing the psu anymore. I was excited to use it, especially with the upgrades, so it’s a bit disappointing to see it go. Hopefully I can pass it along to someone who’s been looking for one of these, as again, they’re very hard to find. I’d like to sell everything as a package, but will consider leaving out the Gaia feet and lowering the price. But, in my opinion, linear power supplies definitely benefit from isolation, and these are some of the best on the market.

I have an extra spot on my LPS and a new cable modem with a wall wart that could be replaced… however, I don’t recognize this plug and can’t find it anywhere. It’s not the standard 2.1/5 plugs you see on most equipment. I figure that if I can find it, I can have an LPS cord made with this. Anyway, pictures:

After installing a Schiit Wyred between my office desktop and Wadia PowerDAC mini, I began to ponder using one in place of the USB charger that powers my Raspberry Pi Picore Player. The Picore Player streams radio and Pandora from the Squeezebox Server and my networked Vortexbox server. The Wyrd worked wonders on my desktop system. Has anyone used a Wyrd as an outboard power supply? Thanks and Happy Holidays to all.

I just finished this PSU for my CAT. Some figures measured from the AC receptacle (with +/-5% error I suppose) -when PC is off (in standby mode): 20W -when PC just starts (where the peak comes): 90W -when PC running smooth after boot up: 70W The circuit design refers to this: Linear ATX power supply - diyAudio with some change of regulators (I use LT1083 for every voltages, and dual 12V rails), basically they are the same thing just more capacity.
