For powering things like a lumin u1 mini, pi2aes etc. What is the best under $1k? Obviously sbooster mk2 and uptone lps 1.2 come to mind. Any others? Keces p8, Plixir Elite BDC are others I can think of.
Check out the Uptone Audio JS-2 and the Mojo Audio Illuminati v3. They pop up used for under $1k.
But the deal of the century has to be the Farad Super3. Very well reviewed. Check out the LPS shootout conducted on the whats best forum featuring the Super3 vs Sbooster and a few others, I believe it was translated from Dutch. I’m picking up a Farad Super3 later this week. Prices start around $500 and go up from there if you want upgrades fuses.
Wow! Those things are a LOT of money for a simple power supply and usually only good for one voltage.Look on Ebay for used industrial lab power supplies. Many to choose from for 100 bucks or less. Look for Power Designs, Hewlett Packard, companies that made top notch lab gear.I have two Power Designs power supplies, they will provide 0 to 60 VDC, up to 5 amps current and the power is very clean, well less than a millivolt ripple and the voltage is extremely stable even on a 6 place lab voltmeter. The model with the micrometer pots can regulate to within several millionths of a voltage once set. The voltage regulator is actually in an oven built into the supply to keep it at a constant temp. These are much better designs and much more versatile, plus your not getting ripped off paying the audiophile tax. Of course it looks like lab gear but just hide it. BillWojo
For my modem and router, I purchased two of these LPS’s – with heatsinks. The modem and router can cause the LPS’s to get hot if they’re working hard. Such as when watching Netflix or online gaming.
For the digital components in my audio rig, I purchased two of these LPS’s – without heatsinks. Since the draw is low with these components, the LPS’ never get above room temperature.
For my dedicated laptop, I purchased this one. Laptop’s require a different type of LPS to run correctly. It’s not a 19vdc vs 12vdc configuration. It’s something else more complex. I forgot what.
After-market umbilical cords are used with all of the LPS’s. Huge SQ improvement over the stock umbilical cords. Also, all LPS’ are plugged into power conditioners.
I purchased these LPS’s since they were affordable for my budget No complaints. The SQ is quite good. They’ve been problem-free for years. No doubt, the more expensive units are even better. There’s a lot of ways to lighten your wallet in this hobby.
dougeyjones, I'm in total agreement with you. And jaybe scoffed at the idea of industrial PS! The lab supplies I referenced are MUCH better than some ripoff audio supply with gold plated connectors and a fancy name to go with the astronomical price tag. Lab supplies have REAL specs, voltage drift is measured in parts of a millionth. Noise is in the microvolts or lower region. And they cost a hell of a lot more than $1000 when new. Those cheap supplies you guys reference have rudimentary regulation and would fail horribly in a electronics lab.
" Full disclosure, i am an electrical engineer . . . "
"I am 54, used to be a DJ in night clubs and sound tech touring with live bands and I can still ear the impact of every changes I make related to power… I would like to believe it is only perception/subjective but it is more than that for sure."
"I really believed for a moment that those three tracks were poorly recorded. With the LPS in place they sound just great."
Farad Super 3 looks like the real deal. Has some ultra-low noise specs and some new technology, EDLC capacitors. Check out the site's tech talk page and the shoot-out with other LPSs. No, I don't own one, but I might take the plunge.
I actually recently did a lot of research into this. I have a Farad Super 3 power supply on the way to replace the china ebay LPS I have for my Pink Faun S/PDIF card. I couldn't get the china/ebay ps to work well even after I rebuilt/upgrade it and experimented with different types of output capacitor (it had this really huge 4800uf cap on the output line, best we can come up with is the regulator circuit is really slow or unstable and requires a huge cap on the output to fix this).
The Keces has been said to be pretty good, but does not match the sound quality of the Farad. I would only get the Keces P8 if I absolutely needed that much current. 2 x 4A output or a single 8A output. This is HUGE and really is only needed if you are driving a computer type device or something like small monoblock amps (such as the Nelson Pass DYI project amps).
I liked the design of the Farad because it uses big beefy main power supply caps and very good post regulator caps. I looked at the JCAT power supply, but I really think that it's massively overpriced for what is actually inside. Inside only has 6 smallish caps and what looks to be an IC type regulator (like a 7912 or a LT varient). There is no discrete regulation circuit in the JCAT.
I have been waiting for an LPS better than the Uptone JS-2 to come along. There are now some claims the Farad is better from testimonials. Let's see how this pans out.
auxinput you are correct in thinking the JCAT LPS just looks to be a standard design with normal LT regulators inside. Nothing special going on there, while the Farad looks like a well thought out design.
I just looked at the
Mojo Audio Illuminati v3. Interesting device. Uses a Belleson regulator (which is a discrete version of 7912) with a couple transistors for added current (to get the 3A output). Looks to have a choke in there like the Uptone, but I don't know how it's used. It's definitely more than I would want to spend.
I received the Farad Super 3 and have had it burning in for a day. Obviously the result is not conclusive yet, but it isn't sounding bad. lol. Definitely did not sound good fresh (lack of bass and lack of "separation of instruments"). Was definitely better after a couple hours. I can report back here in 3 weeks if you guys want.
The Farad Super 3 is absolutely excellent! Burning in really resolved any problems with the initial sound. I also found that the fuse in this power supply is really important as well (I do not recommend Hi-Fi Tuning Supreme). The AudioMagic Supreme fuse worked well, but I have had an ORANGE fuse in the unit for a week and it sounds excellent!
The Farad is a really strong power supply and has excellent current. If you use this as a power supply for digital transport or a Pink Faun or JCAT card, you may get a warmer sound from your digital cable because there is no ripple or drop in voltage/current. Other power supplies that sound thinner may have different results on a gold-plated/copper digital cable. I did really close listening and, in the end, the full sound of the Farad was still the best.
I have not compared this to other power supplies, such as Teddy Pardo / Uptone / Mojo. The consensus I have read indicates that Farad is superior over Teddy Pardo and Keces, but I don’t know how it compares to Uptone or Mojo.
Farad is a slightly different design where it has two stages of power regulation and uses super capacitors as "batteries" in the post-regulation section. There really isn’t any lack of performance here. The Mojo looks excellent, but it’s more of a conventional type of regulator design that uses Belleson discrete regulators.
