Linear Power Supply Recommendations!

A good friend told me to buy a professional lab rated LPS as they are cheaper then Audiophile ones and made to a higher standard. 

I used an Sbooster with my Auralic Mini it's built like a tank and was a solid improvement. Not familiar with the Ferrum HYPSOS.

I've been extremely happy with Farad for my DAVE.  Don't worry about international shipping. it was invisible. Good exchange rate now.

That seems reasonable, but incomplete.  Did they give you any more specific information, like maker name, specs to look for, sites to shop?  Just buying an LPS because it's cheaper doesn't seem like much of a guarantee of better performance.

A linear power supply (LPS) is not the same as a switching power supply (SMPS).

I use vintage regulated tube linear power supplies but that’s another story!

Thank you @jond and @carlsbad2 for your recommendation.

@noromance
LOL..I am not going to venture tube LPS for Optical Bridge. I got the tube magic where it matters the most (phono).

This should be considered one of the best in the world.

Teradak and LHY good options, not crazy expensive. There are many more expensive options. Like anything, find a good match for the level of the rest of your gear. At some point, diminishing returns.

There are multiple options available for <$150 USD that provide solid voltage regulation and filtering with measurable ripple being <10μV and usually half that or less. That won't prevent some from making this exercise seem more expensive and extract whatever the HiFi market will bear, but that should be expected. This recent video should prove both interesting and useful:

10 Power Supplies Measured

HDPlex from Small Green Computer - 4 outputs, 2 are voltage adjustable.

Uptone JS-2 is a choke based lps with two outputs, differs from the usual resistor/cap lps

Thank you @trivema, @fthompson251 and @sns ….exactly what I need. LHY, HDPlex and Uptone makes dual outputs LPS.

I will see if i can did up the information been a few years since i looked at them. 

one thing to note the lab rated equipment has to meet very hi standards, standards that are not required for most equipment in the audio world, The ones i was looking at are the ones they use in the Calibration lab on the Navy repair facility i work at. I'll see if i can get a hold of the guy in the lab to get the brand. 

You might want to send Teddy Pardo an email and see what they have. I bought one of their LPS’s for my Node and it works great.  The sound is noticeably better and there is no background noise at all.

Thanks @glennewdick for any additional information you can share.  It's not that I believe there are no possible sonic benefits to an "audiophile" LPS.  I do believe you can be an audiophile at any price level, though, and the most appropriate LPS for a $1000 DAC may not be so for a $50,000 one, and vice versa.

Is this how a PS Audio power plant works plus the DC to AC conversion? I have a PP3 for my preamp  dac and steamer. 

@tee_dee

Not quite, PS Audio power plant essentially a AC regenerators that create a clean and stable power supply for your audio equipment. Here is the simplified explanation on how PSA power plant works,

1. AC to DC Conversion

• The incoming AC power from your wall outlet is first converted into DC (direct current).

• This step removes noise and fluctuations present in the incoming AC signal, which can degrade the performance of sensitive audio equipment.

2. DC to AC Regeneration

• The Power Plant then regenerates a new, pure AC waveform from the DC power.

• This regenerated AC is low in distortion, stable in frequency, and free of noise and voltage fluctuations.

• It essentially acts like a high-quality, local power generator for your audio system.

3. Voltage Regulation

• The regenerated AC is precisely regulated to maintain a consistent voltage level.

• This prevents your equipment from being affected by voltage sags, surges, or other irregularities from the power grid.

4. Additional Benefits

• Low Impedance Power Delivery: The Power Plant provides a low-impedance source of power, which helps your connected equipment perform optimally, especially during dynamic peaks.

• Protection: It offers surge and over-voltage protection, safeguarding your audio gear from potential damage.

By using the PP3 for your preamp, DAC, and streamer, you’re ensuring that these components receive clean, stable power, which can improve sound quality by reducing noise, enhancing dynamics, and improving clarity.

A linear power supply with a DC output is a type of power supply that converts AC (alternating current) from the wall outlet into clean and stable DC (direct current) power. This type of power supply is often preferred for sensitive electronics like audio equipment because it provides a low-noise power source.

A linear power supply is not going to improve the sound quality of that device whatsoever.

PS Audio Powerplants only contribute to line pollution if anything. This fact has been verified by independent measurements.

@lalitk - I just ordered two MCRU LPSs for my ifi Neo Stream and my Router. I ordered the base model for both the streamer and router. I only use the Neo Stream as a streamer (not the dac). Also, I’m using an ifi Power X on the streamer and the router so I’m very curious to find out how much of an improvement I will hear once I hook up the LPSs to both components. After I receive them and they break in I’ll let you know what I hear. 
 

keep searching for the sound. 

Teddy Pardo… i’m up to five and contemplating a 6th…. banish the wall warts ( smps ) and if you can’t do that get them on a power conditioner on opposite leg of delicate analog dedicated line….

@helomech Do you have a beef with PS Audio or are you genuinely unknowledgeable about the technology, perhaps repeating totaly insccurate posts form someone else with a beef?  

Don't repeat fake news.

Jerry

@carlsbad2 

Fake news? Why, because you bought into their marketing? Your personal truths preclude any and all contradictory data?

Might do well to read it before dismissing it as fake, though I bet you won’t:

And BTW, the Earth is round. 

I used an SBooster with the Geshelli Labs Dayzee DAC and the improvement was noticeable and positive. Once enjoyed it was not the same without it.

Either build one using a Sparkos Audio Power supply board or buy the 12v one from SBooster. Both are game changers. 

+1 for Teddy Pardo dual power supply.

I am using one with Bluesound Node N130 and Chord DAC to positive effect.

I have also had success using MCRU and Swagman Labs PS, but not sure they offer a dual supply.

You have asked for LPS….
 

but if you are looking for a clean power supply take a look at ifi products. 
the ifi elite power supply is quite quiet.  

Just received LHY (Jay’s Audio) LPS80VA dual output 12V/5A Linear Power Supply. Going to break-in for next 5-6 weeks and then compare with stock wall warts came with my Opti Bridge. If I hear improvements, then I will venture into comparing LHY with other LPS recommendations in the thread. 

Uptone JS-2 appears to be most versatile LPS with on the fly voltage adjustments and good long term investment. 
 

@lalitk I would be interesting to see a direct lps comparison, love my JS-2.

Forgot to mention JCAT Optimo lps, very nice quality lps, I use the Optimo ATX with my custom server.

For anyone using lps with various components, DC cables also important. I've built and or used a variety over the years, best have been Mundorf Silver/Gold wire with Oyaide connectors.

@sns

JCAT Optimo ATX is a serious piece of gear for a custom server, definitely not your average LPS solution. I used to own Optimo Duo 3, it was paired with Telegartner Gold M12 Ethernet Switch. When I added Telegartner Opti Bridge 1000M in my system, the M12 switch kinda became redundant because Opti Bridge on its own does a fabulous job of not only blocking noise gremlins but also renders much of M12 Gold Switch virtues. I believe in Less is More…so Opti Bridge 1000M (ahead of my streamer) with a good LPS appears to be best way forward.

I just ordered a pair of FTA Metis LAN cables to try it out. They will go head to head with Telegartner MFP8 IE GOLD LAN cables.

A direct LPS comparison would be interesting, especially between the JS-2 and maybe something like the Paul Hynes SR4/SR7 or Farad Super3. Each has its own design philosophy, from regulation to component selection.

And you’re re absolutely right about DC cables. A quality LPS is only as good as the cables feeding the components. The LHY LPS supplied with decent quality DC cables but they are certainly not in same league as Mundorf Silver/Gold wire with Oyaide connectors. I believe Mundorf Silver/Gold wire known to have a pure, detailed, and revealing sound much like my all time favorite - JCAT Signature LAN Cable GOLD cable.

Have you experimented with shielded vs. unshielded DC cables? Some setups seem to benefit from shielding, while others sound more open without it.

@lalitk For too long I'd assumed DC cables couldn't be that important, big mistake, on some equipment makes similar difference as AC power cables.. I haven't tried any home brew shielded DC cables, just light twist on the Mundorf. Doubt I'd be ever be tempted to try shielding on the Mundorf, prior off the shelf DC cables shielded, Mundorf far more open, transparent than those. Using the Mundorf DC on JCAT Network XE and Sonore OpticalRendu, both powered by Uptone JS-2.
