To dispel some of the power supply myths:Linear power supplies are not "noiseless", the cheaper ones with simple voltage regulators are much noisier than quality SMPS.In the old days SMPS would add system noise by injecting carrier frequencies back into the AC power supply lines, with that noise then travelling to other audio system components. Moderns SMPS don't have that problem anymore.SMPS have better regulation and significantly lower output impedance that contribute to better SQ.
Yeah, Hypex doesn't have anything that would work. I looked into this a number of years ago when replacing my Linkwitz Pluto modules (3886) with SMPS supplies. I ended up using Connex SMPS300RE. After purchasing six of them, I finally found three that worked well and continue to do so. The other three I threw on the shelf to collect dust.
Made in FranceThe components of this power supply are of first quality: Metal Resistors 10 capacitors filtering 2200uF / 35V Voltage Regulator LT1083Thus, this regulated linear power supply developed by our team comes to compete with more expensive solutions.Equipped with a 100% Aluminum case, two Jack DC 5.5 / 2.1 & 5.5 / 2.5, this power supply with an extremely stable 100VA transformer even under heavy load, and will allow you to make the best of connected audio components requesting from 15V up to 4A.
Effortlessly powerful.If your system’s power supply is unclean, background noise affects your sound quality.The iPower cleans this up, addressing the problems at both the output and input stages.It makes your sound flow cleanly and effortlessly.
The iPower makes music come alive with incredible low-floor noise and adds detail originally lost through conventional power supplies that are often just mobile phone chargers that have no regard for quite power.The iPower is at least ten times quieter than previous iFi power adapters, twenty times quieter than audiophile linear power supplies and one thousand times quieter than standard wall adapters.
Quiet! Active Noise Cancellation+ (ANC) at work!Exceptionally quiet power. The measured noise floor is 100x quieter than the Common Noise Filter.
Have you ever found yourself making a basic circuit that is so simple, that you say to yourself, "it's so simple I will just make it from scratch on veroboard..." It works so well and is so useful, it becomes an integral part of many of your future projects. Before you know it, you have hand-assembled on veroboard the same circuit a dozen times. Well that's what I have been doing whenever I needed a source of ultra quiet (battery-like) single-rail DC power in the range of 5v to about 32v and current under 1amp. I use this countless times for low noise headphone projects, DACs, etc.Well, I sort of got tired of making them from scratch and worked with JPS64 to put it on a simple 50mm x 75mm board the following: a CLC filter, an Easy-Peasy Juma cap multiplier, and a 78xx regulator, and throw in some smoothing caps, snubbers, output bypass caps, and LED power indicator, and input/output terminal blocks. I typically use a 12v 1000mA Class 2 transformer wall-wart ubiquitous with routers and switches that we accumulate over the years.That then powers a clean DC-DC step up converter to about 4v+ regulator dropout (circa 2v) above our needed voltage. So for example, if you need a clean 18v supply, add 5v or 23v as the DC-DC stepup output. Put that into this unit, and let its cap CLC filter, cap multiplier, and voltage regulator give you a clean source of 18v with ripple as low as 4uVrms (if you use a TO-220 formatted TPS7A4xxx LDO regulator). If you can live with 50uV noise, a simple 7818 regulator will work fine. I have used this on countless headphone amps and the noise floor measures flat like a battery. Absolutely no mains hum gets through...
