Why doesn’t Emotiva build a quality power supply, either Lineare or Switching? How many low quality wall warts are in your rig? How many pieces would benefit from a low noise, low electromagnetic field? There is money to be made here. High quality power supplies with the backing of Emotiva would be beneficial to both Emotiva and us the end users. I’ve been researching this field lately and there are but a few quality low cost suppliers. Many of which are in the EU. It’s a wide open market at this moment. Audio enthusiasts are purchasing more and more low power but high sensitivity products. An example would be gear similar to what @klienmj and I have purchased lately. Network player, DACs and other items. I'm not an engineer but how much work would be required to build one out of an A-100 amplifier? Anybody have any thoughts or comments? @keithl lonnie Dan Laufman ? |

I have thought about that alot. A supply that you can just splice your equipment into and get rid of all those vampires around the house. A house needs to be wired with another set of outlets that just does 12 & 5 volt.

Anybody have any thoughts or comments? @keithl lonnie Dan Laufman ? I’ve wanted something like this for years, I’m currently trying to find 5V devices whenever possible and power them from USB chargers. One of the Leviton AC outlets I used in the Credenza has USB and I’m powering my Harmony Hub and 8 Port Gigabit Switch from there, saving two bricks, and freeing two outlets. However, a unit that could set the voltage of each output would be nice, it could have a standard output plug with cable/adapters for various device connections. I wouldn’t want anything bigger than 1U and probably prefer 1/2 rack width, I don’t have that many bricks in one place so a half dozen outputs would be more than enough. Maybe the DC-1/PA-1 footprint for me, but I might not be as worried about ultra clean power and noise as you (I haven’t heard any negative effects), a good standard power supply would work for me (as you say switching or linear, whatever specs well). Or build it into a full 1U rack unit with filtered AC outlets as well (probably not the purist device you’re looking for). |

AudioHTIT , I think there really is a large hole in the market. I’ve seen everything from cheap brick PS and wall warts with plenty of noise to excellent SMtO sps-500 with switchable voltage outputs with 5A selling for $500 ( or haggle) to $1200.00 lineare PS with super clean super expensive parts that may have a little more hype then effect but sell rather well. And everything in between. Sbooster has a very good reputation and offers a wide variety of outputs. The SOtM is a switching PS done exceptionally well with minimal noise as far as I can tell and lineare PS have been around for some time, they have had great results. I’d love to have a quality PS at a much more reasonable price and with the backing, warranty and support of a company such as Emotiva. Then there’s the market that would like a quality low noise multiple and selectable output. One more question, why plug a few hundered to a few thousand dollar piece of gear into a $5-6 PS?

If you do some looking around you can find low noise nice linear power supplies like TeraDak. There are a lot of companies selling these kind of stuff. Sonis safe to say Emotiva won't bring anything extraordinary from what is already available.

I think it’s because it’s a niche product.

Why jeopardize its performance by including an inadequate power supply? I liken this to people who replace their Emotiva power cords. Don't you think Emo would supply cords that worked properly? Products that have crummy PS are normally not so great themselves so the ones that need a fancy PS are the ones whose performance would be worse than the upgraded PS. |

Its not that the PS is inferior but its proximity is at fault. Some of the most well engineered products have their PS as far away from any critical circuitry as possible. But unfortunately its still inside the same case as those circuits. Move that magnetic field away from the main components is a better solution then just shielding and such. No? Isn’t this where KeithL flies in with my fair dust and blows up my whole theory? 😋 Most every producer of hi-quality gear makes a PS for said gear to minimize harm to any audio signal. “Do no Harm”theory. Cost prohibits placing a quality PS outside the original case. I don’t want a $50. Wall wart as quality parts cost more most likely for a serious PS thats quiet in every sense. |

Manufacturing to a target mark, a particular group or price point requires sacrifices in many areas. We aren’t the market of price no object, otherwise many cost cutters would be removed. A superior $10 part where a $2 part would suffice. I think you see mypoint. Of course we don’t want a $300.00 PU either, although many are in that price range and much more. Im just trying to stir this topic as it is often overlooked. A quality PS can bring improvements to your setup, more to some and less to others. Nick |

I agree it would be a product I would buy but I do wonder if it would be a niche customer base?

Nick (note - I cut and pasted your other reply to me below so it could all be in one post) Valid point I do understand. Its not that the PS is inferior but its proximity is at fault. Some of the most well engineered products have their PS as far away from any critical circuitry as possible. But unfortunately its still inside the same case as those circuits.

Cost prohibits placing a quality PS outside the original case. I don’t want a $50. Wall wart as quality parts cost more most likely for a serious PS thats quiet in every sense. Regarding the proximity of the PS - so if you get an upgraded PS for your amp or preamp or DAC or whatever, how would you connect it? That means you would have to disable the device's internal supply and connect your own to it. That seems like a warranty-voiding action. Also, if proximity is so bad and thus the PS should not be internal to the main box of the device, then wouldn't it seem those devices that use wal warts should be superior? If manufacturers can do that cheap external PS for cheaper gear and make people have to put up with it then why wouldn't the high-end people do the same thing - just make an external PS and make the consumer put up with it, especially if it improves the product? Regarding your other point about selecting parts priced to specific target end pricing, I understand that. But like you said, let's call Keith (or Lonnie or Dan) in here to ask them if the PS they put inside their equipment is in any way not up to par or inadequate, or the performance of the unit could be audibly improved by "upgrading" that power supply. I am guessing they would tell you the PS they build is appropriate for that unit. Any incremental improvement with upgrading it or making it external would not result in an appreciable audible improvement. That's not to say that there are not crummy PS out there, but my opinion is when you get into gear that makes you stop and consider the effect on your wallet if you buy it, their engineers have also put a lot of thought into the PS and have built it with what is appropriate. |

One is from TeeaDak 9v that I got out of ebay and a 15v also out of ebay. I have them for three and two years respectively with no issues. I would have to trace back the purchase to find out who was the seller and country of origin if that really matter. |

There are some products designed to be used with an external power supply, such as my LH Labs GEEK DAC and my ultraRendu. The microrendu and ultrarendu are not even sold with a power supply...you either choose one of their options and buy it (adding to the base price of the micro or ultrarendu) or choose someone else's. With the GEEK, it came with a basic option but LH Labs was pushing their LPS/LPS-4 power supply as an "upgrade" for those who wanted something even better. I didn't opt for that because I felt their pricing was way too high at the time. Used ones now sell for reasonable prices and I'm tempted. But, before I do, there's a cheaper option I am likely to try...just $50 and it is returnable if I don't find it to help. I do like the option of trying something different and I am convinced some of them actually help. I am also confident some just help drain a person's wallet. Mark |
