Hifidelit Posted July 17, 2014 Share Posted July 17, 2014 What is the diy aspect - is there some assembly required by the customer? If it is a complete PSU then to sell it in the EU it should pass EU safety laws I believe and be certified as such. Link to comment
jtm Posted July 17, 2014 Share Posted July 17, 2014 From what I know it is a complete unit, no self-assembly. EU compliance? I asked that question some time ago and the simple answer is - no! (See post 10 in this thread) You get what you ordered and you have to deal with it. Same story with this unit or Keces or JS-2 which you can find in other threads here at CA. Audiophile aspects and sound quality may all be on the "safe" side with all of them, but these DIY units and start-up companies most probably never checked EU regulations IMO. (Just a personal guess, but always open to be proven wrong on this context). It doesn't mean bad product, but all the (electrical) risk it at your end ... Link to comment
Hifidelit Posted July 18, 2014 Share Posted July 18, 2014 I saw your post 10 and the answer and that's why I asked the question - what is the diy aspect? DIY means do it yourself. This appears to be a fully assembled psu without any safety certificate. My understanding is if they don't meet the certification they cannot be sold in the EU. I believe other markets have the same or similar requirements. I would have thought the supplier(s) would have to get certification to cover themselves if the worse happens to avoid prosecution.

I am not 100% sure ... but as this is not being sold in the EU; but sold in HK and then counted as a personal import then EU certification does not apply. You may as the end user be hit for import duty. Eloise Eloise --- ...in my opinion / experience...

Distinctive Posted July 18, 2014 Share Posted July 18, 2014 The problem here is the missing CE marking. This was discussed with Kenneth when I bought my Lumin PS. European Regulatory Requirements - CE Marking Link to comment
Audio_ELF Posted July 18, 2014 Share Posted July 18, 2014 The problem here is the missing CE marking. Well no; the problem (if there is one) is that it's not been passed for testing. The CE mark is just an acknowledgement that testing has been completed and the device is compliant. This was discussed with Kenneth when I bought my Lumin PS.European Regulatory Requirements - CE Marking As I commented above; Kenneth isn't marketing a product in the EU. He is marketing a product in HK which as an individual you are importing. There is a similar situation with other products including (at least original version of) the Berkeley Alpha DAC - this was only available in very limited numbers due to non-compliance with EU regs.

Eloise Well, this may still pose a problem with your insurance company if your house burns down and you have deliberatly used a PSU that is not CE marked that was found to cause it, I suppose. But as you say, this is the buyers problem, not the seller... Link to comment

greghifi Posted January 11, 2015 Share Posted January 11, 2015 Hello, I am interested in very clean power supply (15V, 3A) for audiophile grade headphone amp Holographic Audio Ear One http://www.holographicaudio.com/products/5/ear-one.html Can you make such in enclosure similar size as amp itself (silver alum color)? Thank you and happy New Year ! Greg Link to comment
Superdad Posted January 11, 2015 Share Posted January 11, 2015 Hello, I am interested in very clean power supply (15V, 3A) for audiophile grade headphone amp Holographic Audio Ear One Products | Holographic Audio - Swedish Hifi Can you make such in enclosure similar size as amp itself (silver alum color)? That headphone amp takes an AC supply--not DC as offered here. This means that your HA has the AC>DC rectification, filtering, and regulation inside its chassis. So all you need externally is a power transformer (size maybe 50VA to 100VA) with a 15V secondary. Nothing else is needed (well power inlet jack, switch, fuse, and jack/cord for output). You could go with a toroid transformer, or get fancy and order up a pricey R-core. But don't look for any regulated DC supplies to feel your particular headphone amp. UpTone Audio LLC Link to comment

I realize that I wished to improve what doesn't need to be improved, what seems fit quite well into contemporary audioshizophilephrenic trends well. Point taken and appreciated. Link to comment
