rickca Posted May 12, 2016 Share Posted May 12, 2016 Alex, the iFi iPower I got with the micro rendu says 9V/2.0A on the box, so I'm confused by your comment. Also when you reveal the technology behind the whateveritis, please explain why your device is superior to a conventional LPS in the same price range.

Superdad Posted May 12, 2016 Share Posted May 12, 2016 Alex, the iFi iPower I got with the micro rendu says 9V/2.0A on the box, so I'm confused by your comment. I appears that iFi has updated their iPower and that there have been two versions (and that is leaving out the early one that they used to ship with their product.) Here is the pic of the back of the box from the unit I got from Rich at Signature Sound about a month after shipments began. UpTone Audio LLC Link to comment

Here is the pic of the back of the box from the unit I got from Rich at Signature Sound about a month after shipments began. [ATTACH=CONFIG]26029[/ATTACH] iFi has clarified that the original iPower packaging contained printed spec/current ratings that were very conservative due to the non-completion of certification testing at product launch. That certification testing is now complete and all newer iPower shipments contain a sticker covering the original ratings on the packaging with the newer certified higher current ratings, but all previously shipped iPower units are identical and thus conform to the newer higher current rating too despite what is printed on the packaging. Their older ULN power supply that wasn't available separately and only shipped bundled with DAC/amp products is a totally separate product, and this new current rating does not pertain to that older design, only the iPower.

Hi Mikey: Thanks for clarifying that. I do have a programmable DC load machine (use it to torture-test JS-2s!), so I could put my 9V iPower SMPS wart on it and see how it holds up for a couple of hours at 2A continuos. Might be a bit stressful for it, but I am willing to sacrifice in the name of science--and to verify if it will be okay to use to power our new supply. I still think people will want to find a different use for their iFi since it is not anymore AC-mains-quiet than any other SMPS, and its improved output will be of zero benefit to the our piece. --Alex C.

I know you've said it's of no benefit to your upcoming special-power-sauce-supply, but the iFi is supposed to be quieter than the typical SMPS. That's on the power side, then? So the AC-mains side is just as noisy as most other SMPS? Can't a guy or gal get something, anything, for nothing in this hobby? (And where are the audiophile-grade hearing aids?)

I am interested in the result of your proposed stress test, however I agree that the iPower probably isn't the very best option for use in combo with the MPS.

rickca Posted May 14, 2016 Share Posted May 14, 2016 Don't know about shipping, but we intend to end the "mystery" of the tech and post pictures by the end of this week. Am trying to get the rest of my biz and e-mail under control first as I know there will be lots of chatter and questions. So we should have some interesting stuff to read this weekend?
