yup. i'm using the usb power out from micro iusb3 to power the idefender.. prefer it over using a separate 5v ipower....

@iFi audio if i have a ipower, i should not consider dc ipurifier 2 since ipower has the function built in? am i right?

my experience is the reverse... with lps-1.2 powering the ifi chain, i get less dynamic, sound is thinner/weaker.. i took it out within 5 mins. Not sure if anything done wrong, it's a definite NO from what i hear. my setup is different from yours. you may want to consider how i connect, from...

How about up position? With everything else in the chain

The now white burst u r experiencing is from Idefender n igalvanic, without the micro iusb? If it happens on all 3 setting, I will believe it's a faulty unit..

I think it is doing exactly what this thread is discussing.. https://www.computeraudiophile.com/forums/topic/37034-smps-and-grounding/ will change mine to the dc spark connector and hear if it has similar improvement *on second thought i might just leave it in the usb slot. as the fit is...

thuanb, nice to see you here :dt880smile: i notice groundhog when connected to micro iusb, it adds extension to the highs. not sure if it's only for my setup that has this effect, need someone who has both to give it a try. i connect the ground via one of the usb power port.

From my experience, Igalvanic pairs well with Idefender with external power source. It sounds better. Maybe u can try comparing the 5v Ipower against a micro USB cable from micro iusb3 powering the Idefender.

I have gotten another igalvanic from canjam. now i'm using micro iusb with igalvanic. Did not encounter any white noise, but i'm facing audio dropout when the igalvanic isololation is in the middle position. up position solve the problem but i will continue to troubleshoot further as to why this...

edited the above. previously i mention "dropout" but it is not correct. "lost connection" is the correct word. when it happens, the SSpeed led on igalvanic will be power off. only the power led is lighted.

somewhere in aug last year - bought igalvanic bundle. about a week after i bought the bundle - idefender gave way. cannot power up anything. - 1 to 1 exchange with shop on idefender this year feb - idefender gave way again. 1 to 1 exchange with shop. noticed igvalanic have random lost...

that time i only have igalvanic, i'm using a usb power dac and it will poweroff/drop off randomly. all 3 settings has the same issue. i'm using the igalvanic for months without any problem. it's only when the idefender gave way then this problem happens on the igalvanic. not sure what is...

keep us updated on the findings. previously i have problem with my igalvanic and it persist through all 3 settings as well, and it only happened recently.

have you tried turning off the iso ground on iusb3? does it help?

GHoldridge, do you use idefender for the iG3 in your chain? because of some problem, i have swap my iglavanic bundle to micro iusb. but once you know the improvement IG3 brings, it's very hard to do without. so i'm considering whether to purchase another IG3 and stack with iusb, and how should...

Any idea if the iPurifier you used in your chain make any improvement? done any A/B with and without?

Hmm.. Have u look into ur mac power adapter? There's grounding actually but only certain plug type gives that..

to those who owns a nano/micro iusb3 and IG3, which is your preferred order of connectivity? nano/micro -> iG3 -> DAC or IG3 -> nano/micro -> DAC?

looks like my experience is not an isolated case, to IFI rep, when idefender is in the chain, is the switch on igalvanic suppose to stay in the middle or it should be flipped downward? can help to check with the engineering for answer/feedback?

FYI the faulty Idefender I had was outputting at 4.5v under load. The new one is around 4.79 under load which I think is much better. I'm using PortaPow usb meter.

trying to get ifi to clarify on their post. anyway i replaced my idefender, the bundled idefender seems to be faulty/not able to handle the load downstream(igalvanic + my audient id14). It's good that it died and i can replace it with another piece. also i notice there's some material difference...

can you clarify what you meant by this? connecting iGalvanic to idefender is considered non usb compliant? then why is this bundled in the first place?

Looks like my Idefender is faulty. now there's no power for downstream when external power is used.

i prefer the sound with idefender providing power to iG3.0, powering my DAC(audient id14). looks like i shouldn't be powering the idefender first before turning on my pc... will update more about it another time.
