Micro iUSB3.0 Impressions Thread

[lithiumnk]

Hi, Ok. Seriously my bad. 24 hrs later the violet desktop mode light came on. I obviously get confused with all the colourful lights on the hugo2.
So now I can recommend the device for use with the hugo2. Yes the sound quality is bettered...I am also using the igalvanic 3 with it. The two together are an audible improvement over stock hugo2.

Hey
Sorry for late reply...
I never had problems with hugo2 and micro iusb3.0.
I am happy it worked out for you
Both galvanic and iusb3.0 improves hugo2 sound a lot. Its impossible to use hugo2 with a stock usb cable after using ifi devices..

Thanks for the input. Agree with you completely. BUT there is room for improvement... I switched out the supplied power supply for 9V from an hdplex linear power supply and the sound got meatier and more analog sounding. ( ifi may not appreciate this....). Did plenty of A/B testing to satisfy my ears.
BTW, how do have your set hooked up? Mine is micro iusb 3 to galvanic to chord hugo2 digital USB input and USB power from micro iUSB 3 to hugo2 power input.

Galvanic is supposed to be before micro iusb3.0.. pc>galvanic>iusb>hugo2 for data... power is fine...

Naah, all good, why wouldn't we? If you've found something that works for you better than our stock power supply, by all means tell people about it!

Cool find, thanks!

Yes, galvanic isolation comes before everything.

Thanks for that, I've swapped them around now, sounds a bit better. Next I'm going to haul out my intona isolator and do an A/B test and post my results.

Please do let us know about your findings!

Some USB filters have a variable input range to work, so can I use a 12V 0.5A Linear Power supply for iUSB3.0? I just want to filter the noise from an USB cable (not to power a DAC or something). I have a not used MCRU LPS made for Chord 2Qute and the output has to be somewhere at 12V/0.5A (like 2Qute is rated). Since I am not using it, I would try it.

If it's within specs, we see no reason why this wouldn't work.

Yes, the LPS it is in spec. So iUSB3.0 works with input voltage of 12V instead of 9V without overheating problems or something?

iUSB3.0 is 9V but can accept 12V.

What cable do you recommend for iUSB3.0 output to the DAC (Chord Qutest)?

What cable do you recommend for iUSB3.0 output to the DAC (Chord Qutest)?

Did you plan on buying it? Or you have it? For nano version standart cable is good enough from pc to reclocker so i suppose same should be true with Micro... From reclocker to Dac its more of a question is your budget and Silver/Copper preference.
P.S If you get Micro usb can you post impressions between standard and Uptone power supplies?

Yes, I want to give it a try, but I guess I'll do this next month. I already have a decent cable from PC, more exactly QED Reference USB A-B 3m, which I plan to insert at the input of iUSB3.0 but the question is, from the output to the DAC which would be a decent cable? Gemini 3.0 has a USB 3.0 type B connector while my Qutest has USB 2.0 type B. I might try to add a Gemini first gen though.

Regarding your comparison request, I will try micro but I do not have Uptone LPS, I have USB Regen and I can do a comparison with them. But my ISO Regen is powered by a normal power supply since it requires 6-8V DC. For iUSB3.0 I have a LPS of 12V which I can try. So I can compare the following:

1) ISO Regen + switching cheaps PS
2) micro iUSB3.0 + included PS (I guess iPower 9V)
3) micro iUSB3.0 + MCRU LPS for 2Qute (12V, 0.5A) which I am not currently using and I can try it with this one.

I have no idea if a USB 2.0 cable affects in any way the DSD128 playback which is the highest rate I am using. Qutest is not plugged to a USB3.0 port since my Motherboard does not have free USB2.0 ports.

Oh i thought you have one... i like how Nano and Micro sound. Lot more weight, speed, energy and depth to the sound, but for some reason it sound very hot, very aggressive. Want to know if its because of standart power supply or not.
Well any comparison is good for me.
