V=5
mA=8.33
R=600

W=0.04167

Or if iCan is class A, so on higher impedance load will it produce more power?

The iCAN is able to output a maximum 5V. However, there is also a maximum current which is apparently about 111.8mA (approx.)

So with a 600ohm can, there is no current limiting.

However with a 32ohm can, current limiting sets in when the voltage reaches 3.57771V (approx.)

Remember that the loudness of a headphone depends not just on the amount of power but on it's sensitivity.

The iCAN doesn't appear to put out a lot of power into a 600ohm beyerdynamic T1 but the T1 produces 102db/mW so the available 41mW can drive the T1 very loud.

Maximum power from the iCAN is available into a 45ohm load as this is the impedance at which 5V produces 111mA of current.

### Gear mentioned in this thread:

This little amp drives my HD650 like magic. The bass boost just adds body and life to my HD650. But I have a question, could someone help me on how to work the gain switches?. The sound is fine without it, but I just wanted to try it out to see what it'll add to the HD650. Can anyone help.. ?
The switches at the bottom will give you different gain settings, the configurations are illustrated there. I have set my switches to have 0db gain, for better control on the volume.

Mine was set to the positions,seen in the photo,when I took it out of the box. Suits my HE500 quite well.

Have been listening to my new iCAN Micro for couple weeks now. Before that I use the headphone output directly out of my iDSD Micro.

First of all i just want to say that iDSD Micro is great. One of the best gears i have ever bought. I buy and sell headphone gears pretty often just to try different things. that's what this hobby is all about, right? iDSD Micro is one thing i think i will never let go. It is just so flexible and good looking. Not to mention that it sounds great. I don't know how iFi guys were able to pack so many great features in such a small and beautiful package and sell it for a very reasonable price. Btw, they weren't joking about using iDSD Micro to drive the mighty HE-6. I tried and it sounds pretty good for such a small device.

Going back to the iCAN Micro. A lot of people will ask why one would even need the iCAN if you have already got iDSD Micro which has a very capable headphone output. After adding the iCAN Micro after iDSD Micro the sound becomes sweeter and warmer. The only complaint i had with iDSD Micro before is that it could sound a bit dry from time to time, and looks like iCAN is the perfect cure for that. I think it might have something to do with its Class A circuit. I am a Class A guy. My main stereo has a set of Pass Labs XA60.5 Class A mono amps, and i also use First Watt J2 Class A amp for my desktop system. To me a class A amp (well designed of course) just sounds more musical and more effortless. It brings you closer to the music. iCAN did exactly that. I also enjoyed the 3D and Xbass feature. For 90% of the time i listen at Xbass Mid setting and 3D Max setting. I really like iFi's implementations with both as their effects are subtle.

I am currently using this set as my office setup. I am completely satisfied and have no intention to make any change, nor do i think that i can do any better without spending significantly more money. I highly recommend this combo to anyone who is looking for a good and flexible desktop setup as well as with some portability. (i just took this set to London for a business trip and they worked beautifully. They didn't take much space in the bag and you can use iDSD Micro on the plane. :-))

oh, forgot to mention that i use this set to drive my Yuin OK1 earbuds as well as Hifiman HE-560. Both were driven beautifully by this combo.

iFi has indicated that this would be an improvement over the existing 9v wallwart.  This will provide improvement to iUSB, iPhono, iCan, etc.

Also, this can be used with other gadgets also requiring the same voltage and ampere requirement of the gadget should be within the iPower's capacity.

Hi,

You are indeed correct.

We will create a separate topic on the all-new iPower next week as it does have some nice things going on.

Cheers.

Has anyone tried this amp with a pair of AKG K712's? How effective was the XBass?

As I listen more and more to my new iCan, I love it more and more. :)

Just done my first review (rather impressions) on head-fi, and it happened to be the iCan...
In case you are interested...

One particular thing that I like about the iCan is that it can bring vintage headphones closer to modern headphones with the 3D & XBass switches. I have a Koss HV1 (w/cable mod) and now use it way more often.

Hey Everyone,

I have a question about Micro iCAN.

I own Nano iDSD with iPurifier and I am looking for an amp to match with my Nano iDSD. (I do have an amp - Cayin C5 but I don't think it will be able to compete with both Nano iCAN or Micro iCAN)

One of the my biggest question is that is the price difference of about hundred dollar between Nano variation of iCAN and Micro variation of iCAN worth? ( This is based on the pricing of newer batch that ships with iPower adapter. For the older batch that ships with normal ifi's low noise power adapter is only has a 80 dollar difference.)

Their I/Os are identical.

I understand that you have more option when it comes to x-bass and 3d function with Micro..

Have anyone tried both of them?

If so, does Micro hands down is superior to Nano?
