iCAN Amp Review: A New Amp that Gives You More: More Bass, More Soundstage and More Detail - Page 26

does this have more power than the fiio e9 and if it doesnt what does have more power at around £300.thanks

Surprisingly, the specs of the iCAN are on the ifi Audio website:
http://ifi-audio.com/portfolio-view/micro-ican/

400mW into 32 ohms, 40mW into 600 ohms

Perhaps equally surprisingly, the specs of the E09K are on the fiio website:
http://www.fiio.com.cn/products/index.aspx?ID=100000017625376&MenuID=105026003

900mW into 32 ohms


From this I would conclude that the iCAN has about half the power of the E09K rolleyes.gif

However, you have not told us what headphone you are attempting to drive. What is its impedance and its sensitivity as this can make a big difference?

Some amps can swing the large voltages necessary for high impedance cans but cannot produce the higher current needed by lower impedance cans. For others the opposite can be true.

The sensitivity of the headphone also plays a part and this varies hugely. As you are requiring more power, can we assume you are using an insensitive headphone?

Hi, noob here about all the technicality but do love my music like all of us here. Do you think it has the current and voltages to drive the HD650.I'm looking to replace my E9 and the V2 iCan have gain settings that will also make it usable with my more sensitive iems without the hissing issue. Thanks in advance.

Sennheiser state the HD650 as having a sensitivity of 103dB (I assume per mW). This is higher than my T1 which is 102dB. The iCAN is more than sufficient for the T1 so it should be OK for the HD650 too.

Fiio don't state how much voltage the E09K can output but I'd be surprised if it is not enough given their claims for the device. If the E09K is not enough for the HD650 then either you are deaf or you soon will be.

Thanks for the feedback technobear. The E9 definitely have a lot of power and drove the HD650 pretty well. But on sensitive iems, there's little play room with the volume pot as it gets really loud pretty fast even on low gain. Therefore, I'm kind of looking for a solution and at the same time hoping to get some improvements in SQ with the replacement amp. Any thoughts if the iCan will be an upgrade to the E9. Thanks in advance.
