The Astell & Kern AK120 - Page 346

post #5176 of 5746
I asked A&K US directly (spoke to a human being!) and they said it is designed to work with any USB charging device. I then said how about my iPad one and they said it was perfect. I have been using that since they OK'd it with no ill effects. It does seem to take a similar amount of time to charge as to being plugged into my MacBook Pro.
Hope that helps.

And you can use the USB adaptor that came with your iPhone/iPod plugged directly into wall too.

I use 5V, 1A to 500mA USB wall charger.

Perfect!  Thats exactly what I was hoping for.  Thanks gents!

500 mAH is the safest bet (USB Standard). Charging at a higher rate might impact the battery life and the longevity of the battery in the long run (although your unit may charge faster as a benefit).

Guys/Ladies,

 

Anybody tried the AK120 paired with the Audeze LCD-X or XC who can advise if a good match, with 22 Ohm it seems like a perfect match in view of the 8x rule but worried it might drain the battery as they apparently are power hungry...?

Ak120 impedance is 3, and it is a terrible match for LCD's which require a powerful amp. Ak good for IEMs very bad for most full size cans, especially planar Magnetics.

Don't know what's the most headphones you've tried, but they power HD700 with 150 ohms very nicely.

Can't say I tested many, so I probably should say from what I read. Planars are a no, no for sure and I've heard Senn 650s are also not a good match.  One day I will try plugging in my LCDs and see. 

 

If you search what Vinnie Rossi of RWA, says about AK and full size cans it is the same thing as I did. He is an expert and very well thought of in the Audio world.

 

The AK is a stellar product for IEMs.

well on most parts you hardly see anyone using a non portable full sized cans straight out of a standalone DAP, maybe except HM901. Though I've seen a few who does with AK100/120 and liked it as well.

Yes, I'm waiting for Vinnie to see if it's possible to mod the firmware to allow HO in the RWAK120-S.
But in the end we should still judge and trust with our own ears smily_headphones1.gif

True, just that Audeze does confirm that they should be easier to drive and actually mentioned that they are ok with portable devices compared to their previous models  and also other Summit end headphones, thought it would be interesting to know if AK120 could get decent or actually very good sound out of the Lcd-X or XC not saying that IEM would not be optimum which they ofc are....

i can report that though my T5P's do sound better out of my amp with the 120 connected right out of the 120 they give a really good account of themselves. I am actually surprised how well the 120 drives them!

Don't have the AK120, but own the AK100 MK2 which has that similar 3Ohm impedance. Using the Alpha Dogs is definitely lacking in power and sound is very, "soft" throughout. But it works very well with most of my other headphones (i.e. not Alpha Dogs! :p) In fact, I was surprise with the synergy with my Perfect Sound Didos which are very sensitive/low impedance full-size headphones!

Agreed.

Anyone ever have the problem that AK120 can't play 24/96 Flac file?  I'm not sure whether it due the file problem or the foobar picture attachment that I attach it.

Mine's never skipped a beat. Love it.

Using it with Ultrasone Edition 8s now...amazing!
