It sound even better with Balanced.  :D

 

 


I didnt try with the balanced but here is my impression

 

At first I went with the preloaded song and the ck100 as a pair, not impressed at all , it sounds very digital losing that nice warm round egde of the ak100/ak120 , while being very very good in technicality I simply can't enjoy it at all . I tried the heir 4ai next , getting better there , some of the sound sig of the heir 4 ai is further amplified but still it sound just okay. Now then this may sound stupid to you but so far in I didn't use my own song , I copied in some of my own song , asked for a partere thinking that if It didnt sound good with this kind of lineup  that AK finally ******d up

 

 

 

I am officially poisoned and if I ever manage to gather the money to buy these combo , I will buy it . It was pure bliss , it is everything my brain and ears ever wanted from a sound signature , while I never hear that many high end desktop summit head fi , but this is probably one of the best I have heard to

You're possibly right. But from my estimation, the 4-pole connector goes like this:

 

tip - left hot

ring 1 - right hot

ring 2 - left invert

sleeve - right invert

 

Not sure how the ground is implemented if this is correct.

 

There is no true ground connection with the TRRS which is exactly why AK uses the adjacent 3.5mm TRS jack as a ground connection with their mysterious 'junction block' seen at the shows.

OK. I realize now I'm confusing balanced low level signal paths with high level amp to speaker/headphone paths.

By the way, has anyone who ordered an AK240 from a US dealer received theirs yet?

Ordered mine from a US dealer last Friday and received it on Monday. I'm based in the UK by the way.

Thanks for your reply. Seems there have been preferential shipments to certain dealers ...

As an aside, I much prefer Hifiman's implementation of the combo balanced/normal 3.5mm jack where you can simply switch from single ended to balanced with a physical toggle. I don't need any external converter cable. The same jack also accommodate normal cable. With AK240, in addition to using separate jacks with freaking different size that necessitates either a converter or another cable altogether, I also need to go into Setting menu to toggle normal vs balanced. As much as we knock hifiman's UI, the whole balanced design imo is much better thought out than iriver. Probably iriver is just too arrogant to "follow" hifiman's design, or to avoid patent issue (read: royalties). frown.gif

I will probably be able to share more impression on bal vs se later. Initial impression is pretty much in line with the Bal v SE experience on HM901 - wider sound stage, more clarity, higher power, less black background. And I don't feel AK240 bal has much material advantage over HM901 balanced.

 

Maybe a 2.5mm TRRS male to 3.5mm TRRS female converter like this will work? Not sure if the 4-connector poles for AK240 is wired the same way as the HM-901. I think I remember seeing someone posted that it is non-standard and different. So what will happen if you plug a balanced cable to the HM-901 and accidentally hit the switch to single-ended? Will that also cause a shot-circuit in HM-901 similar to that of AK240 if Astell&Kern had use a 3.5mm TRRS socket for balanced out and someone accidentally plug a 3.5mm TRS plug in?

 

So the balanced out from AK240 is on par with HM-901? Would love to hear of your comparison between AK240 SE vs AK240 Balanced when you get down to it.

I pre-ordered mine from ALO about 2/25 and was able to pick it up from them directly on Tuesday, the official release date.

 

I have heard from one person here that smaller dealers are having a hard time getting inventory.

Moon Audio seems to have the AK240 in stock.

Send an email to Drew from moon audio to confirm delivery date. He normally respond within a couple of hours. Good luck!

Anyone tried the streaming function yet?

 

More specifically I am interested in whether it will connect and stream via a wifi portable drive like the Seagate Wireless Plus.

Listening to Daft Punk's Random Access Memories on AK240->RxMk3-B+->LCD2.2 Balanced. Pure, Unadulterated, Bliss!!

 

The soundstage is much more expansive than the AK120. I do not need to turn up the volume as much when using the AK120.

 

I have not tried LCD-2.2 directly with AK240 yet. Waiting on the 2.5mm adapter cable.

I was finally able to load up my FLAC collection onto the AK240. The SQ on AK240 was way better for FLAC than on AK120.

 

I am have been playing FLAC files for close to 4 hours now. The battery has come down to about 75% only. So, DSD play is the power sucker.

The wifi streaming relies on a Windows/Mac program. In the program you can specify which folders/directories you want to share for streaming to AK240. So you would not be able to just stream from a wifi drive standalone. For it to work, hile I haven't tried, the drive would probably need to be mapped and accessible from the PC/mac running the MQS server program.

Don't forget to 'allow' your security to let the AK240 connect. After realising this, Wi-Fi worked and sounded like a dream. Very intuitive process. DSD takes a bit of time to load. See Judes UI video.
