Used Universal  Roxanne demo and my 1st Gen JH13.

 

Listened with with Pro EQ on and off.

Cool. Thanks again.

Initial impressions of the sound quality, is that it's a definite step about the AK120, but still not as good as the HM-901.  There seems to be a slight bump up in the mid base region, making bass a bit muddy sounding overall.  Low bass extension is not as deep as HM-901, nor as tight.

Ah those SABREs. Well, one thing that I realized is for the first time, the 901 might actually seem like a complete bargain when the 240 is released. Nice.

I'm looking forward to hearing the AK240.  I'm sure the built-in headphone stage is going to be very good.  The question is "how good?"

 

I can only speculate that it will not be on the same level as an RX3, Continental, or SR71A / 71B.  It is not fair to expect them to be when dealing with an all-in-one portable solution.  Dedicated portable amps have dedicated boards the size of the AK240 (or slightly larger) DEDICATED for audio.  They are using top notch parts and have the space to put them in there.  And a battery supply dedicated for just audio - not shared with the LCD, SSD, USB, DAC, etc.  So I'd be mightily impressed if the AK240 output stage can reach those levels.  Ken told me that he thought the AK240 output stage was a big step up from the AK120's and  comes closer to the quality of some good portables out there - so that is promising.  But it was busy and hard to do good comparisons, which I understand.  

 

Besides that, he said the screen resolution for the album art was amazing (better than his iphone), and the UI was really slick.  And that in person, it looks much better and looks/feels the part of uber-high end component.  

 

So we'll see what happens - I am itching to hear it with a pair of LCD-3s and compare to the stock AK120.  Then compare AK240 to modded AK120-S/B + amp with the LCD-3s.  

 

If the AK240 can get close to that, then they deserve a lot of credit for their design (the price of it is another story and only you can decide what it is worth after you hear it for yourself, 

right?).

At 2000 or 2400 dollars, in this case, I would expect it to be as good or very near, to using an external amp. I understand the use of individual power supplies and so on and have designed amps and dacs myself but at this price I think a person should expect and get the best to both worlds.

The build quality is fantastic.  Real Carbon Fiber backplate.  Solid metal.  It's significantly thicker than the AK120, but not as thick as it looks in pics from the top down view.  It's an optical illusion.  Kind of like an isometric 3D view.  The AK240 is thinner than the HM--901.

 

That said, I don't like the styling of the AK240.  It's bold for sure, but it's not comfortable to hold with it's sharp edges, especially that lower right hand corner.

 

The Android based UI is simply awesome.  Fast, responsive, and very intuitive, especially for anyone with an Android device.

 

The single micro SDXC card slot has cards seating very flush to the side.  Nail-biters will have a tough time ejecting and inserting cards.

 

Initial impressions of the sound quality, is that it's a definite step about the AK120, but still not as good as the HM-901.  There seems to be a slight bump up in the mid base region, making bass a bit muddy sounding overall.  Low bass extension is not as deep as HM-901, nor as tight.

Treble has good extension, and very smooth, even with very sibilant music tracks I use to test for this one.

 

But all of these points are moot if the AK240 is going actually sell for $2400 USD.  It's a difficult sell even at the AK120's old price, IMO.  But it's simply way too much.  So you'll have to ask yourself how much you value a superior UI. 

 

Is the Superior Android based UI, smaller form factor, and better battery life really worth over $1000 over it's nearest competitors?  Not for me, but maybe for a few.  We'll see.

I am looking forward to more impressions but it seems at the asking price, this DAP should knock your socks off, and it doesn't appear that sound wise, it approaches that. Maybe it just needs more burning in. :^)

I suppose it also takes time for one's brain and ears to 'dial-in' to the real sound of a piece of equipment, and standing at a booth, for a few minutes, isn't quite enough for that. Still, I appreciate the preliminary impressions of those who have heard the AK240 and taken the time to post their impressions here, for our vicarious benefit.

Edwood, thanks a lot for the impressions. Do you own the 901 and have compared with the same iems? Not questioning the comparison at all, just curious. I found the AK120 to be colored and I wonder if the 240 also is, and to the same extent...

At least this time the output impedance is 1 ohm...

Yes, I have the HM-901.  I was using mine directly comparing the same audio files back and forth between the AK240 and my HM-901.

 

Don't get me wrong the AK240 sounds great.  Just not quite up to par with the HM-901.  But the HM-901 has a very slow and cumbersome User Interface.  The AK240 has a vastly superior User Interface. 

 

But the real kicker is that if the AK240 is going to cost $2400, you could instead buy an entry level HM-901 AND a pair of Custom JH Audio Roxanne's for the SAME PRICE.

The idea of universal 2.5 balanced roxanne and AK240 is very tempting, I hate my weak nature.

Hi Edwood

 

Many thanks for your impression. It helps to put into perspective than it is sounding great. May I know if your HM901 is installed with balance card?

 

Also, just wondering if you have tested DSD on two devices as well? It would seem that the DSD native playback will be more stable than the HM901.

 

For a moment, I thought the AK240 will be the HM901 killer.

Thanks Edwood for your impressions. I have heard the 901 and lovely as it is my preference ended up with the 120, from what your writing the 50% increase in SQ ain't happening so I guess more music will be added to my library biggrin.gif

Yes, my HM - 901 has the balanced card. 

 

Tested DSD yesterday,must be something wrong with the files used, had same hissing noise as it HM- 901 did with with them and. 

 

Firmware is not finished, Async  DAC connection wasn't working yet, but  it will be there.

Sorry for asking again... but did you have the adapter to test the AK240 balance out and was your impression based on balance out of AK240?  HM901 low gain should be comparable to the AK240 balance....I think I will buy an adapter to test the 240 when it is released...

post #690 of 8574

AK240 uses a separate 2.5mm 4 pole jack for balanced.  You have to switch via menu pull down.   Can't have both running at same time.   There were no adapters.  They had 2 Roxannes with one balanced and the other not.
