It does to me. I have always believed the least amount of processing of the signal a DAC/CD player has to do the better the sound. It's why in a revealing system I have heard sonic improvements with CD's that are in good condition compared to scratched ones of the same album. Admittedly it's small and you need a good system to hear but it's there. I don't know why this is, I am not an expert but it seems that way to my ears. I would imagine the 120 doing the conversion after the fact would be a similar thing, perhaps Vinnie could explain why this is?

Do you hear a real difference between FLAC and ALAC ?  

 

I am asking this because so far I mostly use ALAC with my RWAK100.   may be I do the wrong format choice when I download ! :mad:

FLAC and ALAC are both lossless compressed files = smaller. WAV is a lossless un-compressed file = larger.

 

The FLAC & ALAC un-compressing is done by the DAP's processor at the time the files are played, which 'may' result in a compromise to the SQ and uses more battery power than WAV files which require no un-compressing to play and use less processor and battery power and 'may' sound better due to less processing. FLAC and ALAC should sound the same and may or may not sound the same as WAV.

I need help :

 

I have purchased an AK120 with B&H (USA) and it has been delivered to me out of USA.

at the moment i receive the device, i found that the power (ON/OFF) button was moving and making noise, i could heard noise when i shake the unit with my hands.

@ months after, i realized that it was not normal. then contacted B&H about the problem. B&H confirm me that my unit has a problem. i had 30 days to send back, but now it is too late, after 1 month, they would not accept to change my unit. they recommend me to contact Iriver. what i did : 

Please see bellow the reply of Jonathan from Iriver USA.

Dear iriver customer,
 
Thank you for providing us with all of the requested information including the picture of your unit. Please keep in mind that it is normal to have the ON/OFF button to have some play when you shake the unit. It is normal to hear that sound of the button moving. All of the units are designed that way and so rest assured, there is nothing wrong with your specific unit. If you have any questions or concerns please email us back at any time.
 
Thanks & Regards,

I replied him that i could not accept such problem for the hight price i paid to get the unit. I should receive a strong and good unit.

then he recognize that there is a problem on my unit, and that i had to return it and get it repaired.

I told him that i did not want my new device to be opened and repaired after only 2 months of use.

And that, as he told me that all unit has the same issue, and that it is normal, i did not want anymore the AK120.

I was ready to add money and get one the unit which has not the button problem : AK120 TITAN.

If not at least , they should give me a NEW AK120.

I refuse the issue of 30 days because : How could i imagine that it is not normal and return it within the 30 days ? while Jonathan the specialist of Iriver who knows more their materials replied me that that issue is normal.

 

Now i'm coming here to request for help : Iriver don't want to help me, and B&H (the supplier) has also refuse to change my unit.

Where can i complain against Iriver and B&H ?

Could someone help me ?

I'm not in USA, and far from there.

 

Thank you in advance for your help.

 

Samuel 

 

Hello,

 

thank you for having support me on this subject.

Finally B&H USA (the supplier) sent me a RMA and ask me to return to them the AK120.

I did that, then they asked me what i wanted : Refund or exchange.

i told me that exchange but not with the same type of item (AK120). i request for AK120 TITAN. and they accepted my request.

just now, i have received my new unit AK120 TITAN. 

Would like to precise that i paid nothing, that was done by B&H USA for free.

Thank to everyone : B&H is not bad.

 

regards

sam

DSD files can have up to 3 db of extra headroom before any clipping of sound will occur.
In downsampling to pcm format pluc 6 db is the usual level added to get the same levels.
It can occur that there will be 'overlevels' of .1 or .2 db, and that´s the crackling/clipping you hear.

Thank you for your answer! So is this normal on all the players? How would I go about fixing the problem?

I´v only experienced this clipping on two of my DSD songs. There´s nothing you can do to fix this problem, unless you are able to edit the DSD-file and set the levels a tiny bit lower. Perhaps A&K will fix this in a software update, but I wouldn´t count on it.

post #5154 of 6309

It is probably best to convert your DSD into 24/176.2 flac using audiogate which checks and fixes for clipping. Since Ak120 is not a native DSD DAP there is really no point to have DSD native files loaded in it.

Yeah most of my DSD files play great. Just those big dynamic jumps that get it. Hopefully they will fix the problem. Thanks again! I couldn't find the answers anywhere lol

Suppose they were embarrased that they had sent you such a dodgy unit but to send a Titan!? Lucky... should have asked for an AK240 and seen what they said .lol.

post #5157 of 6309

It wasn't that 'dodgy' and B&H Photo didn't make the thing. They are just a great source for goods.:bigsmile_face: I recommend my clients to buy their NAS's there.

post #5158 of 6309

Well, if things were rattling around inside of the device and they were prepared to ship him an updated model as compensation... figured there must've been something going on. Is pretty impressive for a retailer to go that far, am wondering if iRiver will upgrade me to a 240 for having to send my 120 back .lol.

 

Speaking of which the bug I had seems to have resolved itself, kinda.... new files ere being lumped into one folder all jumbled up but now that one folder seems to stay in a mess leaving me free to add other new files whereas before I couldn't. Is really odd.

Potential 320gb for AK120 :)

 

That's a good find! Pity I don't have a player that uses microSDXC anymore. Prices are quite reasonable too.
