Hello folks,
 
I had the NFB 11.32 for a few days and perceive it as very harsh on the treble.
Have any of you experienced the same problem?
 
 
I'm using it together with the hifiman he-500, a headphone which haven't been harsh sounding with other dac/amps I have tested.
 
I'm wondering if it can be a burn in related issue? It's been playing for maybe 30 hours or so.

 
How are you connecting the 11.32?  I tried the HE-500s with the NFB-11.32 & NFB-16 and the highs were smooth.

Via usb, with the supplied cable. Driver settings on 32 bit /192K

Are your music files recorded at 192k? With my MAC playing iTunes the music did not sound right when I had it set like this.

That's what I was thinking as well S....Always output to your native file.

I did change the settings to 44,1K/32 bit and then to 44,1k/16 bit. Unfortunately, not much of an improvement either way
 
Thanks for the advice anyway^^
 
I'll guess I just let it play up to a hundred hours and hope a divine intervention by the holy spirit of burn in.

That is weird Plux.  The A-GD gear I have tried with the HE-500s all spank them well with everything smooth as butter (NFB-10.2 as well).  You are using the supplied usb cable?  I remember in the 15.1 thread the supplied cable has to be pushed in tightly for a good connection (on the dac side).

Hmm, the cable seems to be working just fine and it's properly inserted in both ends. Though the cable itself appears to be of inferior quality, I'm quite sure it isn't the cause of my problem.

Have you written to Kingwa to ask if perhaps there is a problem hardware wise? The 11.32 performs well with both sensitive IEMs and more than adequate with LCD3. Not harsh at all. With the LCD3s I can turn the volume up to almost 1/2 way on the pot with high gain and its really sweet.

^^   ^^
 
BTW, I' use both USB and TOSLINK. The USB cable was almost $100 and the Toslink $20 at Radio Shack and I swear I see the same one on Amazon for 6.99 LOL

No, I haven't done that. Maybe I should if the sound doesn't improve.

Haha, Those Amazon prices always gives you the feeling you have been ripped off.^^ What $100 usb cable do you use, BTW?

okay i just got my audio-gb 11.32... i am using it on windows 8 and the drivers 1.22 which downloaded from audio-gd site... the amp portion is not that loud... my fiio e9 on low gain is louder than the 11.32 on high gain even though i think the amp portion for the 11.32 is about twice as powerful than the fiio... so what is the solution?? or that the warm nature of the 11.32 just makes it seem less loud at full volume? according to the audio-gd site, with asiio there is a sound drop off... i increased the buffer rate to 8192 and the sound volume did increase a bit but i am still confused that why is the fiio e9 louder than an amp twice the power... confuusssiiinnng. Tried it both with he500 and hd650 and fiio e9 is louder on low gain than 11.32 on high gain. Do i need to open something up or what??

The NFB11.32 is applied the ALPS exponential volume pots, compare to the normal linear volume ports, the exponential ports had around 4% output while the volume is on 12 o'clock, but the linear port have 25% output on 12 o'clock.
Maybe this is the different?

I would be suprised if the E9 used a linear volume control. 15A seems to be the default taper for headphone amps.

i actually max the volume out on both amps to test the difference, not on any other volume pot position. Doing so, the e9 is simply louder even on low gain than the 11.32 on high gain. I just need a confirmation from anyone else who has an e9 that this is also the case with them, so that my mind it at ease although it is loud enough for me well below the max volume for 11.32. For a layman/noob like me, louder volume= more power so that is why i am a little confused over here as 11.32 should be twice as loud.

All can say is "natural". Maybe the best under-$500 DAC/Headphone amp that I've heard. This a steal for $340. Take a while to break-in, after that pure bliss. More than neutral, like said, "natural".
