  Audio gd had been clear in that opening the case does not void the warranty - you may confirm with them.

Thanks for the clarification - wasn't aware of this

How would you change filters on the nfb15? I see no option to do this via hardware or software...

 
Which version do you have?  Mine (NFB-12) is by internal jumpers.  It'll all be documented in the manual.

  You could play around with the filters, but changes will be subtle.
 
If you really want brighter, you're actually wanting the NFB-11 (Sabre based instead of Wolfson)

 
Yeah maybe I should've gone with the NFB-11, I'm just looking for a little more "sparkle" with my Alpha Prime headphones the NBF-15 is too smooth for me I think.
 
Shame I couldn't demo them side-by-side prior to buying.  I like a musical fun sound, and am not keen on analytical "lifeless"  sound, that's why I went with the 15 rather than 11.
 
Maybe I'll wait until a local audio show is on take my gear and demo a few.  I am not buying anymore expensive Amp or DACs blind again lol.

The alpha prime is a really dark headphone..

Yeah that's why I need a bit of balance. NFB15 is not bright enough really for me. I've got a cayin c5 I may stick with that for a bit and sell my nfb15. I'm undecided thus far.

NFB-11 isn't much brighter.

Does the c5 provide enough current? underpowered orthos often sound brighter.

The C5 is awesome with the alpha primes, I'm listening to it now with my Fiio X5 dac . Fantastic.

I feel ive had the same experiences as you after hearing my he500s through a Oppo HA-1. The HA-1 is out of my price range though. The sound was so much clearer/more detailed especially the highs yet it was smooth and non fatiguing. My nfb15 almost sounded muddy in comparison

Here you go - jumpers are inside the case

I don't think it will do what you are looking for though.  NFB12/15 (due to their intended design) are neutral amps with a warmish full bodied tonality.

That was Mike's opinion.  Not one shared with many NFB-12 or NFB-15 owners.  Honestly - take anything Headfonia says with a grain of salt.  They take nice pictures - but most of the time I ignore the content of their reviews. It is one person's opinion ......

 

[Tostapane]

ok thanks for information . i have a k612 and i bought a k7xx .. i was going to buy an nfb 15 but i was worried for the vocals ( the best part of my k612)

 

[Change is Good]

I used to own the K612 and now own the K7XX. You need not worry. Great pairings with the NFB-15

Agreed - in the MSR7 thread someone from head/earphonia said they could tell differences by simply swapping cables.  They were all high end cables so.....i dont know what to think of that.
