Couple of question about for NFB-12 owners. 
I'm in the market for an amp to use with my laptop, since it has a rather shoddy soundcard by default. I have a Xonar DX installed in my desktop, so the output and soundstage differences are quite noticeable. I was originally considering the Fiio E17, but then I found out that the NFB 12 exists, and I think it would provide an both an upgrade from my desktop and a mobile rig. 
Would you recommend this approach? I currently own a SRH440 and an AD700, but am looking to grabbing a DT770 in the future.

You won't be disappointed for sure. And now that the NFB-12.1 is out, great opportunity to get it.

I wonder if the 12 and 12.1 sound the same?  It be neat if the people that already have the 12 could send it in and paid 15 dollars for the update to their models.

I think their new one just wanna make user operate easier. 
$15 really fair enough, while someone who has NFB-5 but does not using OPA's feature would be jealous spent $130 hehe..

Have already emailed King-wa to ask if that would be an option, and what the cost would be.  Will advise back if/when he replies.

Given the cost of shipping both ways plus the materials cost for a new front panel and switches, it would probably be cheaper to sell your old unit on the forums and buy the new one.

Have there been any impressions of this amp with the HE-500? 

 

[eclipes]

I think you're better off with the Lyr.

Care to elaborate? I see you have a nfb-12, have you heard a lyr and prefer it over your nfb-12?

What would be the better source upgrade for me? (Cavalli CTH or Audio-gd NFB-12)  gives some advice about various cans that work well with the NFB-12, satwilson, post#7.

Would the NFB-12 have ample power for the 600Ω DT 880?

 Did you see my link above, Beyers 7-9, 250ohms-600ohms..OK...DID YOU SEE MY LINK ABOVE?

I assume you have read LiqTenExp's opinions via the provided linc. The HE-500 is much easier to drive than the HE-6. Given the extensive list of excellent cans the NFB12 can enhance, although not specifically mentioned, I would think the HE-500 would be very happy.

I have personally not liked either of my more recent 600 ohm Beyers (T1 and DT880/600) with the NFB-12. Soundstage and treble extension have suffered in both cases. Admittedly, I do have the early production NFB-12 without user-adjustable filters, so a newer 12 or 12.1 with the filter settings may prove to be a better pairing.

Try up-sample to 96k. I use SoX for the up-sample, it's a good formulation, low distortion.
Do not use the USB because it doesn't really transfer 96k to the DAC.
I've tested this seriously, and I've also informed audio-gd about this problem on this thread.
But the reply is not to my point and I'm fairly disappointed with them. I've also E-Mail them about this problem, they didn't even bother to respond my email.
Yes, the USB receiver chip would tell your computer that they can handle up to 96kHz data, but Audio-GD doesn't set the chip right, so the receiver chip will not send right information to the DAC.
 
 
Either optical or coax is fine.
 
You'll find that it much better this way with NFB-12. Mine is also old version without filter setting.
