I can't find any mention of Audio-gd using the new chip on their website. So until I hear anything definite I will assume the original chip is still being used.

From what I have read it seems the ES9018K2M is a lower grade of chip than the ES9018.
 
I have seen it advertised for $20 each!

 
Ah yeah now that I re-read the product sheet the K2M is not necessarily a lower grade chip it's targeted for mobile devices (hoping for a good phone with a good on board dac!).

Unfortunately I'm in the states, and even worse, I'm on Verizon!

Hey guys, quick question... how well does this amp do with low impedance loads? Mostly 32/40 OHM cans i.e. Grado's, Audio Technica and the like.

For the money my 15.32 drives my HE500s and mad dogs great which have similar impedances. I know it's a different unit but they have the same power output so I assume the amp stage is the same.

This amp does fine with low impedance cans.  I've used them with M50s, AD900s, and Grado Alessandro MS1s, all sound fantastic, just make sure you have it in low gain mode.

+1
 
I've used multiple low imp, high sensitivity cans in low gain mode with no issues.

I guess the only thing that's keeping me from buying this thing is its looks heh, don't like the buttons or the length of the device.
 
Maybe I should build my own case.

i don't like the power button in the back of the case

Has anyone compared the usb and spdif inputs on this? Impressions will be very much appreciated

I believe the general consensus is that the optical sounds better than the USB.
 
I thought so personally back when I still had my HP-P1.  I would run my iPod > HP-P1 > NFB 11.32 using a TOSlink between the 11.32 and HP-P1.  I thought this sounded better than the USB directly from the PC.  The SQ itself seemed a little better and then there is the slight popping issue at start and stop of song via USB that isn't present when  the iPod is the transport.
 
However, it seems that you can mod the 11.32 by disconnecting the power to the optical out and this seems to fix the SQ issues over USB for whatever reason making it sound much closer to the optical in (or the same)

Hey guys, I couldn't find this on audio-gd website but do they do returns?
 
 
I am trying to decide between a Audio-GD NFB-28 vs a Schiit Bitfrost&Asgard2 and I know Schiit does a 15 day return policy or something like that. I would like to do some comparisons of my own, and I don't know how best to do that.

i would go with the bifrost & asgard... performance, soundstage, musicality is all there...

Thanks for your suggestion. Naturally, I would like to know why you think so. Previous owner?
