Hi, I'm looking to buy a new DAC that will mostly be feed using USB from a laptop. The setup doesn't need to be mobile so I'm considering testing out either the MFB12 or the Tubemagick D1. I'm not going to feed it with 96Khz audio over usb, only 44Khz so the limitations of the D1 shouldn't be a...

Hi all,   Hope someone here can help me.  I have some Beyer DT-880 250 ohms and bought a Audio-gd NFB 12 amp/dac.   I'm running Win 7 Ultimate, and have connected the NFB-12 via USB to my PC.   What an amazing setup when it's working correctly!  But the sound is just NOT consistent! ...

Interested in feedback from Head-fiers who have heard both the Audio gd NFB-12 and Schitt Valhalla.     I have a pair of HD650 and love em!  Bought a Audio-gd NFB-12 and enjoying the sound, but...it seems to be lacking umph.  I don't know how else to say it, the NFB-12 is very detailed, with...

I am looking for a DAC+AMP combo for my HD600, not sure which one should I go for, NFB12 or FuBar III(2011) (might get power supply for it), or any more suggestion? Thanks

I'm looking for a good entry level DAC to pair with the Matrix M-Stage soon and it seems like these 4 are really popular for beginners. I'm currently using a E7 docked to E9 so there's definitely room for improvement here. I've read some reviews for each and a few comparisons but there doesn't...

Source: http://www.audio-gd.com/Pro/Headphoneamp/NFB12/NFB12EN.htm   It is $200 right now + $36 shipping to USA I think. Is it worth it? It has dual wolfson dac chips and I'm eager.

I've been debating whether to upgrade my amp to a Cavalli CTH hybrid amp or upgrade my DAC+amp to the Audio-gd NFB-12. My current DAC is the Pure i20's DAC which has a Cirrus 4353 24-bit/192KHz DAC, and my current amp is a FiiO E9. Which one would give me the greater improvement over my current...

Hi everyone,    I bought a pair of dt880s 600 Ohms a few weeks back and have been enjoying them greatly. I'm looking into investing into and amp and a DAC and leave the hifi world until something breaks :P    I've read that tube amps are better for the 880s, I'm just concerned with the...

Hello fellow Head-Fi'ers,   I'm currently sporting an Audio GD Compass and am looking to upgrade.  I have a pair of Denon D2000.  I love the sound of the Compass with them, however I'm looking to upgrade the DAC.  I was thinking of doing the setup in the title.  Basically my question is...

Last month I got my HD 650 and last week I got my Audio-gd NFB-12. I tested the NFB-12 for a few days and like to share my experience. IMO NFB-12 is a well designed and made DIY work with extraordinary value. Before NFB-12, I had or still have Essence ST, OMEGA Claro Halo, some other sound cards...

Hello guys,   I'm looking for a headphone amp for my Sennheiser HD 650's and I'm on a budget of ~$300 USD.   I've heard that the NFB-12 would be a good amp on a budget for the 650s? Is this correct? If not, could anyone point me in the right direction?   I'll be listening via my...

  I just received a Audio GD NFB-12 from pacific valve.  I was hoping for an improvement over my existing audinst hud-mx1, being full size & seriously powered.   Well, physically it looks great, solid with a nice headphone amp.  The problem is that 44/16 music (which is 99% of mine and I...

  I posted this previously on "Full size headphone amp" forum but didn't receive any reply, I guess I was in the wrong place as I think it is really a DAC question. Sorry, I'm a noob here (though I've been around other audio boards for a while).       I just received a Audio GD...

I'm looking for a great DAC/AMP to drive my LCD-2 and T50 orthos in the office.  Looking for a very clean, grain-free presentation with ample headroom.   Of course the challenge is always that short of getting to a meet it's hard to hear these units at all, let alone compare side by side...

Hello all.  Looking for some advice on what I think will be an upgrade (for me at least).  I currently own the Fiio E7/E9 amp/dac combo - which I use exclusively with my desktop.  I pretty much swap my current cans around with it (Shure SRH940, Beyer DT 880 250ohm, and modded Alessandro MS1is)...

Hey head-fiers!   Just like the title reads, im interested in some new gear for my newly acquired HD650s. Mind you, i will be using my computer as my main music source so a usb-capable device is a must! My budget this time around is approximately 250, though i CAN stretch it to 300 if the...

Hello,   I currently have a Matrix M-Stage amplifier and an Ibasso D4 DAC.  I am strongly considering selling these two and using the money to buy an all-in-one amp/dac, and was hoping to find some impressions/comparisons between the Audio gd nfb-12 and the Beresford TC-7520SEG.  They both...

Hi, I've been lurking these forums for the past month figuring out what to get as my first set up. Last week I finally decided to get the audio-gd nfb-12 and a pair of dt 880 600 ohm headphones. I just started listening to this set up and I noticed when I have the volume knob past 1 o' clock I...

Hi,   A quick question. Can i connect the NFB-12 straight with my active speakers? it uses any opa at its line out? i have notice that is this price category most of them they use the opa2134.   I had the matrix mini and i got very dissapointed from the sound.The NFB-12 is at the same...

Hey, I'm going to be buying this DAC/AMP this week and want to know what would be advised for the cleanest/best sounding connection:    USB Coaxial Optical   Also, can you let me know if there are any additional cables/adaptors I will need to buy to hook it all up. Thanks in advance.  

Am I missing something and how is this set up? Do I need to get a sound card If I want to watch movies do I need a 5.1 sound card to go along with my set up?

I recently received my Audio-GD NFB-12 and it seems to randomly shut off. Sometimes it might be on for about 2 minutes before it shuts off, and sometimes it might be on for about 5 hours or not even shut off at all. When it shuts off, it usually turns itself back on after somewhere between 1-10...

I recently bought the Audio-gd NFB-12.1 to pair with my Q701's and after using it for a couple of days, I have to say, i'm not very pleased with what i'm hearing. I'm using the Q701's as my primary set of headphones and i find the sub bass to mid bass to be pretty deep and defined but the vocals...

Hey there, since I got my NFB 12.1 it looks like it prevents my Windows 7 x64 Prof. from going to sleep or shutting down. If I use windows the whole day without powering on the NFB 12.1 then sleep/shut down works fine. As soon as I once power the NFB 12.1 on (even if I power it off afterwards)...

Hello, I have NFB12.1 with Tenor 7022 chip connected through USB, and I am considering a little bit upgrade in sound quality. The headphones will be SRH1440. The monitors are M-audio Bx5a deluxe.   I am considering these options as upgrades:   a) sell NFB12.1 and buy NFB15.2 with Tenor...
