Audio-GD NFB-11 - Page 17

post #241 of 987

Very good point, didn´t think of that... Makes sense! Interesting to see if they find out the what the fault is (hardware or software).

Hmmm, well I use active Swan M200s right now as my desktop speaker and Woo Audio 6 as my headphone amp. The EMU 0404 USB allows me to connect both of them.

The WA6 doesn't have a loop out either so I'd be able to use the NFB-11 for only one of them (outside of unplugging and switching from Swan M200 and WA6) from what I can tell.

 

I am sort of glad I waited after hearing about the current USB issues which I know will be sorted and Kingwa will make good on the units. RIght now I may stick with the EMU USB 0404, decent cheap and versatile for my setup. Not sure how much of an upgrade it would be either.

I further discovered that in the Audio-gd DI, there is a RAM chip server as buffer. One can find that in one of the Audio-gd DI's picture in Audio-gd's site.

 

Not sure if the RAM chip is there in the NFB-11.

Doing the following (in sequence of importance, try the next one if the previous one does not work) will help:

1. In Windows 7 Advance System Setup, set the processor to prioritize to "Background Process"

2. In Foobar2000's Preferences -> Playback, set both Replay Gain options to "none"

3. In Foobar2000's Preferences -> Advanced -> Playback -> Fading, set all options to 0ms

4. In Foobar2000's Preferences -> Advanced -> Playback -> Full File Buffering, set as much RAM as you can afford. i.e. 50000K if you mostly have 1 flac file per track, 350000K if you mostly have 1 flac file per disc.

5. Make sure your hard drive have at least 10% free space and defrag your hard drive (Auslogics Disk Defrag is a good, free tool). If your hard drive has less than 10% of free space, "weird break" will occur even if you have set (1) to (4) above

6. Try using another USB port on your computer

7. Convert each tracks to individual flac/ape file, avoiding delay induced by reading 200-300MB flac from hard drive at once.

8. Buy a USB 3.0 expansion/express card and use the port from it. Not that the USB 3.0 standard/bandwidth will get to use, but because all USB 3.0 cards require special device drivers which have higher priority in Windows than the default USB 1.0/2.0 HUB drivers which Microsoft hasn't update since Windows XP service pack 1.

 

For me, the "weird break" disappears when I reach Step (6) above



Interesting.  Also, from the DI thread:

First you need to make Speakers as the default to trick windows 7 into not interfering with your sound card or spdif digital out device. Then you should uncheck everything that can be checked in the "Playback tab." Then disable all the recording devices in the recording device tab. The obvious is use "No sounds" in the Sounds tab. Then finally in communications use "do nothing." The sound just changes to something I couldn't believe like I upgraded a new sound gear.


The interesting thing is, if in the playback tab, I click on Properties and turn off all the supported sample rates, it still works. Makes me wonder what these settings actually do.

 

Edit: #4 in the list above seemed to stop the drop-outs for me when I set the buffer to 512000 (half a gig of RAM).

For those waiting, I did get an e-mail from Kingwa stating that they were delayed - looking into the reported USB problems. No ETA yet.

post #246 of 987

I'll probably buy one of these once we get news about the USB issues. Afraid they will be sold out or there will be a price increase by then though.

post #247 of 987

Just email them that you are interested, and that you would buy it if the usb issue is fixed. If not fixed, you don't want to buy. Simple tongue.gif.

For fix USB problem: necessary to disconnect Intel SpeedStep and Intel C-State - power saving up technologies on matherboard, and also to disconnect built in Wi-Fi the module. The sound on USB subjectively is pleasant more. For those who can face a similar problem - use for diagnostics DPC Latency Checker, whether this utility will show at once is in system clashing on USB devices.

post #249 of 987

That's a veryyyy ugly workaround, I will not disable Speedstep & C-state on my workstation (i875k overclocked to 4ghz - I guess that'd be a 50w raise to my power consumption)

I don't even know if Speedstep can be disabled on my laptop...

 

I Hope kingwa will find a real fix in the unit =/

 

I might ask him if I can change my order to a dual wolfson NFB10 ... is it feasible ?

Use for diagnostics DPC Latency Checker - http://www.thesycon.de/eng/latency_check.shtml

Thesycon’s DPC Latency Checker is a Windows tool that analyses the capabilities of a computer system to handle real-time data streams properly. It may help to find the cause for interruptions in real-time audio and video streams, also known as drop-outs. The program supports Windows 7, Windows 7 x64, Windows Vista, Windows Vista x64, Windows Server 2003, Windows Server 2003 x64, Windows XP, Windows XP x64, Windows 2000

Kingwa told me he has a fix, so you shouldn't have to do anything with your computer.

 

By the way, I've set up the NFB-11 in my rather humble living room speaker rig with Parasound Zamp and Paradigm Titans. Normally I use the Fun A (with WM8741 and OPA Earth) as the DAC/pre-amp.  While it's not as resolving as my main rig I find it easy to get a feeling about gear.

So, Currawong? How does it sound?

+1  'specially since I just joined the pre-order queue for Batch 2.  smily_headphones1.gif

Question:

PC ~--> NFB-11- DAC-Out-RCA--> Millet Hybrid MiniMax --> Beyer DT990 600Ohm = OK

PC ~--> NFB-11- HeadPhone-Out--> Logitech Z-5500- 3.5mm analogue Line-in -->Stereo-Out -->Z-5500 Speakers= Good to Go??

Can I then switch between the 2 outputs?

TIA

Vpsporb: Yes. The switch on the front will do that for you.

Will be a week or two before I think I will post any impressions but so far I have the impression of "sharp and clear" without being harsh (except initially) and true to form for the ES9018 seems less source-sensitive. It might indeed a good combo with a good tube amp.
post #255 of 987

 

I'm Good to Go then...nice!  I just have to have patience for NFB-11 impressions... which are taking too long.. btw. lol

 

I just hooked-up a "HotAudio Bitperfect USB DAC" last night, and I must say.. I quite like it compared to my PC's "Asus XonarD2- PCM1796"  

 

I eagerly await my NFB-11..and fully expect it to knock the nylon/cotton coverings off my pedal extremities! smily_headphones1.gif
