Audio-gd NFB-10

If i remember correctly it does not beat the evo or mk2 (and for $400-500 they should be better). Go search the DI thread to be sure though I know it has been talked about. The clock upgrade is only for ES version. And yes I believe the WM version will benefit from a DI w/upgaded clock and PSU.

I had my recent NFB-10WM order delayed for the clock upgrade actually....

Thanks for the quick and honest reply. I have read through that thread, but have noticed a lot of mixed opinions so I thought I would try here. This is helpful.
 
What makes the DI so tempting is that it gives you a chance at getting a high quality psu for dirt cheap. When you factor in a nice power supply for EVO or mk2, its ridiculously more expensive. If the MK2 had an option of being fully powered by batteries (like the I2S Hiface) with the psu only recharging, it would probably be  a front runner. Spending that much and then still have SQ depend on a nicer psu upgrade is a tough pill to swallow.
 
Edit: Damn, thats's a hell of a desk setup Baird :)

http://www.tweak-fi.com/apps/blog/show/5029064-the-usb-to-spdif-shoot-out-review-part-2-teralink-x2-vs-jkeny-s-modified-hiface-vs-audio-gd-digital-interface gives a good comparison with some price-competitive converters such as a Jkenny modded hiface. Myself, I found the hiface not worth the money while the digital interface is a very obvious improvement. Too bad you didn't buy direct from Audio-GD as Kingwa would have given you a 30% discount on the DI ($98 for USB version) which is where I got that it is "cheaper than the hiface" from in my previous post. If you can afford it, definitely get the power supply upgrade for the digital interface it's about the same $/performance ratio as the digital interface itself. The clock upgrade available for the DI is only useful if you want to use the upsampling functionality.

Interesting so you upsample from the DI then run the NFB-10ES without oversampling?  In that case I wont bother changing my NFB-10ES order and instead will include the clock upgrade only in the DI which I will order later when my budget will allow.  Otherwise as a good friend once told me "no money no food"

You can upsample from the DI if you want, but it is set to native sampling by default. The NFB-10ES does not do oversampling afaik, which is measured like "8x" or "4x" but rather upsamples all content to 864kHz which is why it uses an 80.000MHz clock. The NFB-10ES as it is now comes with the upgraded clock hence its new higher price and I don't believe you can change that.

So if the NFB-10ES does the upsampling is there any advantage to having the new clock in the DI.  I am way over my head here.

I think the ES uses 8X oversampling in the digital filter (built into the DAC chip or the DSP depending on what design/parts you go with) which is different from upsampling the original file to another bit depth and sample rate entirely (before DAC processing). 
 
Peete.

Hmm, I think we both might be right. It looks like it upsamples to 864kHz as part of its jitter reduction mechanism (based on googling). If you look at the technical diagram from Sabre's site, it looks like it has an oversampling stage (or 2?) after that.
 
Here's how I understand it:

this is simply unacceptable I've been shamelessly under-quoted for build time yet again.

Sorry,and the factory final confirm to us that must will sent out your NFB-10WM at 11th April

the initial promise was that it would take 15 days to build and that was on 2nd Mar.
then I was told it'd be shipped this week, and now this... So thats 15->30->45 days... Grrr. Sent an email asking for the REASON for this bs.

Seriously, why can't sellers just quote the real build time straight up. It's not like they don't know the load on their factory.

LOL you are NOT the only one who has had issues with Audio-GD lying about build time...

For my recent order Edwin estimated 30 days - but personally I think it would be better to offer a time range eg. 30-45 days - it saves upsetting customers as well as reducing number of correspondences.  Its good for Kingwa that the company is selling well and sales are growing but growing a business can be very difficult in terms of finance, logistics as well as customer relations.  Burson also has a 3 week wait on the HA160D, but they obviously are a bigger company with simpler product lineup and better cash flow - they don't need payment until order is ready - but they can afford to do this not only because of their size but because of the simplicity of their product lineup.

speaking of cashflow. If you order, just say you want to pay 1/2 upfront, 1/2 just before shipping. Edwin was prepared to accept those payment terms, but I ended up paying everything within a week of ordering. Yay for me...
I don't advise doing that and getting a 30 day shipping delay as thanks for improving their cash flow.
