Audio-gd NFB-7 - Page 3

post #31 of 148

NFB-8 is a good alternative if Reference 7 is too expensive.

I agree... It´s better business sense to keep making the flagship 8-chip model and the bestseller 2-chip ones. The REF5 was also kind of a middle product, being neither high end nor performance value. The dual Wolfson high end DAC´s also replace the REF5 very well, I wouldn´t be suprised if they perform clearly better as there is no stacking bonus to the SNR as with the 4 chip variant (4 chips via channel in balanced).

 

My next DAC will most likely be a dual Wolfson.

Opps I made a mistake....I meant the 8 chip Dac vs the 4 chip Dacs.

 

Oh well....the point is, its better to spread those chips out and stay at or below the sweet spot of 1K.

I have made up my mind to get a dual wolfson beside the dual mono balanced dac.

Three out of five of their reviewers on their panel actually bought the thing.  I do not think they deserve praise for canceling it. I do not feel so great about ordering something that has so quickly been discontinued.  I originally ordered an NFB-11 which was delayed and now discontinued. I then decided to upgrade to the NFB-7 and now it is discontinued. They have a long way to go before they can be considered a reliable company. I wish them well as a business, but they do not deserve praise for disapointing their customers, no matter how good their designs might be. It seems that Kingwa is like a talented but tempermental chef.  I am not a huge equipment swapper, but one of the factors I consider when I buy a more expensive audio product is resale value. It seems their older discontinued products do not sell on Audiogon. Yes, if they are under-capitalized and can't afford to purchase the chips they must consolodate. I will think long and hard before I buy another product from them.


I read the reviews on Pacific Valve and it was interesting to find that the NFB7 is the "warmest", "most musical", "least resolving" among the REF7/REF1/NFB7 groups. They also said that the NFB1 and NFB7 are like products from 2 different brands.

 

Short product life cycle and low resale value definitely doesn't hurt a company as much as delay delivery after payment. I think Audio-gd is being very honest by saying they don't have enough production capacity and have to make the decision of discontinue many of their products. If they don't, it would be like this: http://www.head-fi.org/forum/thread/461344/oh-where-oh-where-has-my-slim-arrow-gone-oh-where-oh-where-can-it-be

I cant beliewe TI charges anything near the list price of 1704 . Its produced on old - written off- tech, and everyone and his brother must be getting a huge discount buying those. Besides audio-gd stacks lots on top of each other therefore they can use their part of the chips-> lower inventory cost.

 

Unlike the 9018, where there probably will be a replacement in ½ a year. And what will happen if a new 1bit enters with a lot of halo effect, then you have a lot of expensive 9018 for no use :)

I doubt it´s very cheap... If it would be, why is it still only used only in most western hifi audio brands high end products (Wadia, Naim & co)? Also as a pure mono chip without a receiver it´s more expensive to implement than a Delta-Sigma. I´m also pretty sure R2R chips are way more expensive to produce than Delta-Sigmas. Many respected audio designers still think it´s the best sounding chip ever made. It was discontinued once, but because of the medical instrument/measurement industry wasn´t happy with the replacements they brought it back. It wasn´t brought back into production because of the audiophile (niche) market. The PCM1704UK is a sure bet as it´s the last "old tech" flagship still in production, so it´ll be usable for many many years to come. The ESS release schedule is pretty fast, I would be suprised if we indeed didn´t see a Sabre32^2 next year.

All he needs to do is design a custom receiver implementation to allow the Ref-7 to accept 24/192 and it will appease all the audiophiles out there that think they need this option.  In addition, further development of the DSP-1 module could never hurt.  Perhaps put a good size memory buffer on there so that the source has less or no impact on the SQ.

IPodPJ: On the chinese Audio-gd site there was a job offer for a software designer yesturday. I wonder what Kingwa is planning. The DSP-1 code is outsourced, so what could it be? Maybe an SSD transport or even portable gear? Interesting times...

I hope he will make the DSP firmware upgradable via the computers usb port.  Just pay a small fee, download the firmware, plug in your dac to usb and upgrade.  Even better, to be able to adjust the DSP setting via your computer/usb connection instead of opening the unit and changing jumpers.

I doubt he will do that.  It wouldn't be nicely packaged firmware that has been developed to install with server software like Squeezebox.  It would be raw and you'd probably need an older operating system to do it.  And if someone screwed up the installation, they could toast the FPGA.

Nicely packaged firmware...sounds like something a Software Designer might do....Hmmmm and just so happens AGD is looking for a Software Designer.

 

How about that....

You're dreaming.  It won't happen.

I´d rather put my money on a solid state transport with FLAC playback to replace the CD7-FV.
