SOLD: FS: Modded Fostex T50RP, Audio GD Digital Interface with DSP-3 (USB), Audio GD NFB-11

Recommended Posts

Item: Modded Fostex T50RP, Audio GD Digital Interface with DSP-3 (USB), Audio GD NFB-11
Location: Bendigo, VIC 3550
Price: Varies DAC/DI Combo is SOLD!
Item Condition: Very Good Condition
Reason for selling: Moving trying to minimize things to move with
Payment Method: Pickup/shipping - Cash, paypal (buyer covers fee), direct deposit


Both the Digital Interface and Audio GD NFB-11 (with Sabre32 ES9018 Dac chip) were purchased approx. 1.5 years ago the Audio GD DI has the upgraded clock which was installed at Audio GD. This was used to connect my computer to my receiver and to my headphones.


You can read the detailed specs on the Audio GD NFB-11 here: http://www.audio-gd.com/Pro/Headphoneamp/NFB11/NFB11EN.htm


You can read the detailed specs on the Audio GD Digital Interface with DSP-3 (USB only) + upgraded TCXO clock here: http://www.audio-gd.com/Pro/dac/USBface/Digital1EN.htm


Comes with BNC cable (to connect the DI to the NFB-11) and USB cable + Nice RCA cables to connect the NFB-11 to an amp or receiver for speakers.


Pretty much these modded T50RPs sound very close to the hifiman HE-6s I used to own, very close but in a closed headphone. (He-6 still sound better but they also cost much much more)

Modifications to the T50-RP can be seen here:

http://www.head-fi.org/t/583371/t50-response I purchased them directly from HDman, very detailed list on how he did the modifications and the parts he used. Only little flaw is that he cut out small notches on the original rubber/plastic headband to mount at one time a head tracking system for virtual surround sound. 


Looking for $220 ONO for the Audio GD NFB-11/Audio GD Digital Interface combo with cables (as I think it should sell as a single unit) and $200 ONO for the T50RPs. 


Pictures are available on request

      Item: Naim DAC-V1  - DSD DAC, Class A Head Amp, Preamp
      Location: Sydney Inner West
      Price: $1,150 plus postage
      Item Condition: 9.5/10
      Reason for selling: no longer needed
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info:
      This is a spectacular, versatile DAC offer from Naim which is a current model retailing for $3,150, although Melbourne HI-FI has an EX display model now for $2,400
      It provides:
      - DSD DAC via USB
      - 24/192 via optical, BNC and coax (has 5 inputs)
      - Class A Headphone Amplifier - It has been my reference amp  to drive my Focal Utopias, plenty of power, clean and engaging sound (typical Naim signature)
      - Fully analogue, digitally controlled pre-amplifier with RCA and Naim proprietary outputs
      - Linear power supply
      - Remote control
      The unit was purchased from Stereonet about 5 months ago. I initially purchase it for use as headphone amplifier, but it was so good that I sold my other DAC and preamplifier and made this the corner stone of my system. I am now downgrading pretty much all my system to collect some cash which is needed for unexpected circumstances not related to hi-fi.
      This DAC received 5 stars of What hifi and "best buy" on The Ear.
      These are some reviews:
      The unit presents as new, no marks or scratches. I dont have the original box but given the compact size it can be packed very safely and easily in a different box (I can use the one it was posted to me in)
      This is the original AD from Stereonet.
      (Note that there are no marks what so ever on it, as it would appear from the photo in the old AD. I will add some extra photos tomorrow.)

      Item:  Micromega MyDac RRP 500
      Location:  Loftus, Sydney ( Southern Sydney, 2232 )
      Price: $200ono + postage if needed ( do not have original packaging, but will send well packaged ).
      Item Condition:  Used, looking really good.  All it has done is sit there and work 🙂
      Reason for selling:  NLR, looking to try something different
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info:  Looking to sell my Micromega MyDac, bought from SNA a while back.  Hasn't missed a beat.  Just would like to try something different.  If you have a DAC of similar value would consider a trade.
      Link to the product...
      Here are a couple of reviews.  Here CNET call it an instant classic...
      Here is where Darko call it VERY good but not a classic.
      There are more if you would care to google.

      Item: Mytek Brooklyn DAC
      Location: Melbourne
      Price: $1,400
      Item Condition:  Excellent
      Reason for selling:  Changed tack - gone fully active
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info:
      Mytek named this the Brooklyn DAC - but it a lot more than that.  It is an excellent and very flexible DAC, and one of the first to support MQA, and with multiple filter profiles.  The specs in the picture below spell out better than I can the formats supported (up to 32 Bit, 384 MHz plus DSD) with output through RCA or XLR.  It is also a very flexible analog / digital Preamp, including phono equalisation, and excellent headphone amp.  All in one small package with an extremely versatile and informative digital display, and remote control of volume and key functions.
      Short form Stereophile review can be found here:  
      There is a longer print version from their magazine with more detailed technical view I can provide to anyone interested.  There are also many other reviews around.
      I bought this from a fellow SNA'r a couple of years back and have found it awesome.  Only selling (along with valve and solid state amps, speakers) as I have moved to an all-in-one active system.  You will find a lot of recent information on the DAC+ update - having listened to both I tend to agree with the reviewers that DAC+ is a small step up, but not one that justifies the premium of buying new.
      I have original packaging and am happy to post at purchasers expense

      Item:  PS Audio Nuwave DSD DAC
      Location: KEW 3101
      Price: $700 pick up cash or $730 shipped.
      Item Condition: Used
      Reason for selling: NLR
      Payment Method: Pickup - Cash, Paypal
      Extra Info:
      Purchased new by me from Magenta Audio in SA about 2 years ago. Has been put on rack and rarely moved, except for swapping cable etc. So it's in excellent full working condition.
      The build quality on these is fantastic. This is a heavy solid unit, that will shame a lot of the ordinary builds out there.
      I was using usb, coax and toslink and all work perfectly. The driver that is provided for USB on Windows 7 works perfectly - never a tick or dropout - unlike other Schitt out there
      I was using RCA for the first 6 months and then switched to XLR with positive effect - as my amp also has XLR input.
      I did notice a tiny nick/smudge on the underneath front corner when taking the photos, otherwise condition is excellent. Usual dust specs/ finger prints ...
      ***  I have the original box and manual so can ship if required. ***
      *** You will need to supply your own power cord as I was using an oyaide one ***
