Reviving an old thread here. Just had the DSP-1 updated to Firmware v7. It is a big improvement over the last firmware V5 for this particular DAC. The slightly artificially processed sound is gone. It is now very organic, much improvements in the soundstage and imaging, tonally more neutral...

For those curious about installing the new 2014 firmware and driver on the DI-V3, I have installed them on the DI-V3. It works although playback is only available via WASAPI and not through ASIO for now. Kingwa mentioned in an email that the ASIO only works in 32bit output so not applicable to...

Try this link: http://audio-gd.com/Pro/dac/USB32/USB32EN_2.htm   The firmware v11 also contains older firmwares http://www.audio-gd.com/USB32firmware.rar   It should have all the files inside.

I tested the new firmware and driver on the DI V3 even though it's meant for the DACs only. Here's the feedback I sent to Kingwa about this.   "Dear Kingwa,   Just want to give feedback on the new USB32 firmware and driver 2014.   I install the firmware on the DI V3 supply SPDIF to the...

Quote: The Links are the same as above. I downloaded the Firmware file and it has firmware #10 in it. 

Quote: Just to chime in. I've updated to the DI, and have no problems at all. Other than a silly mistake which I did earlier. At this point tin time, I can only say the update brought some improvements in the soundstage (wider, deeper), balanced in timbre, better layering and separation of...

Tried the new firmware and the new driver. While there are some improvements in the sonics (better separation, soundstage and refinement), there's a new bug or strange behaviour. My DI-V3s is used as the primary output from my PC. When I first installed the new driver, output from Foobar ASIO...

The DAC-19Mk3 is still one of the best DAC you can have. I actually have a DAC19DSP which I managed to convert to accept the DF1704 and PMD100 digital filters as well as the DSP-1.    For what it's worth, I find that the earlier filters to my ears sound better. The music flows better and...

Just another brief Update:   I've installed the TCXO upgrade from Kingwa into the DIV3s. Could've kicked myself for not ordering it together earlier.   The TCXO definitely improves on the DI-V3s. Greater sense of instrumental colours, greater sense of ambiance and details. There's weight...

My apologies to all who may have been waiting for my update. Been really busy on a shoot so hardly had time to have a propere listening session. Originally intended to give an impression of the DI-V3s against the DI-V1 in the DAC19DSP (with the PMD-100 mod as well as the DSP-1) and FUN.  ...

Just a short update. It's been 150 hours of burn-in. Pretty much left it power-up since earlier listening when I first got it. After that I switched back to the SPDIF feed from my Juli@ card. I switched over to the DI-V3s just now just to get an impression of the sonics and if there's any...

Quote: No, I don't. Only the DI-V1. The DI-V3 doesn't have any upsampling function. Kingwa mentioned that since the jitter is so low, he felt a DSP3 isn't needed to reclock.  I did however, ask if it was possible if the USB32 be incorporated into the DI-DSP since I really like a DI-DSP...

I received my DI-V3s yesterday. In the package were the spare firmware, an LED which I supposed is for changing to a less brighter one than the one installed on the DI-V3s, along some resistors to modify the DI-V1 PSU to power-up the DI-V3s.    Initial impressions are the DI-V3s sounded much...

Judging from the pictures, I think the new DI-V3 is a modified version of DI-V2 with the USB-32 module soldered onto the earlier DI-V2. I did ask once if it was possible to modify the DI-DSP with the USB-32 chip bypassing the onboard TE8022 so that I can have the upsampling and de-jitter...

Here's the response from Kingwa. Basically his answers correspond to what is already posted on the DI-V2 page, but it's interesting to note that according to Kingwa, the DI-DSP with the Reference 10 is the better option for connection. He didn't provide any comments about sound quality though...

Audio-Gd just released the new DI with the Tnor8802 chip, with 3 different models to choose from. http://audio-gd.com/Pro/dac/DIv2/DIv2EN.htm   Have just emailed him asking what's the difference between the standard version vs DI version.

Interesting to note that Audio-Gd introduced a new USB chip, the TE8802 for their latest product line and upgrade capability for certain products.    Perhaps it's just a matter of time before we will see a Digital Interface MKII or something similar for Audio-Gd to compete wiith the big boys....

I think the BA Mod with the Earth HDAM has finally settled after almost 3 weeks of burn-in. The sparkle and treble have return after disappearing for about a couple of days. The modded Earth in the FUN seems a totally different beast now. No longer does it sound clinical with a touch of...

This is rather odd. The BA Mod I did with the Earth Module with the K42 on the FUN started sounding rather odd. There is distinct loss of air and sparkle in the treble. Sounds very dull. Its been almost 250 hours burning in. Is this normal for such a drastic change in the sonics? Reminds me of...

Quote: Hi Mad Max,   What is the capacitor that you used for the power supply bypass in the picture? It looks like a Vishay-Roderstein MKP1837 1uf. Is that the best for th4627-1B?

Quote: Yes, Peete, I decided to leave the GND wire attached. No doubt the K42 will take a long time to burn in but I can already hear the sound opening up. With the GND wire attached, I no longer hear the pinched quality that was there earlier. THe sund has opened up and the bass is now...

Quote: Peete,   I did the mod as you suggested with the Earth module with the K42 PIO. Just been burning in for the past 10 hours. Early impressions shows a deeper soundstage and a bit airier in the highs. Details are much clearer than before. I had the ground wire attached in the...

Quote: Try switching off the DI and unplugged everything, USB cable and Coaxial cable. It happened to me too after switching to the new hex inverter. When power back on again, it became centered again. Weird but maybe sometimes when left powered up too long, the channel imbalances...

Quote: uelover,   could it be that while inserting the chip, some of the pins didn't go into the slot? I had the same issue until I check and sure enough, the pins didn't go into the sockets. The pins themselves are so thin that sometimes they may get bend out of place.  

Quote:   After extensive listening, I prefer the Tentlabs clock when upsampling in my system. It sounded a bit more organic and better separation and soundstage. There's a slight move back in the presentation and voices tend to be a bit more separated from the instruments. Not to say...
