It seems to work extremely well in the Reference 1/7 DACs. Back when the DAC8 was Audio-gd's top of the line DAC, they added the DSP1 module to it and it became the Reference 1 which was the new and improved model. I can't imagine that the same types of improvements wouldn't be realized by the DAC19.

Besides, the jitter reduction, the new DSP-1 has a lot other functions which supposedly makes it better than the older df1704. In theory, its programmable functions and raw power would enable the designer to use more accurate one pass oversampling filters. Anyway, I would also find curious that Kingwa would use exclusively the DSP-1 on his flagship DACs if it didn't provide a big improvement over the older chips DF1704 and PMD100.

Anyway, I did some research and I wasn't able to find direct comparisons of the 2 filters ... So it is just an educated guess for now. Hopefully, some new DAC19 owners will do the A/B tests...

DSP-1 vs. DF1704

Since everybody seems curious about how the 2 digital filters, I asked Kingwa and here is his (long) answer :
The DSP1 is applied high speed FPGA , I have asked a lot technician how about FPGA and moto DSP56000, they agree the FPGA is better for digital audio than the Moto DSP56000 line up. The FPGA has long life and high speed , and the configure is better than DSP56000 in digital audio system.
The DSP1 has very low phase change. And our DAC applied 6DB/oct analogy filter, (a lot other brand all use 12DB/oct or 18DB/oct filter), 6DB/OCT has low phase distortion than 12DB.
The DF1704 I have applied a lot years, I find the slow roll off sound more neutral and more detail the sharp roll off. And slow roll off has lower phase distortion.
The DSP1 compare to DF1704, just like our RE1 and the DAC9MK3, they has same configure but only different of the DSP1 and DF1704. The sound is a bit different. The DF1704 is a little bright side, the DSP1 is neutral, the PMD100 is a little warm side. But the DSP is a bit more detail and dynamic and better extend on low and high.
There was around 30 owners use our DAC8LE upgrade to DSP1 and find better sense, this is a direct compare.
Kingwa Having tried both the PMD100 and DF1704, I agree with with Kingwa's description of the PMD100 being slightly on the warm side and the DF1704 being slightly on the bright side.
So it seems that the DSP-1 is "more neutral", more detailed, more dynamic and with better extension at the highs and lows... Very tempting! I am probably going to have to upgrade to the dac19-DSP at some point

Don't know what the heck that whole chunk of text is about but it sure sounds good

I'll probably be getting a dac19 dsp instead of waiting for the upcoming 'entry level' balanced dac. It's a little more than what i'm willing to pay, although i'm curious how well it will sound given my balanced rig

DAC19 DSP arrived today

Excellent customer services from Kingwa again, and took only 3 days to ship this time!

Just connected via USB just now until my hiFace arrives, but instantly in love with the huge amount of bass, especially listening to dubstep/drum & bass.

Very impressed

Thats my thinking as well and is why I ordered the DSP version. I've had it about 3 weeks now and am very impressed with the sound and build quality. Of course I haven't heard the df1704 version so can't comment if it is indeed better, but would think Kingwa would use the better sounding components in his top of the line units.

Anyone know if something's up at audio gd? They haven't replied my mail for 3 days now, wonder if anything's wrong, especially when kingwa's known for his speedy replies. hmmm

Maybe you could try sending another e-mail (he might have missed the first one). I got a reply from him yesterday, so I wouldn' worry much about anything being wrong

If you sent him 3 emails, it is strange that he didn't answer. By the way did you get the automatic reply messages?

Sure did. I double checked that the email i sent was to the right address too. Not sure what to do now, bug him with more mails?

I'm right on the verge of ordering a DAC19 DSP and this delay has killed some of the excitement

did anyone asked/get an invoice for any product from audio-gd ? I need an invoice as proof for customs so they can apply the taxes. I don't want to bother kingwa with an email.

the french dealer has the wrong pictures of audio-gd 19 dsp dac on their website.

I did something similar, asked if I could review one of his products either free of charge or at a discount, got no reply.

Kingwa doesn't send invoices. I've never received one. He certainly should though so people have a record of their purchase.

Actually I asked him for the invoice when purchased the Roc and I got it.
