Does anyone has checked the sound quality of the TI PCM1738 vs. Analog Devices AD1853? I'm looking for a 24/192 DAC with software control and a current output (i.e. no internal I/V stage). What about NPC SM5865C?
I am designing a DAC around SM5847/SM5865 chipset - see this thread. The boards will go into production very soon. I have high hopes for this chip...
Hi Andrei,
thankX a lot of the link, nice DAC. I hope finishing my DAC in some days. Currently I've implemented TIs PCM 1738 but some other DACs seems also very interesting. I'm not sure which DACs sound better in some postings I read that the new TI DACs sound very bad, but I had not found any similar to the ADs. I'd prefer the AD 1853 and TI PCM 1738 DACs over the PCM 1792 and AD 1955 because of their lower output currents witch are easier to drive from the I/V stage.
My I/V stage is a discrete, single I/V-filter-buffer stage, with second order low pass filter, which has only 4 components in the signal path, very close to that what is discussed with passve I/V "conversion" with triode output stage, but the I/V-filter-buffer stage in my DAC is active. I think, KWAK has a similar Idee too.
I'll post the schematic when it's finished, but currently I'm looking for a very good DAC. I know the PCM1704, on the other side the bitstream converter are not bad in itself. Unfortuanately Norbert Bayer from http://www.diyaudio.de has not finished his modular DAC, this could be very helpful.

The AD1853 is very soft and warm in its sound structure. It is almost like listening to an LP, so it lacks the last bit of sharp teeth if you are checking out the newest Metallica. However for acoustic stuff and piano singles it is simply the best DAC chip around.
I would also suggest taking a look at Cirrus Logic or AKM, both these are lightyears ahead of NPC with regards to clarityty, resolution and ambience.

That's what I'm looking for. More a warm, smooth and analog sound than that what I get from digital audio. I do not think that typical for digital sound.
On the other side I like Metallica 😉 I hera it on a Linn, not bad for the moment...
Did anyone compared the sound of the TI converters vs. the Analog ones? What are the differences in sound quality? I think I need a good starting point when optimising my DAC. Replacing the converter later will result in much more difficulties than in this early stage. Unfortunately the AD 1853 has no slow roll of with only a few taps in the digital filter as the PCM 1738 has.

AD vs TI
I prefer AD mostly because they are easyer to get here. And more, TI are more consumer-oriented /low-cost oriented/ than AD. From analog view, AD make better OPAMPS /and more expensive, too 😉)/ They are some higher-end industry - my favourites are AD8620/10, AD811, AD797 etc. From TI, the favoutrite is OPA2134, much cheaper.
Dont bother about more output current - I do not see the problem here. Just more headroom 😉)
Else AD1853 and AD1955 are equivalent, except the extra features of the 1955 and the little more headroom / DR
I'll use the 1955 soon, I have some of them and do not want them just to be in my stock 😉
Regards
