The EVGA NU Audio Card supports native DSD playback up to x256, currently. No pops at all when converting everything to DSD256.FAQ 59748 – How do I configure the NU Audio Card for ASIO or to play DSD or. I only have a mild pop sometimes at the first playback after power up. With foobar2000 it's less frequent but still random and annoying I ended up converting everything to DSD256 to minimize. It also depends on what is the filter setup for the DAC at the different rates you may want to go higher with some DACs, if for some reason you find the crossover frequency too low.Īudirvana with the Topping D50s doesn't really work well, the pops at playback start and format change are frequent and very annoying. My Topping D50s is at its best with DSD256, slightly worse at DSD128 and DSD512. Note that Audirvana and HQP have a slightly better output, on the ESS DAC, but they need 3 dB headroom which needs to be compensated also when playing PCM.Ībout the best rate to output it depends on the DAC testing with MTA is recommended. Here's a comparison on my 5950X converting to DSD256:ĭSD Processor, supposedly using 5th order filters: 15-30WĪudirvana Studio r8rain 5th order: 50-60WĪudirvana Studio r8rain 8th order: 50-100W If you don't have a powerful system, it can fail or create distortions. It's not CPU intensive at all, it's very latency dependent. Yes the DSD Processor is old but it works pretty well only exception is conversion to DSD512 which is bugged and fails randomly. I think that's one of the many reasons why people have so much of a different experience with DSD. So to Increase the cutoff frequency you have to upsample to a higher DSD rate. Like the topping E70V has a low cutoff frequency for DSD. The cut-off frequency is a issue as well with some DACs. Otherwise this is pretty much just wasting resources.īut the D300 outputs only 3.7 volt In DSD and so you need to raise the volume to be able to really compare it to pcm. But the SDM that you apply has to be better (or more to your liking) than what the chip does. The SMSL D300 has the ability to bypass the SDM. Same goes for the high pcm and DSD rates the new AKM chips support. ![]() The Topping E70 velvet for example doesn't support sdm bypass or DSD direct mode. The manufacturer has to implement that stuff. Or that they are equally nice to listen for you.Īnother issue is even if a chip supports some cool stuff like SDM bypass, volume leveling between pcm and DSD etc. And the DSD stream goes through the same SDM.Įven if you use HQPLAYER with some crazy upsampling it will still go through that SDM.īut it explains why you might prefer PCM and DSD on one or another chip. With DSD it's really a wonky thing with DAC manufacturers and chip manufacturers.ĮSS does some stuff to DSD so it has the same volume as PCM. Luckily I returned it and now with the ESS DAC the PCM and DSD output are equally good for me.īut this doesn't mean that since I don't need it nobody else should and they are silly for doing what they want with their stuff, right? That's why I ended up using it converting always PCM to DSD that's something that was done right. On top I found out that I don't like at all the "musicality" of the AKM PCM decoding while PCM converted to DSD was much better. It means anything above 10 kHz is attenuated, I can distinctly hear the difference and I'm almost 50yo. You can check the AKM4493S datasheet yourself and see that the frequency cutoff it's at 8 kHz. This means that there's a massive audibly different conversion of PCM to analog up to 48 kHz compared to almost anything else (which is usually configured as default with a Sharp Roll-off filter or anyway not one that bad). That DAC is unfortunately configured by SMSL with the Super Slow Roll-off filter and can't be changed. Search function of the forum is your friend. I don't know how many DACs are out there which are audibly different converting PCM to DSD but I gave you one and that should be enough. ![]() It's not silly number-chasing, there are many reasons why people would like to convert PCM to DSD.
