iFi,

 

cheers for the FAST replies today, and the hints!

 

I'll await the OTW #3 and follow on answers in the coming weeks.

 

now to figure out when/how to pre-order this genius device...   ;)

Dear ifi—

 

Thanks for your responses, but I'm still trying to get an answer to the following question:

 

I have both Audirvana and JRiver for OSX. Can these pieces of software play "direct DSD," like ASIO on Windows, or only DoP? 

 

Thanks,

Alex

but you mention , minimum is the filter . and standard is down .

im confused . hahaha !

 

Hi,

 

Here you go:

 

Minimum

Standard

 

O

 

Filter

 

Actually means

UP = Minimum

Down = Standard

 

Filter at the bottom = this is the filter switch.

 

Hope this clarifies.

Hi,

 

For Audirvana+, you are best contacting Damien Plisson. 

au.damien78@gmail.com

 

For JRMC, you are best contacting Jim Hillegass.

jimh@jriver.com

 

We don't wish to comment out of turn on another manufacturer's product.

 

Also, updates and changes come through all the time. They can tell you what they can/cant do and what is coming in the pipeline.

 

Thanks.

Thanks, but this still doesn't answer my question. So let me pose it another way. Is there any software for OSX that enables "direct" DSD playback (as opposed to over DoP) with the iDSD Nano? A simple answer would be much appreciated :)

Hi,

 

Software is in constant flux, we just make the hardware! :blink:

 

Any OSX software that supports ASIO will work. ASIO is mainly used for pro audio, so most OSX software to support it will be aimed at recording/editing audio.

 

Cubase 7 with patch or later supports ASIO (2.2) on OSX.

 

Cubase is made by Steinberg (the people behind ASIO).

 

Ta.

Yupp you definately clarified my doubts there ! ^^ thanks !

Haha this thread is becoming a GENUISE Bar for iFi-Team xD everyone comes here and ask question. But I/we do like the quick responds! Also enjoy reading it xD

I'm planning to get a DAC eventually, so I'm pretty excited to see how this stacks up against the Uber Bifrost. (about the same price, $500 and $519, I believe)

If you wanted to try another site for some natively recorded DSD256 test stereo files after the DSD256 firmware update try;

 

https://justlisten.nativedsd.com/albums/just-listen-1-compilation

 

 A few are natively recorded Classical Guitar done at DSD256.

And this Japanese website for DSD 256 natively recorded piano concertos.

You can go direct to their website but you have to scroll down and find each individual recording:

It's Sunday and if you would like a cat nap, you may wish to have a read of this. :smile:

 

Technical Notes (3)

 

Cherry-Picking the Chipset: Going to the nth degree

 

Selecting the ideal chipset for a DAC is not an easy task for any audio manufacturer.

 

We are faced with two choices:

 

Option 1 - select a chipset that is well-known. Sonically very good, newer and with high customer awareness.

Option 2 - select a chipset that we think sounds most gratifying but customers are familiar with is a risk (may be more expensive, existent, etc).

 

For iFi, since the AMR days we have and will always continue to choose option 2. This somewhat goes against convention and is riskier but we truly believe the sonic results are worth it.

 

Back in 2000, when we started the development of the flagship CD-77 (USD11,400), we implemented extra steps to extract an additional ~30% more sonic performance from the legendary Philips TDA1541A DAC chipset. We brought to market undocumented features and it was and still is a fully-maxed out sonic performer.

 

The pictures below give you some idea of the length we went to.

 

1. Audiophile Level 

 

 

2. Datasheet Implementation Level

 

 

3. Advanced Level

 

 

4. AMR/iFi Level

 

The TDA1541A has a worldwide following and is justified in our opinion for a whole host of reasons. We were not the only people to use this chipset but we researched down to the silicon-die level, to extract the most out of the chipset. Able to confirm to customers that the CD-77 not only has this remarkable chipset but it has been implemented with a dash of “factor X” – is the equivalent of getting a super car and then re-mapping the ECU and uprating the drivetrain. Neat.

 

Similarly, for the upcoming micro iDSD, the DAC we picked is a direct descendant of the renowned DSD chip, the DSD1700 (Just like in the PCM world, the Philips TDA1541A is legendary, especially in Japan). 

 

The platform we chose for the micro iDSD (and the nano and rest of iDSD range) was the Burr-Brown. Why? Because it is one of the few chipsets that handles DSD and PCM without internal conversion. It keeps things unchanged and whether your music file is DSD or PCM, the whole chain remains as close to original.

 

In the iDSD micro we go to great length to provide that. Finding a readily available DAC Chip that treats both DSD and PCM fairly was a challenge. Manufacturers generally are quite mum about what goes on inside their chipsets, so often you have to actually test the part in detail to figure out what is really going on.

The DAC Chip we use in the iDSD nano offers a rather unusual way to handle things. It uses a 6-Bit Multi-bit DAC for the upper 6-Bits of PCM Audio and delivers the warmth and slam Burr Brown Multi-bit DAC’s are so famous for. Any bits below this are converted with a low-order 256 Speed Delta Sigma modulator (in effect DSD256) giving PCM playback the smoothness Delta Sigma DAC’s and DSD are famed for.

 

The Burr-Brown True Native DSD/PCM chipset – handling PCM and DSD natively

 

 

 

When playing DSD the same Delta Sigma Modulator is used as directly to convert the DSD Bitstream to analog. Of course, there is no digital filtering available for DSD and no digital volume control, so we have to add these features in the analogue domain, where they arguably belong.

 

Conclusion

So if you have a recording that was made in DSD, you can hear it natively on the micro iDSD.

 

So if you have a recording that was made in PCM, you can hear it natively on the micro iDSD.

 

To be cont’d. Part 4: DSD and PCM in more detail.

thanks for the update...and for keeping DSD and PCM native without any conversion. there are people around these parts who SWEAR that converting PCM to DSD sounds better, that the DSD FORMAT itself "just sounds better." i think they're full of it, but who can argue with crazies? nice to know that iFi goes to great lengths to keep these formats as-is, without conversion to one or the other.

its the same with some recent DAP releases. people go crazy about DSD playback being implemented via firmware updates. most of the time its simply a DSD to PCM conversion because the chipset cant handle DSD natively. after reading Thorsten's article about the two algorithms being completely different I don't see any benefit in that. the only factor to have such a feature would be if you have a large DSD library and you can still listen to it over your DAP this way, even with an undesired conversion, otherwise don't bother...

People hear differences in all kinds of things, from wire to capacitors, resistors, pots, DAC chips etc. It doesnt make them "crazies".
