Hi,

I thought the ESS9018 can do 32/384 through IIS. I read a lot of the Chinese ES9018 DAC can support 32/384.

Can the BIIISe support 32/384 ? or these Chinese DAC are not truely supporting 32/384 ?

Alan

The short answer: yes.

News to me. Seems very unlikely IMHO.

USB is developed by third parties, whereas, Thunderbolt is developed by Intel. What I meant was USB 2 and USB 3 will be dead soon if we listen to extreme hi res music. Sorry for my English and cause the confusion.

A couple of months ago, I manage to get some extreme hi res demo files such as, 2L's DXD, DSD and Wav 192/64 (unknown source, my friend unwilling to disclose). When I plugged my external hdd into my heavily mod PC through USB 2 and USB 3, the DSD file and Wav tracks suffered shuttle and I heard some noise. At first, I thought is was caused by my PC but after I check and recheck, I discovered the transfer rate for DSD file is about 48 Mbps which very high and even higher than the blu ray movies. I had to uncheck the playback from ram and increase the latency and buffering, only then the shuttle and noise disappeared but the sound quality was not impressive.

Only when I played the files through my sata 3 WD caviar black internal hdd with the original setting (playback from ram and minimize buffering and latency), it showed the strength of DSD and 192/64 wav file. Like the extreme hi res files had improved the efficiency of my Sim Moon amp, Sonus Faber speakers, Cardass cables, Furutech Flux cables and Furutech Daytona 303 power conditioner combinations. My system had created a holographic imaging when playing with 192/64 wav file and DSD file. As though, the Eagles band and Norah Jones were playing and singing in front of me. I was impressed!

With the launching of Thunderbolt Ver. 3 and increasing capacity of hdd, I can foresee that more and more extreme hi res file will be available in the future market.

I never dream of getting 192/24 wav file when Chesky Records released 192/24 mastered CD years ago, needless to talk about the DSD file. Today, we can even purchase and download DSD file from acousticsounds.com and there are total 358 DSD albums for us to select. You will be surprise here, in our place, a lot of us are playing hi res and DSD file.

Below is the extract from computeraudiophile.com recent post "I was handed an iPad that contained a "real" music collection rather than Scottish nose whistle recorded at 33 bit / 384 kHz." and the link is provided for your reference.

In my opinion, whenever there is good product there will be demand. May be we will be able to purchase and download 33 bit / 384 kHz file in the future, who knows.

Appreciate your recommendation, Kesgreen, I am aware of the products. Just that I am still exploring whether the combination suit my system. Furthermore, I am expecting my BIIISe and IVY III arrive by next week.

Yes, I have received my BIIISe and IVY III kits and I will order the aluminum casing tomorrow. Exciting!

Thanks for your advice, Barrows. As a music lover, I love all kinds of music. Actually, I have downloaded the DXD demo track and tested with my system, not bad. I might want to download more after I have completed the BIIISe project.

Do you like the HQplayer's sound? I have tried the trial version, is good and I prefer the HQplayer than the Jriver 19 and Foobar. However, HQplayer's setting is pretty tricky.

After I have completed my BIISe project I might want the following set up: -

Sonore + BIIISe and IVY + HQplayer

Any comment on my propose set up?


Regards

If you are using a Placid to power the Buffalo, you may need to increase the shunt current. The ESS chip draws more power as sampling rates increase.

Hi Brian, I discovered the problem was generated by 1.2V Trident:

- Trident 1.2V works until 192 Khz outputing 1.15V. For larger frequencies the voltage falled to approx. 0.8V.
- Therefore I had to increase by 20mA the shunt current (decreasing R4) that now is approx. 148mA.
- While playing now 384 Khz the Vout decrease to 1.11V, still not within ES datasheet tolerance (1.2V +- 5%), but working apparently without clicks and pops.
- I will soon increase a bit the Vout by increasing R3 on the Trident (1.5KOhm presently, increase to 1.58KOhm)

- The Vout of the 2 x 3.3V Tridents remains stable at 3.24V, within datasheet tolerances (3.3V +- 5%).

- No success instead for DSD 512: the music comes out with a very loud noise;
- With DSD 256 the situation is better but I experience clicks and pops.
- DSD 64 and DSD 128 are played perfectly.

Any other suggestion?

Thanks,
Best regards,
Andrea

Dear Brian,
Unfortunately I have to say I don't think with hindsight:

I did all possible tests AFA my knowledge allows: my Placid didn't make any change in voltage (stable at 5.24 volts) both during switching and while playing different sample rates up to 384 Khz.

I set the current even at 700mA... but the issue with the 1.2v Trident remained.

Furthermore I carefully monitored the remaining shunted current on the Placid, and it never went below 60mA even at the worst condition (playing 384 Khz).

As said I solved the problem increasing by 20mA the 1.2V Trident current... [original SMD values R3=1.5K, R4=10, R8=100K]

The 512 and 256 DSD playback issues still remains... Nothing to be worried about, considering there are no music native in this format at present :)

Thanks for your advices,
Andrea
