post #1201 of 2425

I personaly use JRiver 19 for PC to play music on my desktop and I use JRemote on my iPad to stream the same music library when play music around the house wireless. But even JRemote is imited to playing 24bit/96khz, I have to downsample my DSD and 192khz PCM files.

 

Is there any program that can stream DSD 64, 128... and Super High Rez files up to 384khz on the iPad, iPhone or Android Phone wireless? I am not aware of such software. The Onkyo Player can play these files of course but then you need to have them stored on the device (instead of streaming). That really is the greatest issue so far, mobile devices are limited by storage space to be true high end players (or you can only have some albums) and the wireless options are simply not there to stream all types of High Res files. There is lots to be done, lots....

select iDSD Micro or iDSD Mini

Conditions

1. In a small room with no power conditioning and with noisy mains.

2. Funds are sufficient for iDSD Mini, AMR CD-77, AMR DP-777,....., but room is small - don't want to have too many big boxes (space already taken by 4 large monoblocks)

3. Setup is fully balanced with xlr cables, except for iDSD Nano

Current setup is Squeezebox Touch > iDSD Nano > Audiolab 8200cdq > Balanced Active Crossover (no rca allowed) -> 4 Balanced Monoblocks

iDSD Nano is now 100% volume, Audiolab acting as preamp as well as a rca to xlr convertor as well as cd transport

Will there be a cd transport from iFi Audio ? smily_headphones1.gif

Thank you for reading my long post.

 

Hi,

 

Not a long post but you just got to speak to Stereo Electronics and borrow a micro iDSD and try it out.

 

You can try the micro iDSD in pre-amp mode and direct and see how it fares against the more expensive equipment in your setup.

 

You have some serious amplification there downstream from the nano iDSD! Like we said, these little guys can play in big rigs.

 

Absolutely not an issue.

 

The CD-777 is already a CD transport!

 

Thanks.

Can you suggest me someone I can borrow an iDSD micro from in Rome? And/or even a nano to compare them.
I don't see other chances of trying before buying it.
Thanks

As anyone a suggestion where to buy in the Netherlands? Because of all the good information there is no doubt for me to order a Micro iDSD :wink_face:

Hi,

 

Best you contact Pro Audio Italia and wait to see when they have a demo machine after the "Octa-Adopter" shipment.

 

The "Octa-Adopter" units are for end customers only, they are just too limited and unique.

 

The micro is easy to ship (being portable comes in handy) so these units making the rounds throughout Italy is not a big deal.

 

Sorry but the only option is to get a ticket and wait.

Hi Mr Prins and TechnoBear,

 

Not all iFI dealers will have the Octa-Adopter units. Not enough to go around.

 

Only Hifidelity.nl and Art's Excellence have the exclusive on the "Octa-Adopter" units.

 

So we suggest try these two retailers.

 

Thanks.

The connectivity and form factor of the Mini seems to be better suited towards those who have spent the $$$$ on boutique USB cables. I personally don't own any boutique USB cables, but if I did, I surely wouldn't bring one with me while I'm out and about. These people were probably going to get a short 6" boutique cable made anyway for portable use, and I'm pretty sure their go-to cable maker would have no trouble terminating it in an A-type USB.


 

Also, I doubt many people have short B-type USB cables for portable use because most portable DACs out today don't use the B-type input anyway (except the Nano). And don't for one second lie through your teeth that you were going to lug around your 3 meter $1000 boutique USB cable with you for your morning commute on the subway.


 

Personally, I don't see why you would want to lug around the Micro when the Nano is half its size and also provides the magical B-type USB input that everyone seems to want. Yeah, the Nano is not as "hi-fi" as the Micro, but seriously save the diminishing returns game for your home system. When I'm on-the-go, my main priority is not having to lug around a bag of bricks.


 


 

TL;DR: Are you going to use the Micro for its intended purpose of 50:50, portable:home? No? Wait for the iDSD Mini; you can use your $5000+ cryo infused, alien technology B-type USB cable on that.


 

The Mini:


 


this minidsd maybe the right choice for me. considering the normal usb input. just hope this mini released this year

Now, I understand that the jitter reduction tech is excellent.  But added noise is never a good thing, in my opinion.  After all, the performance of the jitter reduction system is only as good as its clock.  And any extra noise can cause extra jitter in the master clock itself.

Hi,

 

The adapter is very short, minimal impact, hence for it to pick up RFI is really negligible.

 

Then right at the end of the line, we have the iPurifier to clean it all up.

 

We previously outlined that the GMT and Jitterless are right at the end to address any jitter issues that occur upstream. If you get a chance, take a peek at the GMT+Jitterless technical notes we wrote before.

 

Normal implementation, yes, there would be one clock but we dont just have a clock in there. It is a whole module and among other things, it tracks frequency changes as the clocks change temperature, not just jitter which everyone knows about.

 

There is a full article in the AMR DP-777 technical papers section. If you look at the micro iDSD specs, the jitter measured using the AP2 we have is at the vanishing point. So the micro iDSD can measure against the best out there and not break a sweat.

Hi,

 

Thank you for the reply. I have no doubts that the micro iDSD will be great and of course greater than the nano iDSD.

I will be direct and ask 2 questions:

 

1. Which is better in an environment with noisy mains - micro iDSD or mini iDSD not the nano iDSD?

2. Is iFi Audio planing to release another CD transport that is clocked slave to the mini iDSD? - Then I can offload my Audiolab :)

Hi,

 

1. Run either on battery - why put up with bad mains? But if you run off USB power, then micro iDSD is better because of attention to power supply section.

 

2. Nope. But if you wish to use SPDIF via the CDT, then keep the AudioLab. You may get a Touchscreen PC with a disk drive or similar and play through USB? The GMT+ZeroJitter tries to make sonics as impervious to the USB connection as possible. So break-free of the audiophile need for synch'd locks etc...

 

GMT+Zero Jitter also kills SPDIF input Jitter via the coaxial.

 

All the tech notes largely illustrate that what we do inside makes what happens upstream and downstream far less mission critical.

 

 

Thorsten just asked us to put this up for you as it is hot off the AP2.

 

This sexy jitter test is done a la "Stereophile" (so you can compare with other mega buck DACs in the published articles to see how the micro iDSD stacks up).

 

Jitter tests style, 24Bit/48KHz:

 

 

It is the SPDIF input of the iDSD micro with a signal that had 50nS (50,000pS) of 400Hz squarewave jitter APPLIED (read: forced fed jitter that has been artificially created by the AP2's "Generate jitter" function). 

 

We originally tried to generate this trace directly from the AP2 in loop-back. But at 50nS/400Hz square-wave jitter the AP2 could no longer lock onto the SPDIF signal. So we had to "hack" iDSD micro to disable ZJ! :p

 

- the top traces (Red+Green) is GMT+ZJ Jitter OFF. The micro iDSD is just like other DACs.

 

- the lower traces (Cyan+Yellow) are with GMT+ZJ enabled. It is basically identical to SPDIF in with NO jitter added and to the trace from USB. So you see, the iDSD micro does to jitter what Jason Bourne does to a trained assassin. 

 

So no need to link the clock back. Any SPDIF source that is Bit-Perfect (not all CDP SPDIF outputs and really cheap DVD players are), will do. We take care to remove the jitter, be it via SPDIF or USB.

 

Summary

i. So what we did was to have AP2 simulate a SPDIF source so crappy, the AP2 itself could not lock onto the signal.

 

ii. The iDSD micro not only locked onto the signal but also killed all the 50,000pS jitter from the source.

 

iii. Top traces show that so much jitter produces noise with 400Hz (jitter frequency related) peaks every 400Hz and the noise is huge, we are talking around -40dB,it makes old Cassette tape distinctly noise-free.

 

So please go-ahead and make our day and put the micro iDSD in a "big, big rig." :wink_face:

 

As the Americans say, "bring it on."

iFi gurus,

Thanks for your continued explanations of the engineering, built in iPurifier is a welcome advancement in the world of portable DACs!
Simpler question:
What is the length of the iFi blue USB male A to USB female A that can be used at the desktop PC (without needing adapter).
Cheers.

Thank you for your answer for qn2, but I think you probably read too quickly for qn1. I am comparing iFi iDSD Mini (not yet released) with iFi  iDSD Micro (released in mid July 2014) :-)

Does the iFi iDSD Mini also come with a battery supply ?

 

I hope I do not come across as rude, just a consumer trying to find out more about iFi iDSD Mini (You have got competition within your products)
