Could the USB port of UPL provide enough power for wireless flash drives such as this 32GB one for $18?

We could always add our own USB hub if external power were necessary, though UPL itself might / might not be able to read the files off those somewhat "special" drives.

 

If everything were going as planned while the USB stick could still be accessed locally by UPL and remotely by another computer simultaneously, it could be worth a try to write some relatively simple scripts to manipulate the playlist on the fly.

 

Of course we still need to figure out how slow it REALLY is

The device is no speed demon: I uploaded a 100MB file over my domestic 802.11ac router and it took 3.5 minutes to finish the transfer.

 

That might seem to be a bummer but thankfully 44.1/16 *.wav files ain't THAT large to begin with. Even if replacing files on the fly weren't feasible, hopefully we could at least read stuff like filename (i.e. title of each track) / folder.jpg (i.e. album art) remotely.

 

Does it sound like something that's doable?

OK. I can say that I really do like this DAC. Very UltraAnalog sound per early 90s. Attacks are just slightly rounded, but good bass textures and definition. None of that one note PCM1704 bass. As I indicated before, resolution exceeded expectations. Better than Airist RDAC and possibly Modi MB.

It's been exactly two months since John and Gordon mentioned their D/A96TF with Fractal converters. Did anyone get a chance to ask them what to expect in 2020?

 

UPL24E certainly sounded like a winner to me, they're definitely working hard to develop apps for multiple operating systems

USBridge Sig with Shanti could be an ideal combo for $400 then

To lower the noise of the USB, we had to lower noise on EACH rail. In total, USBridge Sig uses more than 30 LDOs. Even the SD card power rail has a dedicated LDO. There are zero switching elements on board.

  • Let's say we're running VNC or Remote Desktop Connection on a desktop / laptop computer after the driver of UPL96ETF is installed, is the user interface of UPL_remote software responding well to the touchscreen when we're accessing that computer remotely via a smartphone / tablet with iOS or Android?

  • Is UPL_remote software able to display ID3v2.3.0 tags in Asian languages correctly instead of showing gibberish characters?

I created 5 copies of the same *.wav file with 1 second of silence, then added the corresponding Album / Artist / Title tags accordingly before uploading those *.wav files here

ID3v2.3.0 tags with Japanese / Chinese characters on the left, and then filenames on the right.

 

I verified all of them with MediaInfo as well as MPC-HC, everything looked perfectly fine.

By the way, does anyone know whether it is possible to feed the U96ETL with I2S using some conversion? Then I could find out how the SDTrans sounds with the ECdesigns combo vs the Terminator.

 

While I do have SDTrans384 myself, it's much better to ask @gstew and @pm325 about the I2C / I2S compatibility of ReceiverPi with Raspberry Pi / Allo USBridge Sig

This is unfortunately not possible despite the bidirectional USB interface of the MC-3+USB. The reason is that both the MC-3+USB and the DAC are USB slave devices expecting a USB master (i.e. a computer) on the other end of the line.

 

Recording should be supported (i.e. saving to a specific file that's stored on local drive) by Mutec while we're talking about SDTrans384 → Mutec → Computer → U192ETL in real time here.

 

What kinda software could actually accomplish that particular task mentioned above?

Did anyone actually own any USB audio devices that don't require a computer / mobile device of some sort to operate? In other words, the communications between the USB hosts (i.e. computers) and the USB slaves (i.e. USB audio devices) should rely on the device driver to work properly.

FYI - Greg found that Allo USBridge Sig as well as properly modified + powered RPi 2B could yield excellent results, about the same league as SDTrans384 with a decent (but not his best) PSU

I guess that maybe SDTrans384 could still be fed to I2S input of ReceiverPi while connecting U192ETL to USBridge Sig then?

I can say the sound quality improvement is something else -- I don't want to go into hyperbole but it's a big jump with dramatic improvement in everything. That's after a couple days of burn in, so hopefully further improvement.

 

Total cost for this is roughly $180. Each 8 port injector is $22, each U Green cable is about $5, the 2.1 mm male to male cable is about $8.

 

If we're willing to wait for the slow boat shipping (i.e. free) from China, each 8-port injector would actually cost just under $10

I've got the "big brother" (i.e. D10) of Melco D100 and both of them are USB slave devices, therefore they must be connected to a USB host (i.e. computers / mobile devices / digital audio transports etc.) device first while XMOS XU208 inside U192ETL is also connected to that same device. The whole point really is all about loading USB Mass Storage driver for Melco and USB audio driver for U192ETL respectively.

 

For connecting Blu-ray drives to UPL96ETL via USB, John will have to update its firmware in order to be able to recognize the file system of audio CDs (called CDFS) instead of FAT32 that's found on USB flash drives.

 

Finally it's a completely different story with that upcoming CD transport from Schiit Audio, they're incorporating their own proprietary USB board so that's gonna act more like USB host device on its own

Then we have the new USB board, which we would roll our own implementation into a generic Microchip Pic Part. Up to now, the best choices are XMOS or C-Media (which we now use).

It's definitely Melco D100 as linked below, that USB 3.0 port on the left (USB 3.0 TO DEVICE) is more like USB hub for connecting another USB DAC / DDC such as U192ETL so that both D100 and USB DAC / DDC could talk to the same USB host device simultaneously

11yWPlU.png

 

Once again XMOS U208 inside U192ETL won't work without a specific device driver loaded and therefore Melco D100 by itself couldn't do anything about the device driver part, therefore we still have to connect our computers (e.g. Raspberry Pi etc.) or digital audio transports (i.e. Bryston BDP-1 etc.) to that USB 3.0 port (USB 3.0 TO HOST) right in the middle of Melco D100.

 

That CD transport from Schiit Audio really is a special case because they're spending a fairly long time to work on the USB host part.

The question remains: was there something seriously good in @Huubster's setup with the U192 + Zen Mini combination? Or was something seriously wrong with the UPL? It would be nice to get some more data points.

 

We've gotta find out if there were any confounding factors, were both U192ETL and UPL96ETL connected to Zen Mini with the same USB cable as well as the same USB port? (i.e. USB signal integrity / the source of power must be identical.)

 

If all of the above were true, was Innuos Zen Mini itself constantly powered by SR4 during the comparison between U192ETL and UPL96ETL? Was SR4 itself plugged into the same outlet / socket with the same AC power cable?

 

AC power would tend to perform MUCH better in the middle of the night, were both U192ETL and UPL96ETL tested around the same time slot?

 

The crystal / clock inside each unit would take quite a bit of time to stabilize, were both U192ETL and UPL96ETL powered on for at least several hours before the comparison was conducted?

Perhaps in the first tests the U192 had not "warmed up" yet, or perhaps the surrounding high noise devices created some interferences that the UPL (which does not receive music data from the "control" computer) was less sensitive to ?
