DAC

 

1. this layout needs 5 LPS,  any one box solution suggestion? Otherwise 5 power cords need to spend lot of money.

 

2. is the voltage fighure correct?

 

thank you very much.

Welcome aboard the Ultra USB train!

 

The Startech LEX needs 5VDC not 24VDC.  That makes it much easier to find a LPS.

 

Here is what I use:

PC Seasonic Fanless High PSRR SMPS.  This currently powers the MB/CPU and the one SATA SSD for the OS.  I have a cable arriving soon to power the SSD from an ext LPS.  So then only the PC will be on the Seasonic.  It has it's own AC line isolation and filter unit.

 

The LEX is powered by a modded TeraDak X1/X2.  This has two DC outputs one set at 5VDC(USB) and one adjustable that I will set at 5VDC also (DC plug) - one now on the LEX the second soon to power the SSD for the OS

The REX is powered by a MEIYAN ultra low noise 24VDC LPS

The Recovery (then to a iPur2 then to the F-1) is powered by a modded TeraDak DC-30W with a DC iPurifer.

 

So just three LPS's needed.

 

All this is spelled out on the opening page of this thread - worth a read.  Post #7 goes into detail on the LPS's.

 

For more info on LPS's I have these three threads that go into detail on which transformer, regulation scheme and caps, etc... are best:

Simplicity:    My previous chain was too long, full of USB gizmos( regen, Intona ), batteries supply, usb wires etc.

 

Music Quality: This is so subjective. I never heard  another head-fier system. My reference point is $100 cd player connected to my DAC. This computer chain it is miles ahead from cd player.

                       Just listening Vangelis-Opera Sauvage, on the song Flamants Roses the harph sound so natural, with bounced sound from left to right, on the circles. Never heard that type of

Synergy: In my case YES

Sorry for my broken english, english it is not my nature language.    

I see - well that makes sense to keep the mR then.

 

Well if you are adverse to USB Gizmos and more wires - this path may not be best for you.  I'm indifferent - SQ is all that matter - aside from having to build a Cyclotron. :wink_face:

 

I just heard back from a friend of mine with a really nice system (Eidilon Diamonds/YG speakers - VAC tube pre and amp - PS Audio Direct Stream DAC - OR5 DDC, etc...)  I will be bringing my entire digital chain there for a weekend of critical listening.  With my DAC and then just the Ultra USB chain feeding his DAC by SPDIF vs the OR5 by i2s.

 

I did this over a year ago - but with the Breeze DU-U8 by SPDIF - it was close but the consensus was the OR5 by i2s was better.  My digital chain has improved so much since then - I'm sure he will be impressed!

Obviously, I'll be sacrificing a lot of storage in making that swap.

In the meantime, the current setup is wonderful.

Thanks again for that, Rob.

Nice Joel!

 

Any suggestions on setting up a virtual RAM disk on one of these devices to run the music files from a buffer?  How's the latency on the IB set-up?

 

Last night did a SLC vs MLC shootout.  Several quiet evening hours going back and forth.  I loaded 6 favorite tracks from different genres and artists - new and old - on each device.  Then built a custom Foobar playlist - with each track in sequential order from each device.  I could then just flip back and forth with my remote.  Same track three different devices.  First time the whole track - then a few more times just the first few minutes.  But this gave me an immediate comparison on the fly.

 

Here are the three devices - ALL plugged into the Startech REX:

 

Apacer MicroSD SLC 256MB   

https://www.digikey.com/product-detail/en/apacer-memory-america/AP-MSD256ISI-1T/1582-1117-ND/5268820

 

ATP Electronics USB Flashdrive SLC 1GB  

https://www.digikey.com/product-detail/en/atp-electronics-inc/AF1GUFNDNC(I)-OEM/AF1GUFNDNC(I)-OEM-ND/5022275

 

PNY USB Flashdrive 256GB (Boy did BB raise the price on these!  I paid $50 each - then got a 20% off discount -so $120 for all Three)

http://www.bestbuy.com/site/pny-turbo-256gb-usb-3-0-flash-drive-black-gray/8052124.p?skuId=8052124&ref=212&loc=1&ksid=e6fca678-2812-43a0-938c-455f0c002001&ksprof_id=8&ksaffcode=pg199136&ksdevice=c&lsft=ref:212,loc:2

 

The SLC's have about 50 hours on them.  What blew me away - they all sounded a bit different.  

 

So here were my preferences:

 

Definitely the standout was the ATP SLC USB, my preferred on 6 of the 6 tracks.  Not huge but definitely better.  Greater bass depth and even greater clarity and detail.

 

On four of those six tracks I slightly preferred the MicroSD SLC - on one it was a sort of draw with the PNY USB. On one track I preferred the PNY over the MicroSD SLC.

 

The Micro SD SLC has a warmer presentation - but a bit of 'hollowness' in the center of the sound stage.

 

The ATP SLC USB had the best dynamics as well.  Now this is on top of really amazing dynamics to begin with.

 

After a few hours of this A/Bing I moved on to just listening to my music off the PNY storage.  I never felt I was missing anything or was let down - it's only in direct comparison did I notice.

 

I sure wish the REX had 5 USB slots instead of 4!  I would like to have a 4GB USB SLC there for just those nights I want to do super critical listening.  

 

I'm considering buying a 4GB SLC for that purpose.  Digikey has these two 4GB SLC USB Flashdrives:

https://www.digikey.com/product-detail/en/atp-electronics-inc/AF4GUFNDNC(I)-OEM/AF4GUFNDNC(I)-OEM-ND/5022309

https://www.digikey.com/product-detail/en/swissbit/SFU24096E3BP2TO-I-DT-121-STD/1052-1180-ND/4805949

 

The ATP is slower but cheaper - $59.46 21MB/s Read speed

The Swissbit is $79.42 32MB/s Read speed.

Rob,

 

I'll try to answer your questions as best I can and best as I understand them.

 

Infinity Blade provides it's own automatic copy function for copying the selected music files to the microSD device.

 

As for virtual RAM, I don't know how to set that up and I'm not sure how the program would process it.

 

Great information on your impressions of the various drives by the way. Thanks for posting that information.

 

While I know this thread is about the USB implementation you've told us all about, I'll just include this one editorial.

 

I've used JRiver, HQPlayer, Amarra, WTFPlay, Squeezebox player, and other players as well. Nothing I've used is as enjoyable as Infinity Blade.

 

There is intensive processing involved. The program itself probably takes about 20 seconds or more to open. And a redbook album can take, depending on your hardware and microSD (the microSD is not required by the way), about a minute to copy over . . . and maybe longer.

 

Still, the result is stunning. You'll have to hear it yourself to appreciate what digital can sound like. Some have forsaken their turntables for this player if that tells you anything.

 

The thread on this player can be found on the JPlay forums. Currently there are almost 4,000 posts.

Thanks I will check that out.  My simple solution with a 4GB USB SLC - would be to just copy over the albums I would listen to that evening.  Then create a custom playlist (takes like 30 seconds in Foobar).  A 4GB would hold 7-8 Redbook albums.

 

Don't think I would want to do the Bughead/Blade player solution.  I do like to 'click' past some tracks with my remote.  Sounds like that latency would be a bit fustrating for me.

 

So far the latency on playing off the REX USB's is quite low.

Hello again rb2013.

I'm glad you made the sound even better. You may not remember my query, but I finally bought a SU-1 Singxer with very good results. Effectively even better than the Yellowtec and more versatile.

In case anyone is interested, I have replaced the SU-1 power supply with a Nano IUSB 3.0 that I already had. Powering both the USB and the motherboard. Also with 5V. I can put photos.
It is likely that with such good opinions about the Startech system and the model of PSA, I also buy it, but it is enough money and I have to think because I do not know if it will be worth it.
I guess in your system is the USB2G4LEXT2 essential?


A final question.

The chassis of your DAC, I suppose you will have a ground connection.
Do not you think that even if you have a galvanically isolated connection to the PC, you still have a source of noise coming from the DAC chassis with the ground?
Assuming the mass of the audio output, share it with the power ground. What do you think about this issue? Have you made any proof?

In my case, this is and can measure continuity with the polymer. And I've thought of powering the DAC with an external DC power source, but the question is whether the DAC will work properly without a grounding in the case chassis.

Thank you and forgive my bad English.


No worries on your English  - mine is horrible (note the frequent edits on my posts!)

 

To your questions - but first on the power supply mod for the SU-1 - yes photos would be great.

 

The Startech is absolutely essential for me - not recommending anyone else buy it.  But it was the overwhelming factor in advancing my system to this exalted level.  keep in mind the PS Audio LR is a different chip and only has one USB port on the backend.  So you lose the opportunity to run USB or MicroSD cards (see my next post regarding the newly arrived SLC USB and MicrSD cards!) - you need those three other open ports for that CRITICAL part of the equation.

 

Great question on the DAC side of things - first my DAC has dual R-Core transformers.  Renowned for PSRR (power supply ripple rejection) - one for the analog side and another for the digital side (brillant!) - no el-cheapo toroidals.

 

But to be on the safe side I use a separate AC line isolator and filter for the DAC - separate from the PC and another for the USB Ultra chain.

 

Remember SPDIF has galvanic isolators built in  - both on the sending end (F-1) and on the recieveing side - this is completely different then the USB galvanic isolation.

 

As I mentioned before the Synergistic Research Element Copper - with active shielding and the new ECT modules (and a Gaelaio MPC shield eneigizer) has really made a significant difference on the SPDIF side - it helped in the image depth and focus nicely.  Prior to that cable I had the very good Audio Sensibility Statement Silver 1.5M digital cable (for sale now in the classifieds).

 

But SR has this other product - insanely expensive - but it's a grounding product that is said to work wonders.

The Synergistic Research 'Grounding Block' - maybe some day I will try one:

http://www.audiostream.com/content/synergistic-research-grounding-block-and-high-definition-ground-cables#16pH3BEdIPExKzhi.97

Thank you for replying so quickly.

 

I think I will be encouraged to buy Startech. Having the U12, Yellowtec and SU-1, I rely on your appreciations.

By the way, any news about the new USB device you talked about? I suppose it will be a combination between a connection between a USB interface and a complete galvanic isolator.

 

In fact, a big problem are the equipment ground, but on the other hand are absolutely necessary for safety and good operation.

 

I at some point try to avoid removing the shielding of the USB output cable from the PC.
I have achieved very good results simply by changing the polarity between phase and neutral of the plugs and it is free. I advise everyone to try it.

In my case, I have a Furman AC-210 E filter and a balanced power supply of Airlink transformers, it's not too expensive. And in the DAC and headphone amplifier with switched power supplies, I am using several DC Purifier with good results.

 

For if it is also of interest, for a mistake I made a short circuit with a DC Purifier and it broke, but I disassembled it and I could repair it. I also have some photo of her inside.

There are several models of virtual lands, some are based on minerals such as tourmaline. I have not tried any of them, but they could be an option.

Here you have the photos of the SU-1 with the Nano IUSB 3.0. Consumption is quite low in both ports.

 

A greeting.

That is awesome - removed the medicore built in supply and replace with iUSB 3.0 Nano - fed by ext LPS.  So the SU-1 just needed a +5 VDC connection?  Or are you running a separate 3.3VDC line?

 

Yes please post the DC iPur board photos.

 

I use a Audience R1p AC line balancer and filter at the wall - before the separate common and differential mode AC line isolators and filters.

post #280 of 402

Thank you. It is also interesting to know what you use for power conditioning.

 

Indeed, it only has a 5V input. The SU-1 board has only two internal connectors, which powers the front LEDs and the 5V input. The 3.3 volts of having them will generate them internally.

 


One of the times I shorted and broke down and since I had nothing to lose, I tried to repair it. It is sealed with epoxy but I could remove it and see the fault. I think what burned was a resistance and I replaced it with a weld. Probe its operation with an oscilloscope and luckily I was able to measure a quantity of noise similar to another that I have well.

 

This device so intuition (you can measure continuity with a polymeter between the output and input) must create as advertising from the manufacturer says, an oscillation out of phase at its output according to input noise. Curiously I have been able to appreciate with an oscilloscope, as it takes a second or two to reduce the noise since the voltage enters its input. At least it is what I have been able to appreciate.

For this reason, I do not know to what extent, it could adapt to a noise that was not constant in frequency.

 

 

 

The central weld that can be seen, is where the burned component was. Sometimes resistors as a fuse are used, but I'm not sure that this was the case.

 

 

 

 

 

I have also used them to filter out negative voltages, such as - + 18V

 

 

 

 

 

A greeting.

I've done a little more research tonight.


i was curious as to whether I am paying a sonic penalty by using a standard hard drive on my Startech extender vs. a flash drive for storage.

 

The answer is no. Now realize that I have an Uptone JS-2 powering the hard drive which certainly could be making the drive less of an issue vs. a flash drive.

 

And each of the Extenders is powered by Sbooster power supplies as well.

 

Finally, I tried Audioquest Jitterbugs on the port of the PC in which the Extender is plugged in as well as for the hard drive and microSD flash drive USB adapter.

 

Granted they hadn't been used in a while, but I was surprised that they brightened the sound. Maybe they do need break-in before I can make a more informed decision.

 

In any event, for whatever it's worth, that's what I discovered tonight.

Interesting photos - thanks for sharing.  Were you able to measure the exact noise reduction with the Dc iPur?

Hi Joel - And I had the exact opposite experience both for the USB in the REX vs HDD and the JB's - just goes to show you YMMV!

 

Cheers

 

PS Toobad the JS-2 can't power the REX - that would be interesting.  I believe 12VDC is the max for one of it's outputs - the REX uses 24VDC.

That cable to power my SSD drive by external LPS did not work.  The data part does not fit in the MB SATA slot - must be for an ext SSD drive only.

 

So I just ordered this one:

It's a SATA to USB power only cable - so I can use the regular SATA data cable from the MB slot.

For powering my ssd's I'm simply cutting the edges of an unused usb cable and a sata power cable and putting together the reds and the blacks..
