I am now using one 2gb memory module on the X10SBA. I am using crucial memory modules. 

I will look in the memory you recommend as lowest current draw. From my reading I got the info that Samsung memory modules were very energy efficient.

 

The ones from Micron should be a joke because the current draw seemed to be nothing to write home about. Samsung ain't too bad the and lowest numbers of M471B5674QH0 are kept under 500mA. SK Hynix should be fantastic and HMT425S6CFR6A would give us numbers that are belowe 400mA. I just kept looking but Crucial might not be willing to publish any numbers or something.

 

It ain't an exhaustive list by any means, just giving everyone a glance at what kinda DDR3L memory modules we could get on the market right now

 You keep saying this, but I think you should discuss this area with John  Swenson before making further pronouncements

as to how series LT3045 can achieve this. Why should this be any different than using say a LM317T Pre-Regulator before the LT3045 ?Remember to, that the 0 volts line is connected all the way through too, perhaps to either an SMPS PSU or a Linear PSU which MAY also have it's 0 volts earthed directly, or via transformer Primary to Secondary winding capacitance to mains earth..

A series LT3045 can't have a lower residual noise output than a single properly implemented single LT3045 either.(Ultralow RMS Noise: 0.8μVRMS (10Hz to 100kHz)

Parallel LT3045 can however have a lower noise output than a single LT3045.

As I previously explained , unless the LT3045 have additional larger value capacitors at their input, (perhaps from the Filter capacitors of the PSU supplying it) there will be  added upper HF detail. Using another one in series, unless you fit a parallel larger value electrolytic at it's input too will further likely increase apparent upper HF detail.

Perhaps your system needs a little added HF detail, or you prefer the "airier" sound and apparent increase in soundstage that this results in ?

Perhaps Mansr or John can chime in on this and correct me if necessary, or explain how this "leakage" is reduced ?

Alex

 

Actually, the first time I noticed the leakage was with USB Regen (TI TPS7A4700) acting as a  5v voltage regulator for my Aqvox switch-8, so it is NOT something specific for the LT3045. LT3045 just sound better in my setup than LM317 in comparence. I think it have something to do about low noise voltage regulators though and I would count LM317T to that bunch.  It was quite clear though that adding a LT3045 to the ISO Regen cured that "leakage" (of some kind), which most likely was on its way towards the network switch via the Y-split DC cable connecting the two (Aqvox & IR).  The fact that I had the IR with GI off probably was making things worse at the time, but before I added USB Regen as a voltage regulator the IR sounded much better with GI off. The latter probably means that the leakage went through the Aqvox switch (instead of through the DAC). Also rememer than this was before JSGT, but I still had my Aqvox switch GND screw grounded and used different ethernet ports for input/output (read magnetic boxes). No JSGT on my floating SMPS at that point though.

All my LT3045s are so far in series. Still have´nt tried any parallel ones, but it is coming pretty soon (two single ps board by Stammheim/DiyAudio and dual matched board for DIY project).

I have´nt had this great SQ that I have now, but to be honest there is ofcourse much more to that than just the LT3045s. The Bluwave Spdif post IR and the balanced & floating IT was other things that made the sound jump even more than the LT3045s, not to say all the other things like JSSG, starquad etc. I am a big fan of "ambient" /"3D"/"airy" sound but I do not miss out on HF detail as far as I can tell. On the contrary!

Big, big difference when components are placed on vibration managed platforms. Years ago when I placed my AR CD-7 and BAT VK-5i pre-amp on an Symposium Isis platform and replaced the existing footers with Symposium solids couplers and Rollerblocks, the change in sound was nothing short of a major system upgrade. Bigger soundstage, more solid presence, clarity of sound. A sceptical friend that helped me assemble the rack was gobsmacked by the change. 

 

Vibration management is so important that I was contemplating atomic microscope active platforms to reduce vibrations. 

I know a lot about vibration management and its effects on the electronics, domestic situations are mild trust me on that and cables vibrating...

You are right in fact on my actual dual PC set up with gigabyte Mobo and celeron processor i have adjusted cpu and ram speed to 800Mhz with good results .

 

Unfortunately on the board i am testing now the super micro X10SBA , there is no provision in the bios to adjust cpu and ram speed

How would you connect the SD card? SD to USB adapter?

I think that if you already have your OS on an external HDD/SSD powered by a separate PSU, then it doesn’t matter how low the power consumption of the SD card is.

I don't how you know vibrations in my setup has mild effects. Haha

 

or that I listen to music loudly.  ?

 

I think you don't have an understanding how vibrations affect systems or you wouldn't say this. It's the micro vibrations that make a huge difference. Doesn't require massive earth shaking vibrations for the effects to be heard.

 

I'll continue to trust my ears and 10 years of experiments with vibration management. The changes are as profound as SOtM products.

Maybe it depends on who we're learning from? Roy still picked Intel X25-E for installing Windows since that's supposedly having the lowest current draw if we're talking about 64GB SLC SSDs. For the storage of lossless music files, he went for 512GB SLC CF cards from Lexar because pretty much everything else with a similar capacity would consume much more power.

 

However, Innuos didn't seem to care that much about power consumption and they're going for those 1TB / 2TB / 4TB Samsung EVO drives

We configure the SSD controller extensively to limit the amount of noise the SSD can do on the system, helped by the fact the SSD uses its own linear power supply as well as vibration treatment.

 

Since their SSDs are directly connected to the Triple-Linear PSU that's designed by CHC, I also suspect that part of the problem could be mitigated by those (relatively expensive) Mundorf capacitors as they're filtering the noise all the time.

 

We still don't fully understand how ZENith SE Mk.II (without ANY fancy clock upgrades whatsoever) could perform so darn well when compared to Roy's custom server after he invested so much time and money to "perfect" that.

And then here's yet another option if we're going for SD to SATA instead

Apparently someone managed to install Windows 10 on Macbook with a SD card

Maybe it depends on who we're learning from? Roy still picked Intel X25-E for installing Windows since that's supposedly having the lowest current draw if we're talking about 64GB SLC SSDs. For the storage of lossless music files, he went for 512GB SLC CF cards from Lexar because pretty much everything else with a similar capacity would consume much more power.

 

However, Innuos didn't seem to care that much about power consumption and they're going for those 1TB / 2TB / 4TB Samsung EVO drives

 

Average : 0.1W **** (Typical) = 200mA

Active Read (Average): Max. 3.1W(4TB) = 620mA

Active Write (Average): Max. 3.6W(4TB) = 720mA

~0.3A (heavy read/write) = 300mA
~0.5A when booting = 500mA

Maybe they could get away with that because of doing this?

Since their SSDs are directly connected to the Triple-Linear PSU that's designed by CHC, I also suspect that part of the problem could be mitigated by those (relatively expensive) Mundorf capacitors as they're filtering the noise all the time.

 

We still don't fully understand how ZENith SE Mk.II (without ANY fancy clock upgrades whatsoever) could perform so darn well when compared to Roy's custom server after he invested so much time and money to "perfect" that.

Thanks for the great links as usual!

Ifi power upgraded to sps500 level.

before use need charge up with special charger.

Here's another goodie from Zenith se. The AC input has a 'medical grade' filter. We can't see which one as its covered up, but it's a good way to suppress emi/rfi from entering the power supply - there are plenty available.

It look's interesting as it is much cheaper than SPS 500  . Could you provide detail ?

Capacitor type( supercar ? , voltage...) , regulator board (it look's like LT 3045 ) .

 

Which special charger are you using to recharge capacitors ?

I would like to know if tX-USBexp board can be incorporate in tX-USBUltra case.

 

 

 

 

 

Not with the sCLK-EX in the case as well.  Not enough room.  The tx-USBexp is a fairly big card, as big as the sCLK.

on an Symposium Isis platform and replaced the existing footers with Symposium solids couplers and Rollerblocks, the change in sound was nothing short of a major system upgrade. Bigger soundstage, more solid presence, clarity of sound. A sceptical friend that helped me assemble the rack was gobsmacked by the change. 

 

+1, I have the same exact Symposium rack and Rollerblock/coupler combo. Not a small difference at all, rather huge, even casual observers like your skeptical friend can easily hear the change for the better with this kind of equipment support. Sorry for this brief off-topic veer.

5A constant adjustable dc converter,Powerstor aerogel 2.7v100F ucaps,lt3045(can parallel more)

ifi power 9v step down to 7v with reg.

before use,need charging full the caps(3caps serial can 8v max,best: 7v),same as lt3045 voltages.otherwise lt3045 can smoke.

I bought 2 uspcb ,changed my diy silver bridge(0 resistance,extra short).Sound get duller,lifeless,flatter.

Very strange!!! I cant use this uspcb.
