I've got three more lt3045s to use in series with the 3 already in use.  I hope to get the soldering done tomorrow. These little things really have a spectacular impact on SQ.  Glad to hear you were successful.

Spent the morning soldering, and early afternoon listening.  Thumbs up on the serial lt3045 solution.  More blackness, image stability and timber are the results here.

I think I have touched many magic buttons in my setup the latest few day. My sound have never ever been this great as it is right now! The image depth is crazy good as if the the depth have gone into the next level. Details that use to be crystal clear is now astonishing! Bass notes that use to be deep and nuanced is now filled with fibers with loads of textures. Mid-range have improved quite a lot and I almost feel releived listening to well known music.

 

The improved grounding have really revealed my latest changes a lot. The LT3045's, the new ATL starquad and star-earthed PSD, the ATL 8 conductor USB cable with JSSG, new ATL DC starquad cable with JSSG and additional ATL starquad AC mains cables have all contributed to this amazing transformation, that feels like going from 3D to a full blown 4D. I am so so happy and are smiling from ear to ear right now! ?

 

It looks like the DC sockets will come tomorrow, so I can add the LM317 to the mix during the weekend. I will also see if I can figure out how to ground the DC- output of my Brooklyn DACs internal SMPS to the star-earth receptacle on my PSD.

 

I am really looking forward to see how that turns out. I feel blessed right now when all the work is so greatly rewarded! ?

Where did you find then tapatrick the HW cap?  All I found was UHW.  

 

 

Ah yes they are one and the same. I had the same puzzle and contacted Nichicon to ask.

Happy days! Likewise here, I can’t wait to get home in the evening, clear the decks and have an amazing listening session. Just like when I was younger and  vinyl was king and everyone sat around with closed eyes really listening AND enjoying the sounds ....?

Really great to hear Patrick! ? This is what it is all about. Finding happiness in the music. Thanks for your great tips. I am really looking forward to receive the BluWave now. 

 

Luckily I've got a turntable. You're welcome to my place and flip vinyl records any day! ?

How would you define the effect of low noise on the power input with these regs or are you saying this is not the reason for what is happening?

 

While lower noise into Regs like these is always beneficial, what is more beneficial is a VERY low output impedance combined with low noise over a wider bandwidth than most generic voltage regulators are capable of.

I would expect that a 1A LT3045 with it's parallel LT3045s, could sound a little better than a single 500mA LT3045 when supplied via a Pre Regulator or fairly low noise power source when powering a device that needed <500mA .

So far, I have only seen brief specifications for the LT3045 , but it could be worthwhile trying them with a larger value electro connected across their output if their specs permit this. The LT 3045 would be designed more for powering low current devices needing a very low noise PSU. They could be ideal for things like Phono Preamps and Preamps needing no more than a +15V supply.

Congrats @Cornan you made so many changes lately, it is hard to know where the main contribution is coming from

My switch takes 1A at 5V and is powered by LPS-1. If I want to try two of the LT3045 in series, what output should I order? The LPS-1 max voltage is 7.5V.

I followed most here with a 7v-6v to 5v.  Both will work.

Cool, Thanks.  I watched some videos and I think I can swap them out.  I too just finished soldering  up a 6v to 5v which is for my SU1, which is out for repair now.  My very first pcb soldering job and it all went well.  Whew!  ;))

 

I'm now waiting for more chips and Teradak to go further, and to be  able to actually hear these babies.  So stop saying how great it is lol

Guys

 Just remember that the 1A LT3045 PCB is designed for a maximum of 1A, and should not be run at this current , except for short term peaks. It may also need additional heat sinking of the LT3045s when run at fairly high constant currents, unless there is only a quite low voltage differential between Input and Output. e.g. 500mV.

However, when running at such a low Input-Output voltage differential, you may also need to take into account any momentary sags in  output voltage of the PSU supplying it under short term current "spikes"

Thanks so I need to get ine with an output of 6V and another with an output of 5V.

Do the green screw connectors which sit on pcb come with the board you or you have to buy them separately? What are they called and where do you buy them if need to buy separately; Amazon, Digikey? Thanks.

Larry: You are using 2 or 3 regulators?

2 in serial, for the Adnaco and usb card. One 6 volt for Regen with split to 5 volt for DAC vbus injection.

 

Moved ISO Regen to behind PC feeding lush cable to DAC. Just an incredibly rich dense image with high detail and depth.

Thanks Moussa! ?

There is no doubt that the corrected grounding paths was like cleaning the dirty reading glasses. Now ISO Regen sounds just great however I use it (GI on or off). Clearly a loop going into the IR. That loops seemed to make my system very sensitive and gave me double messages in terms of SQ. Grounding is really one of the fundamental things that needs to be right for a system to bloom. Lesson learned! ?

 

After cleaning the IR goggles there is no doubt that the LT3045's in series is an awesome upgrade and that my new USB cable is quite a bit better than Elijah Audio K-Lite in my setup.

 

The PSD have clearly improved things, but I'll need to swap it back to know in detail what those differences are. Deeper and tighter sound stage is however clearly a contribution. It also feels more relaxed. I am sure there is more to it, but I'll need to make that swap to know for sure.

I run 4 of  them with a 1000uf ELAN on output sid with very good result,

Yes, you order one 6v board and one 5v board and the LPS-1 set to 7v.
