A novel way to massively improve the SQ of computer audio streaming

[henke]

I just recieved 5 of theese LT3045 boards with 4 parallel LT3045 that I bought from an ebay seller:

 

 To early to say, but I think I like them. Thinking about changing the big cap which is an Jamicon @ 1000uF 30V.

Does anyone have any recommedation for cap change? They will be used in the USB chain mostly (two ISO regen and one Matrix element H pcie USB card) so current draw maybe will be at most 100mA per regulator board. Was thinking about Panasonic OS-CON 1000uF 16V but not sure.

Got me wondering if the supposed LT3045 on my board are legit. It says:

"LGYP

N912

827"

On them not "LT3045" as my MPaudio board. 

 

Have anyone seen theese type LT3045 package that I have?

Im wondering if one stick of RAM will sound better than 2 sticks in dual channel? I have 2× 4GB at the moment but I dont need the performance of dual channel I think and only 2.5GB is used. Has anyone any experience of 1 vs 2 sticks?

Try it, listen and switch a couple of times between one and two sticks.

But don’t forget to power down the steamer, disconnect power cord and discharge yourself on something that goes to earth.

 

Yes maybe I will do that thought I ask so I know if it's worth trying out. Kind of hard to A/B:ing the change also

Over here, I am back to bridged USB NICs hanging off two direct to CPU USB 3 ports. Zero PCH traffic. Bliss!

Sounds good. Thinking of trying bridged USB NIC, any specific models to look for?  Hard to find any "professional"

With Linux it seems the Realtek chipset NICs are best. My two cost $20 each.

Actually having plans on running it bridged to an eRED-DOCK from an USBridge sig on Linux based OS, all built in a chassis with an lps inside. Do you happen to have a link or name for the USB NIC/s your using, thanks.

 

This seems quite good with 4kV optical isolation

It has Realtek RTL8153B chipset

Although a bit worried the isolation might add more noise than one without

One example is a TP Link UE300. $10 on Amazon. Likewise this one is also a Realtek RTL8153 device and works well with both Linux and Windows.

Thanks will look in to it. Quite an contrast to the crazy audiophile prices. 😁

Hi Dave , 

My usb chain was quite extreme 

supermicro mobo with clocks clocked by sclkex clock board 

sotm pcie usb card clocked  by sclkex board

Sotm tx usb ultra clocked  by sclkex board

dx usb hd clocked  by sclkex board

and all the associated psu .

without the psu the hardware alone was other  3 000  $

Now I have e-red dock 440$ , etherregen 650 $ and jcat netcard 440$ 

Total cost is 1500$ only 50% of previous set up and sound quality is much much better and it is simpler to use !

FortunatelyI was able to sell my previous dual pc set up and also several unused psu.

 

In this case simpler is clearly better .

 

Hello Jean Michel,

I wonder how your ered-dock etherregen and jcat netcard(server) are connected to each other and to the LAN? How do you stream to the ered-dock? Where are the music files stored?
