Building a DIY Music Server

Let me just say that after a night of playing the sound blew me away tis morning, CPU temp with high res streaming (24bit) is already below 50'C.

 

I am struggling with my i2S interlink though, does anyone know an RJ 45 connector for high end? (I have the telegartners but those do not work well enough for soldering on my own proprietary wires, or rather to keep everything in place)

Had to battle high volume noise this morning, troubleshooting the attanuator and DAC lead me to the I2S interlink, and it yet again failed...with almost no movement, I left the gear playing last night.

Just came back from the Berlin Audio Meet, where my prototype met these beauties

Nice horns. For some reason I can't picture them with digital source and imagine a nice vinyl-based source with them :).

How did your server sound there? 

I am excited for you yo try ULPS + Taiko ATX power supply...

hahaha, turns out I was listening to a Tedeska silver coil MC, thinking it was made by an enthusiast DIYer.... turns out it is among the best of best...now I am sure I want to do a head to head someday :-)

On the subject of grounding, do you connect the heatsink to the ground of the MB/PSU (EPS)?

Thanks Nenon!

 

I found that the heatsink itself seemed to 'quiver' and measuring I found a ground potential of like 5V, mind you, my MB and Heatsink sit on insulating wood, and most cases likely have a connection between heatsink and MB mounting points with ground connection.(just throught of that).

 

Sounds slightly more relaxed when grounded.

Fuses definitily make a difference, the best souding one is no fuse ;-)

My CLCLC PSU is waiting for the transformer and one MLytic, if only the transformer had already been delivered I'd swap in the Mundorf later. When we compared my prototype against a supposedly great Vinylplayer with a sophisticated arm and a new type of cartridge, through the same amp and speakers that latter sounded as if something was broken... so I can only hold my breath for the V3 PSU....3-4 weeks more waiting,

Hi All,

I have V3 up and running again with the Saligny rectifier. My system has never sounded so good. I have also inserted my very first audiophile fuse, the QSA Light Blue ($71, thanks for the tip @BCRich) and I am happy to report that this was an eye opening experience, in a good way. For those building out these designs, I would highly recommend going the extra mile and using a good fuse.

 

At this moment, its fair to say V3 has exceeded my expectations and is worth switching to, even with a single CPU rig. 

 

Cheers!

-Rob


What fuse value are you using for v3?

Large 5A slow blow.

 

250V I assume?
