The KillerDAC Audio forum

I can't wait for these developments to happen.

But I am wondering if USB is redundant?

It's very frustrating, especially the Pro side of things having gone through 1394 (firewire), thunderbolt, USB etc
We all should be using Ethernet. I could never work out why dig audio over Ethernet took so long, it has huge BW and is reliable.

There are a few Ethernet options out there, it depends how you want to set the system up. The best are pretty expensive.

It's ok if you dont mind sitting a laptop computer in your audio system.   

But that isn't ideal, from my perspective.  And driving a keyboard and mouse, to queue music, detracts from my personal enjoyment of the music.

The Pi device I am using, doesn't require USB.

Roon backend queues the music, sends the data over the network to the Pi,,, the Pi receives/buffers/reclocks and sends it directly out the i2s outputs.

I am not suggesting it is technically superior.   But I am suggesting that having to handle a laptop computer in the audio system isn't required.

The Pi looks good but the only thing I'm not sure about is if it has galvanic isolation. This makes things more complicated
as you have to send clocks -> back over isolators to wher I2S is generated. JLsounds does all of this.

Just implement what you have properly and you will be done.
 
There are quite a few possible options with 1541 up to full
stereo, 2 chips in simultaneous mode. 

I have just finished upgrading another PDX. 1704 DAC chips running directly off USB bridge, sans
digital filter. Will be testing next day or so. I'll post some pics later. It's a very clean build, max
distance between USB bridge and DAC chips = about 20mm. Both ground planes joined.

Next DAC will be running DSD256 / 512 native directly from USB bridge.
 
We are spoiled these days with options but knowing what to do / how to configure
the whole deal is the real challenge.

Noooooooooooo. But next on the agenda is one like yours.

Cool.

Can you drive it from your phone?

One for the less hard core and less capable, like me

The guy that sells them on the bay has been doing so for years now, and as an easy fix I went with one, the result was nice with the music flowing and sounding more natural.
I guess just like the regular NOS mod does, though as I have never done it I wouldn't know if or how much difference there is or might be.

Anyway, after adding this in place of the SAA7220P/B chip there was no muting so that track noise at the start of CD play and when starting a new track via the skip function, so added the work around I read of on the lampizator site, and now playing as it should. Soldering that wire to the 7310 was challenging for myself at least.
