thanks Bob and Korben

really interesting to see how you guys are getting on

i'm planing to use Jriver or Fubar in windows7.

i also run Slacko which i find sounds pretty good if a little clunky interface wise. i really must try to get a handle on this Linux thang and mpdvoyager especially.

Korben

you may remember that i'm planing on trying with a 9023 based DAC along with a few other options. So your initial impressions give me a good deal of hope.

really good to hear from you both

I have win in virtualbox already so worst comes to worst just bring it to the headfi meet and I'll bring my imac and we'll get it sorted

Or it can obviously be arranged sooner too.

Ok, I have it working well now. I had an old version of audirvana that wouldn't output DSD, I upgraded it and it is working great. I get voltage on the DSD pins.

Since the firmware upgrade, the crackles in the sound have stopped. I am still using the 'best' firmware with my Buffalo II, I haven't tried the default firmware yet.

Hi shoom

Glad to see you here.
I hope it too, I'll go BAL with Subbu's DAC V3 in I2S mode
Maybe a "HomeMade switchbox" to select from I2S and SPDIF sources too

Hi Korben

''Glad to see you here''

thanks

Sounds like an interesting project you are starting and it will be interesting to have your thoughts on that once you have it up and running.


For my part I gave up on SPDIF a while ago (well pretty much when I heard what USB I2S could do ) but that’s a personal choice which may not suite others. I'll be using mine with a Teleporter which gives some isolation from PC - DAC grounds and makes swapping between different DAC USB/I2S combinations a breeze. Again not everones idea of a party but works well for me in my set up to my ears.


One thing I have been wondering.


Has anyone tried stripping the 3V3 LDO and using an external PSU to power the Amanero?

It’s sure one of the things that I’d want to try (but only after running the board for a while to make sure that all is well). If the jump in SQ I achieved with errr another USB/I2S board is anything to go by it may be worth trying.


OR


May make no difference what so ever.


But


I’m curious.

greetings,

If anybody tried the iso7640 isolator circuit, are pin 2 and 15 grounded to their appropriate grounds? The schematic does not seem to connect these pins but the datasheet indicates them as ground pins. It would then be easier to solder the .1 cap as these need to be less than 2 mm from the vcc pin.

Hope someone can help.

thanks

yes they are, they give you multiple options for routing as well as providing more effective grounding for the device. if you havent bought it already, I would suggest you get either NVE IL715, or SiliconLabs Si8440 both are pin compatible and have lower skew and propagation delay

Hi,
How would you compare the NVE with the TI ISO7240 or AD Adum3440?

@qusp: thanks
