by the way
why are we obsessed with firewire to i2s ?
the bottleneck of the usb 2.0 is obviously not the cable but the chip and the driver.(if I understood right)
once usb 3.0 is released we will probaly have a usb 3.0 i2s bus soon.mentioned this for DD and he was not unwilling to make a new adapted usb pcb for the usb 3.0  std once it was released.
the beauty of the usb std is the "autorecognition" feature once you hook up a new device.has firewire this as well?
OR?

I'm reading with interest, if not real understanding, through this thread.  But, I thought I'd chime in on the usb.  Perhaps usb standards will change and whatnot... but, the thing that threw me off usb (usb out of computer into my Stello-usb dac) is that everything I tried seem to make a difference under usb.  On the usb outs from the computer, (both laptop and the "super" computer I built heh) I could always find one that sounded better.  Having any other usb device on with the dac-usb made a difference.  Shutting off all but the one usb port feeding the stello made a difference.  Every cheap usb cable I tried sounded differently (I still hold onto my favorite one in case there's a reason to go from the FW I use now back to USB ... it is a no name silver braid type that is much better than all the other decent cables I tried) ... and don't even try cables with ferrite beads, all three I tried sounded worse than my silver braid.  I even tried optical usb with a battery supply; it did not sound very good compared to my cheap silver braid 2m one...
point is
so much variation with usb makes me feel it is fragile  ... firewire has seemed more robust.

no tips needed; very straightforward
if you stack Buffalo on top of Ivy to have access to the Ivy dip-switches it´s smart to connect inputs from B.,outputs and  psu connections on Ivy BEFORE you mount the Buffalo on top.otherwise you´ll have difficulties.
also take into account signal cable lenght between the cards so you can "flip" them apart(as if they´re hinged in one end), even though they are connected with wires,for possible future access needs.
ref .support it´s no problem firing up Ivy w/o anything connected to outputs as "load"(e.g.for testing purposes)
I went for scheme 1 in Ivy manual but R 17-20 are replaced by jumpers(0 ohm resistors) and you´re supplied with C 13-16:THE MANUAL IS NOT UPDATED ON THIS.
also with usb in all dipswitches are in "-" position
DD´s usb card worked just fine.
good luck

the funny thing about this dac is that I noticed details in the hights,that I never knew existed! Happy
this despite that the hd650 is only driven by a vintage Pioneer integrated from the early eighties
extreme resolution all over the spectrum
will test on trios tom.

Me !!! Do you have a ticked for the whole family ?
We were there last May (and in a couple of other states), and we're still talking about it every day.

Anyway, this is a nice base ...
I will build the DAC next Saturday, and I will be using that powerful PSU ... (but I have the IVY as well).
So, may you be able to find an internet connection any 8 hours after Saturday ... I will post the results here of course.
But I'm not sure yet how it can be better than what I have right now hahaha.

Have as much fun as we had and say hello to many nice people !

Hi Peter,

You ventilated your thoughts about completing the Buffalo last Saturday
I am just curious about the progress with your Buffalo and Ivy. Looking forward to your esteemed thoughts referring to the two items, maybe with its standard powersupply. Hope you share with us what your planning to mail to Leifchristensen about your findings?
Thanks for the beautifull player btw!

Hi Ed,

Things worked out differently from what I planned.

1.
It appeared that it is not just a matter of attaching the Buffalo to the "powerplant" Happy because the output of the Buffalo is + and - volt while the powerplant was setup for balanced DACs with + only, hence + and - connected (I hope you can follow what I mean, but this is about 2 DACs per channel, not in parallel, but balanced).
Of course I can change this, but it means work which implies work again when it needs to be reversed (and remember, this is only testing around a bit). So ...

2.
So I deciced to build the IVY and all, which was completed Sunday morning.

3.
From then on I'm struggeling with the Buffalo DAC ...
RCA out gave hum all over (and I mean MUCH hum and a little bit of music), and I decided to setup a balanced means of output. Officially my amps are not balanced, but since I planned to make 'm like so, it was a good reason to do it now.

4.
This means of "balanced", gives some (but too much) hum by itself, thus also to the NOS1 DAC.

One very well could say that right now I am in a big knot of ground loops and 10ths of meters of shunting wires are all over, and the one setup doesn't suit the other change (and creating one acceptable setup really takes hours).

And additional problem I have, is that I play without preamp, but when such a hum is exposed as the Buffalo does so far, this is not allowed (breaking windows). So, the pre-amp has to come in again, and that by itself destroys the ground loop setup.
So I'm in circles ... wackowacko

But as soon I have some result, I will post it !
Peter

PS:
Don´t you lack a common star ground in your drawing? to chassis even?

Hahaha, I gave a smart answer there. Now I better ask you Leif !

Hi Ed,

Things worked out differently from what I planned.


Morning, Peter,

I will keep my attention on your progressings.
I must say, I am really satisfied with my own DAC (so far!). I have built, about two years ago, the Doede Douma Dac DDDac version two. The same one  Leifcristensen has. Mine is USB and battery-powered.
The reason I am looking around is, I can only play-back 44/16 files.
Since I am a llifetime-liverecording enthausiast and and do my recordings (orchestral and choir) ,for the last eight years or so on hard-disk 96/32, I need a really good way of playing back those files as well without the need rebuilding them to 44/16, as you will understand.
The things I am using now for that matter are the prodigy HD2 soundcard(intern), or the M-audio USB(extern).
I am looking for a better solution!
But......since it's all DIY and hobbying, for the sake of good musical audio reproduction, low cost investments are always a preference!

Enjoy your music,

Ed

Colony Hotel Miami Beach calling Cool
I use the original psu´s that deliver +/- 15 to the Ivy and the 6,0 and 6,6 to the dac.
I did not get fifnished with grounding scheme but it was dead quiet but had sonic dropouts due to gnd loops.
Acc to TP guys I will connect all gnd between the psu outs (the minus on the dac supply and the gnd on the Ivy supply)together and the DD usb pcb that only gets 11vdc will also be connected to the other psu´s by the gnd terminal.NO gnd between dac and usb card I2S out.
this way all should be well
if problems I´ll check this page L8R 2 day
best
Leif

Ok, up and running here. Can't think of why it didn't work before, other than the rather unofficial way I stacked it (see the locomotive below).
Before I disassembled that several times at trying, so it wasn't about a loose connection I think. Now both halves are loose and everything looks right at first glance.

Must test it for its merits later; today there's visitors. And Chritsmas music only of course. Happy
