your profile says 09v6a.....are you still there or?
does your rec q. set refer to 09w6 or 7?

pity
but you´ll come up with something
in the meantime:
the buffalo sounds excellent despite os.
BUT the sound varied very much with gnd scheme and after I replaced the onboard LM317 regulators on the double psu for the buffalo with LT1085 the sound took a turn towards sweeter and more nos like
will do same on ivy where 317 is replaced by lt 1085 and 337 by lt1033.
that´s it for now

have it on a number of pc´s (3 :1 stationary and 2 laptops,one for remote control of musicserver and another for bring along demos)
just check procedure with P and you´re set to play

hmmmm
have you actually LISTENED to it?
or like Gary Dews of Borderpatrol said:
if it sounds good , it probably is

ok looks fine but I would not use screw terminals for signal connections
just my 2 cents

and now I´m off to radio shack key west with my boys and wifie,since it´s raining anyway

Colony Hotel Miami Beach calling
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

#¤#"/&&%&%/  it sounds way too lightweight! no impact!??
hey but wait ,my wifie has stumbled in the powercables to the right basstower
he-he .....now we´re talking business! the bass resolution and impact is tremendous!and everything is ahh,soooooo relaxed, despite the extreme resolution.3D is out of this world!in full width
whow this is hot
anyone want a ticket and packet holiday with complete family to Florida?
I don´t think I have the time
This is f#¤%)/¤ close to a clean world top analogue rig w/o the sparkling fire clicks!
and this is with a relatively lightweight, if well implemented psu
the whole shabong is only thrown into an old hammond steel chassis
who cares,it sings anyway
all 4 now! the packing was done in 5 minutes and I´m into my Cancannon Petit Sirah redwine glass.
holy sh*t,I´ve never heard those miniscule details be4.
Peter get on 2 it right away! it wipes the floor with the 5 tower dddac and the 4xad1865 AD labs from Romania
merry x-mas and a happy new year to all

good luck
the funny thing about this dac is that I noticed details in the hights,that I never knew existed!
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.

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

IT PLAYS!
excellent heights on my sennheiser hd650 in the basement workshop
have made an extremely loooong playlist in xx to burn it in
will test on big system on thursday
now: REDWINE and wife!

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?

hello P
I know how to connect but I´m not sure I´ll make it in time.
Don´t you lack a common star ground in your drawing? to chassis even?
only difference in my place is that I will use Doede Douma´s USB pcb to start with and it needs a separate psu that´s almost completed.
Status:buff and ivy are connected together
psu´s  to BUFF and Ivy are not
x-formers to psu are connected and delivering
usb to Buff is not
ivy to output is not.
need a couple of hours more to complete.
PUHHH

Hello
I´m struggling with time since I´m leaving 4 x-mas holiday on friday morning.
I´m finished soldering the Buffalo + IVY + the 2 psu´s.What´s missing is making the regulator for the DD USB pcb and hooking up the wires between pcb´s and the output rca connectors.All is put in a previously used Hammond chassis just 4 testing purposes.
Maybe I´ll test thursday evening.Tomorrow I´m attending a heart starter medical training course since I´m a volunteer in a Norwegian naval rescue-organisation.They´re pushing ahead to make me head of one of the watch-crews.
Time is indeed a scarce commodity!
