The way the ESS Sabre chip handles SPDIF results in impressive sound quality. Leon beat me to the integration guide but it does contain a wealth of info with BOM at the back of it.
I'd look at a BIII SE with IVY III or Legato I/V stage. I've tried both and prefer the Legato. The Legato has a headphone out but I can't recall what they can drive. Power wise I tried both and prefer the warm running Placid HD/Placid HD Bipolar shunting over the linear supplies. You need good ventilation for the Placids or use a suitable thickness enclosure that would work as heat sinks for the power chips.
At the TP site, you can check out the manuals for the I/V stages for further config info.

Hi guys,
Could someone help me with the data regarding Vcore (1.2V) current consumption figures for 44.1 till 192khz sample rates?
Thanks,
Mihai

Everything as long as they are dynamic cans. The LME49600 buffer is capable of delivering 250mA.
Do you have to use a output stage? Isn't it possible to bypass this and wire directly to xlr jacks. I use a dbx driverack after my current DAC a Roland m1000, I use the dbx to tune the powered monitors and the sub for the room.
No - you don't have to use an output stage. There are some definite drawbacks to not using one, but it still sounds great.
If you don't use one, you will likely want to AC couple the outputs. Output capacitors of 2.2-10uf are commonly used.
You can always add an output stage later.
I don't recall the exact numbers off the top of my head, but if you plan for a max of 75-100ma or so you should be just fine. You can adjust as necessary.
Thank you Russ,
Are there specific Output capacitors you could recommend (brand,make model)?
It is possible to work without an I/V stage, but it'll cost you some performance. If you're looking for the best performance, add an I/V stage like fi. the IVY3.
You are welcome.
I have actually had really good success using the Dayton Audio film caps.
(I have no affiliation other than being a happy customer)
Dayton Audio PMPC-10 10uF 250V Precision Audio Capacitor 027-244
I have also used Auracap and others. Really any good quality film cap will work well.
[FONT=Calibri, Verdana, Helvetica, Arial]Hello Russ,
Thank you again for your last post -
[/FONT][FONT=Calibri, Verdana, Helvetica, Arial][FONT=Calibri, Verdana, Helvetica, Arial]So is it fair to assume [/FONT]if I order the following:
1 - Buffalo-IIISE 2-Chan DAC Mod+Trident RegSet
1 - Placid HD Power Supply Kit
1 - 9V+9V (15VA) Power Transformer
1 - 4-Pack of Gold Hirose U.FL Connectors
I can be up and running?
I know I will still have to buy.

If your amp already has a DC blocking cap, then you don't need another. I have my Buffalo DAC directly connected to Hypex UCD180 modules. I do have an RC low pass filter though.
If you want Digital volume control, then you also need "volumite"

From some earlier posts in this thread it appears that at least some people are successfully using the Amanero USB interface with the Buffalo III-SE. Unfortunately, I'm not having any luck. Here's how I wired it:
Amanero ---------> BIIISE
DATA ---------------> D2
BCLK ---------------> DCK
FSCLK ---------------> D1
GROUND ------------> GROUND (x2)
The wires between the Amanero and the BIIISE are about 1.5 inches long. I'm using an Arduino controller (HiFiDuino) to handle switching between SPDIF and I2S, Foobar2000 as my player (set up to output to the Amanero using WASAPI), with a 6 foot USB cable connecting the Amanero and my computer. I'm getting total silence. Any ideas on what I'm doing wrong?

The Hifiduino s/w only controls the chip registers for spdif/I2S switching. The BIII has external devices to switch between SPDIF and I2S that the hifiduino s/w doesn't know anything about. This could be your problem.
@chryses:
My experience with the B III, the Amanero and the Hifiduino s/w says that it works without any problems, i.e. you just wire it like you did and set the hifiduino for I2S operation. That's it. It has worked just fine that way in my case.
Now, the B III SE by default expects a s/pdif signal in the s/pdif input. In order to use the I2S/DSD input you have to select it by connecting a switch to IP_S and closing it. Have you done that?

1. Check if you are indeed sending data, and if the volume is ok.
2. Check your usage of IP_S: this switches the input of the BIIISE. It should be connected to a digital port on your Arduino board, and you should control it in the software (i.e. alter the code).
