Does the assembled dac for $75 usd come ready to use? Power supply, case, etc? I can't seem to find much info on the website. What is the capability for USB connection? I have many sacd rips I have made that are 24/96 24/192 etc.

The Opus is basically just the DAC by itself and it has balanced output. If you want to get SE output you will need to either get the following:

Ballsie Lite Converter

Or Line stage with built in Ballsie

IVY

Even if you're going to go fully balanced, I would suggest you get the IVY board, it is much better for sound output.

You will need a power supply for the DAC. Depending on your budget, you can go these way. Upper is least expensive solution and lower is most expensive but better as well

1- Use LCDPS power supply to power analog and digital sections of the DAC independently or use one side of the LCDPS to power both analog/digital section of the DAC and the other side of the LCDPS to power the SPDIF tranceiver/MUX/USB

2- Use a Placid HD power supply to power both the analog/digital section of the DAC or use two of them to power them individually. Use LCDPS to power the SPDIF tranceiver/MUX/USB and use a Placid HD Bipolar Shunt power supply to power the IVY stage

3- Use any combination you like but the Placid HD Shunt power supplies are the best to power the DAC and IVY Stage. The tranceiver/mux/usb can all be powered by LCDPS.

If I was going to build this, I would use the following:
Opus DAC
Placid HD Shunt to power both Analog/Digital section of the DAC
IVY III Linestage
Placid HD Bipolar Shunt Power Supply for IVY III
Your choice of tranceiver/mux/USB
SPDIF tranceiver with I2S output
or
4:1 Mux receiver with I2S output (new version coming out soon...
or
USB receiver with I2S output (new version coming out soon...)

And of course transformers
Power transformers
You can use the 15V for DAC and IVY and Transceiver/MUX/USB. The 9V should also work well with the DAC and Tranceiver but not the IVY

Enjoy!

Ok, thanks for the quick reply. Does anyone sell fully built units? Looks a little out of my price range, but maybe someday soon.

Is this 200$ assembled with a case and everything? Or you can solder/assemble by yourself?

If it is fully assembled and with a case, you won't find anything here close to do this.

I would strongly suggest you save another 200$ and invest in the opus. It is a great DAC, you won't regret it at all.

Thanks
