I'm getting very excited to build an Opus, and waiting for all the parts to be in stock at twisted pear. It looks like the Opus and LCDPS are both in stock, but the only part missing is the USB/SPDIF to I2S modules.

Does anyone know of any other SPDIF or USB to I2S modules that I could use with the Opus?

Thanks for the responses, I think I'll wait for the TP module to ship since the DDDAC unit is so expensive (thanks for the find though!). It was beautiful seeing the update on the TP site this morning, brightened my day

It seems they were out of stock for a long time (the buffalo looks to be a bit popular) and I had no idea when I would ever get my hand on one.

Now the case design begins

BTW Timjo: Are you planning to build with a balanced, ballsie, or IVY output?

I'm interested to hear how it compares to your Duet. I almost got a Duet but I had too many ideas floating around my head for the casework and had to DIY something.

Well, I had intended to use the Ballise, since I am a SE headphone user, but with Russ' latest tease about the IVY (http://www.head-fi.org/forums/f6/twi...ml#post4412693), I may wait for the IVY manual to be released before ordering a line stage section.

Ultimately, I still want to build a tube based line stage using a modified Aikido amplifier, along the lines of what regal has been talking about. http://www.head-fi.org/forums/f6/all...os-dac-337755/

Thanks Brian, I noticed the message on the site yesterday morning and ordered right away!

The tube line stage is an intriguing concept. It could be interesting to pop in something like the Darwin source selector to choose your output stage (SS or tube). If you go that route I'll be interested to hear it at the next local meet

I was pretty much sold by that message about the IVY, mostly due to the attenuation of 2nd order harmonics (I think I recall the presence of even order harmonics being attributed to harsh "digital" sound). I'm also waiting for the manual, but I think that will be the route I'm taking.

It's the other way around. Odd order harmonics are supposed to be the "bad" ones.
