Apple Airport Express Very Cool Product

Hey..I already posted this below, but not sure if folks will read some of the older threads...so here goes again, my appologies if this is bad forum behavior:

Hey all,

Newbie here..so bear with me.

I'm currently sending musci from my older G3 PowerBook laptop to the Airport Express unit, and than out of the AX unit via mini-optical to toslink into my HT receiver (Onkyo 502).

This sounds pretty good at this point in time, but I'm interested in how I could improve the sounds.

After looking at products like the Waveterminal, it seems that I have to power that unit via USB. Since the whole point of this (for me) is to be wireless, that's not an option as I don't want to run a USB cable from my laptop to the Waveterminal device.

Can any of you guys recommend an entry level solution that would be able to take the toslink optical output from the AX and convert to digital coaxial, and also hopefully allow me to improve the final sounds quality coming out of my Onkyo 502?

As a further fyi - for speakers (not that it really matters) I'm using a 5.1 system with Polk 35/25RTi for the front and back, a Mission center and a HSU sub.
Thanks for any help!

Chris

Here are the guts of the AirPort Express. I have started modding it:

Here's the same response -- look at the following thread. I think it addresses this issue thoroughly.

Thanks,

My net take-away from that thread than is pretty much:

" It means if you have a good toslink receiver that this is a good system to use, without modification."

Sounds like another component converting the toslink to coaxial won't add much.

Thanks,

Chris

Actually, converting the toslink to coax eliminates a few components at both ends, reducing the jitter....
