Yeah can't go wrong really Paul.Worth being aware that the Toslink O/P is on a combined analogue stereo/SPdif optical 3.5mm mini jack output. So if you don't already have a suitable lead/adapter, get/order one before the Delock converter arrives & save yerself t' ballache of having to go out & find one. :^
Quite often these are also bundled with cheap Toslink leads.
Here's a link to some. >> .http://www.amazon.co.uk/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=3.5mm%20digital%20toslink%20adaptor
I have actually used my Delock in the second system into my Audio-gd NFB 12.1 DAC/Pre/Can-amp & the SQ is v good & I've tested it at sampling rates of up to 24bit/96khz. It seems to sound even Stephens with the USB input on the NFB 12.1, fed from my Syno DS213 NAS. :stereo:
