You need to be aware that Toslink has bit rate limitations but with DTS it should be fine. A trained ear can spot lossy straight away, the drums sound squashy and with DTS the vocals develope sibilance sometimes with signs of a lisp. When we did testing many years ago I could recognise the phase being wrong. 96-24 DTS is better but as with all lossy techniques it's the stuff that's thrown away that counts and somehow I find myself reaching for a book, instead of just listening.
Even with Redbook, I've been researching as to why I can still hear differences compared to hi-res and why some people categorically cannot hear it, yet my own frequency response on a good day (it is external factor dependent) being 14 KHz. At first I thought it was to do with Shannon and Nyquist getting it all wrong but then when I started to vaguely get to grips with Proffs Whittaker - father & son, And cardinals, the maths do work but never takes into account the audibility of a harmonic of two waves, one of which is out of band, the combination which you can still hear. As the frequencies get higher within a low audible range, the 3rd a 4th harmonic can hit the Nyquist anti alias filter and this may also be the audio nasty which some of us hear. This makes it musically program dependent. So some CD will sound worse. I also do now believe that some folks are more tonally and pitch sensitive whilst others are clearly not.
Moreover those that transfer music note that even at 192-32, an effect can be heard if you record close to 0dB yet recording at -6dB sounds audibly superior.
On this I hold no clue but it does appear to work. Anyway enough of my rabbiting.

I know it's sacrilegious to admit this, but I can't hear the difference between lossless and high bitrate lossy. I *think* I used to be able to in my younger days. Actually I'm sure a lot of people who insist they can hear a difference would fail an ABX blind test, as I'm sure I would have. Yes, I know that Lossless is better technically because you're not throwing away bits.--
As with Daniel, I don't have a multichannel output from my computer to my audio equipment (although I'm hoping to resolve that issue come Christmas) just a Single Toslink cable (8 metres long for £10 and it's bit-perfect!) from my PC to Meridian processor, so DTS is perfect for me.
Until recently multi-channel digital outputs from computers has been prohibitively expensive. For example the Lynx AES16 soundcard. However, MiniDSP now have brought out their "Multichannel USB to AES-EBU or SPDIF interface" https://www.minidsp.com/products/usb-audio-interface/u-dio8 it's become cheaper, but still around $300 or £300 which is a lot of money for me.
Anyway, good music played lossy is still good music!
