I'm with William... so we're 2 in a thousand
I've tested over years many *MUSIC* DVD's and BD's... and with a "medium-high" class equipement (Oppo/NuForce + Rotel + Dynaudio) the sound quality differences between lossy formats (AC3 and DTS) and "hi def" sources are (to me *and* my wife...) quite noticeable.
I've even tried some DVD and DVD-Audio in similar class auto amplifiers (Bang & Olufsen on Audi and Mark Levinson on Lexus) and there's a strong difference between AC3 640 and DTS 1.5, and both of them inferior to stereo 192KHz (DVD Audio).
In my humble opinion if you're going to listen at MUSIC (not movies), DTS is my minimum acceptable option: in some cases I've heard it playing really well.
Obviously the new lossless format are better, if available.
With classical or jazz music you can easily feel the differences, while with movies... you need some good (and big) speakers to hear a difference between DTS and DTS MA. Always in my humble opinion.
