Perhaps I sound like the audio snob that I am. If you have separates (preamp, tuner power amp) or a high end receiver, the difference between lossy and lossless is obvious. It is most striking when cranked. :banana:
Still, there are a lot of DTS-discs out there which sound a lot better than a lot of the SACD/DVD-Audio/Bluray-discs out there. Meaning you can not take for granted that a lossless disc is better than a lossy one. Of course if all other parameters are exactly the same, the lossless wins.
