What are the advantages of having a receiver decore an AC3/DTS source signal versus having PowerDVD/etc doing the same and then feeding the 6 channels output to an amplifier? The reason for my quesiton is the following:


I am using PowerDVD 4. The software is doing the acutual AC3/DTS decoding. I then feed the output of the SoundBlaster Audigy to the "Preamp IN" of an older amplifier (Pioneer VSX 9700S). I must say I am very impressed with the quality sound. How would the quality of the sound differ if I were to feed the SPDIF from the same card to an AC3/DTS receiver?


Thanks

One major disadvantage of decoding in a PC is the sound card. A PC's mainboard is a relatively noisy environment (from the RF point of view), and this _can_ effect sound. Decoding in an external box can help, as external decoders usually aren't such noisy environments.


Not to say that everybody will hear this difference, but it's one (of possibly many) potential problems.
