I'd love to hear anymore feedback too.....would love to know what some of my favourite artists ( Michael Jackson, Toto, Billy Joel.....) sound like through the surround master ?
I say if there are any more questions about lossy/lossless they should be asked elsewhere.
So I'm glad and excited that you asked about the actual topic of the thread!!!!
I've been listening to some "standard" recordings (not matrixed or Dolby'ed, just regular stereo) in 4-channel mode yesterday and today and the results are very enjoyable. A lot depends on the mix -- stereo presentation, EQ, phasing, etc. The better the separation in the mix, the better the effect.
Essentially what happens is the mix has room to breathe. Little parts in the background that are buried far in the back of the mix become audible (for musicians, this would be a great way to learn parts by ear). It's pretty neat because you hear things in the recording that you never really noticed before. I listened to Steely Dan's
Aja and what I noticed was Fagen's little keyboard comps all over the place. On Wilco's
Yankee Hotel Foxtrot, there's lots of open space, and great separation between the fronts and the rears, really dramatic on the intro to "War on War." Right now I'm listening to Bruce Springsteen's
The Wild, The Innocent, and the E Street Shuffle and hearing how there are layers and layers of instruments (the guitars on "4th of July, Asbury Park" for example).
The Involve decoder manages to do the separation without essentially no "pumping" effect (sounds getting audibly softer or quieter as they're processed). This is the real magic of the unit. Other processors have pulled off some of the tricks, but when you hear the sounds getting processed, it ruins the illusion and it starts to sound like you're not listening to music.
I have a Sansui QRX-999, so I was already familiar with listening to stereo recordings through QS systems. The Involve decoder just sounds much better than the decoders on my QRX-999 ever did.
Obviously, this kind of device is not for everybody. Purists won't like hearing the mix get artificially messed with, and there are moments where hearing that much more audio information can actually get a little overwhelming.
But regardless, it is a very cool sounding thing. You definitely do NOT need to have QS (or SQ) recordings in order to enjoy the effect. The recordings you mentioned (Michael Jackson, Toto, Billy Joel) should sound pretty awesome through it because those were very well-mixed records.
Note again that I haven't tried the 2-channel TSS or the 5.1 modes yet, just the 4-channel.
