Strangely, with some 320k MP3 music tracks playing from my iPod via RCA or phono interface, the music sounds really good. I presume this may be due to the fact that the DSPs in the processor kick in when an analogue music source is selected. Do you have any idea about this ?
So far my 7030 has been working as expected. With home theater I tend to "set it & forget it" although tweaking my stereo gear is an ongoing process.
When you play music via analog inputs you have a choice of modes to process it. As I remember:
BYPASS = stereo, no bass management, DSP is bypassed, only lt front & rt front speakers playing full range.
STEREO = stereo + sub, lt & rt front speakers are bass managed via DSP so subwoofer is active, no surround processing utilized.
5CH STEREO, 7CH STEREO, Dolby PLII Music, DTS Neo, etc. = DSP utilized for bass management and
processing stereo into surround so you'll have 5+1 or 7+1 speakers playing depending on the mode selected.
One thing I've noticed with A/V processor music processing modes is that most 5CH & 7CH STEREO modes increase audible bass. At low levels it can sound good although it can get bloated at higher volumes - but - the modes are good for spreading music around a room. Modes like Dolby PLII-M & DTS Neo generate surround channels and attempt to simulate imaging but don't generally bump the bass like 5CH or 7CH modes do.
What happens is that sometimes a DSP mode can make a compressed track sound "better" depending on personal preference. If a track is compressed and "thin" sounding it may sound better with 5 or 7CH STEREO applied but another track that's bass heavy to begin with may sound bloated. Sometimes a track just has lousy stereo imaging so applying a mode like PLII or Neo can help.
At one point I had a 5.1 surround setup in my bedroom and due to the bed not being centered in the room I always listened to music via Dolby PLII-M because it allowed me to finagle the imaging at the listening position and utilize the sub. As much as I listen to "purist" stereo music in other rooms my bedroom really needed DSP to sound decent.
How music "sounds" is very personal so if you like the effect of whatever DSP mode you're using has on your iPod tracks stick with it. Just like a rug can really tie a room together (Big Lebowski
) sometimes a bit of DSP can work wonders.
