I am a newbie. I have been playing around with this audio stuff for about a year. After a series of upgrades I am pretty happy with my setup, which is stated below. I have found components that sound good to me and were priced within my budget.
When playing 5.1 audio source, my system sounds great to me. So for home theater, or 5.1 channel music, I am very happy. But when playing CDs or MP3s the stereo source sounds good when played out of my loudspeakers only. When I select a Neo6 or PLIIx my 6.1 configuration produces a somewhat muddy sound that lacks crispness. It's most apparent with vocals. It sounds OK, but when I switch to my loudspeakers it sounds noticeably crisper.
This isn't a big problem. It is fine for me to just use 2 channels. But I do like the surround benefit of the setup. So I was wondering if you think this "muddiness" sound I am having is a common experience. Or is this something I may be able to improve with tuning? I have positioned my speakers in pretty standard way: My loudspeakers are about 9 feet apart, about 7 feet from the sweat spot. The surrounds are directly to the side at ear level, pointed to the sweat spot, around 6 feet away. The rear speaker (single) is 6 feet away behind, and up high. There is open space behind the sweat spot, which I understand to be a good thing. The room is smallish to mid sized. I have tuned the levels with a sound pressure meter using a calibration DVD.
So my question is - can I tune my way out of this? I haven't tried moving speakers around much yet. Do you think that might help?
