These speakers were installed by the numbers on a quad core Vista 64 system using an Intel D975XBX2 mainboard after uninstalling the existing audio drivers and disabling the on-board audio hardware in the system BIOS.
The system worked perfectly with the 1.00.000 software first time …but my keyboard went crazy, repeating the first key pressed forever. The latest Vista 64 drivers (vs 1.00.013) did not solve the problem so I moved the USB connection from a powered USB 2.0 D-Link hub to one of the two USB 2.0 ports on a PCI USB card and things are perfect.
I like a full body sonic massage from my music like most guys I know but I also like to hear each and every instrument as a distinct component of the music I listen to, which is largely classical. As a test of both volume and clarity I played Henryk Gorecki’s Symphony No. 3 and was very satisfied with both the volume and the clarity. The piece goes from almost inaudible passages to overpowering volume, from symphony without voice to the marvelous sounds of Dawn Upshaw’s soprano voice.
I also played Pink Floyd’s Dark Side of the Moon album and was very satisfied with the volume and clarity of the Z Cinema system from the beginning heartbeat to the ending background chatter. The clocks chimed each one distinct from each of the others.
Even the mp3 files I use for background music on my web site played with more nuances than I realized were present in the music.
I have not played any surround source files (games or movies), only stereo source files so I can’t comment on the ‘Surround’ effect but I do find that SRS gives the stereo music a more open, large room feel without sacrificing any clarity. I leave it turned on now.
The listening experience on the Z Cinema system in my computer room is on a par with the Z 5500 system in my studio, which is THX certified and is also optimized for clarity, not volume.
On a properly configured computer the Z Cinema system is a joy. The only thing I would like is a Bluetooth link between the controller and the speaker system, and ditto for the Z 5500 controller; line-of-sight infrared communication links are too easily blocked in a cluttered environment.
Some thoughts to consider…
The Z Cinema system is optimized for clarity of sound, like the Z-5500 Digital system I have in the studio, not for blowing out all the windows in the house …however much fun that might be. In my computer room (14’x9.5’) there is more than enough volume for everything from classical to rock-and-roll, but probably not enough volume to damage human auditory systems. If I had perfect pitch I could tell you the exact resonant frequency of my computer desk, the floor and the walls …if I can feel the sound as well as hear it that should be loud enough for most listening.
This system is more dependent on software than any other PC audio system I am aware of. As a result the local computer can make or break the Z Cinema system depending on factors that are not under Logitech’s control. My system is a high-end, quad core 64-bit system with 8 gigs of RAM running Vista Ultimate 64. The Windows Media Center software is installed so that is what the Logitech software uses on my system.
This system is dependent on the USB bus unlike other PC audio systems. The USB bus does have some issues that can adversely affect the components attached to it. As noted above I had to use a USB 2.0 port directly connected to the PCI bus in the computer for the Z Cinema in order to avoid conflicts with my keyboard (Kensington Slimblade Bluetooth via USB receiver).
In over 5 hours of constant music play I only experienced one break in the playback and that was before I moved the USB to the PCI/USB port and before I upgraded the Logitech software to the current version, I have not experienced a break in the playback since those changes. I have noticed similar breaks when playing movies on this computer (not recently though) and I suspect the breaks have more to do with the local computer than with the Z Cinema system or the Logitech software.
I have also checked the CPU usage in Task Manager when playing music from a CD. I do not see an increase over what the Window Media Center / Windows Media Player consume on their own, which is considerable in short bursts. I’m sure the Logitech software consumes some CPU cycles but it is not enough to show up on the charts.
