I have the 3007 now for 3 weeks and it replaces the 876.
I do find the 3007 to be a better amp with more options then the 876, but also
the 3007 has some disadvantage to the 876 and thats the "clicking" part.
I hear two types of clicking, one loud and one much lower in volume.......
The loud one is the relay click between switching audio settings with the listening mode button on the remote
, never had this on the 876.
The lower volume click is the one that occurs between tracks on the use of the NET port, and between switching sources.
This is a click when the 3007 activates MUTE, according to Onkyo Europe, and can not be turned off.
Also the use of gapless playback on NET is not (yet) possible, this would kill the lower volume clicks.............
Special the clicks when i use the listening mode button are bad, and make you want to stop fast selecting your favorite audio setting
Have no idea why the 3007 has this clicking and the 876 did not.........
I have now a 11.1 setup and tried both WIDE and HIGH speakers with various sources like music, TV, radio and BD.
I find WIDE to most usefull and has the biggest listening "improvement".
Also find WIDE to be a great addition for BD a realy pulls the soundstage wider, on TV with A.C.S. its not so a big differents.
For WIDE and HIGH i use satelite speakers of a surround set and works great.
Its still strange that Onkyo only lets you use WIDE or HIGH and not both as the audio codec is availible to run both with the DSX option
I know we have "just" 9 amps and not 11 but it would be better to split the wide or high amp so we could use both options at the same time.
maybe it will be possible with a future Firmware update
(PS. Audyssey DSX
setting will NOT use the surround back speakers
, PLII DSX
will use the surround back speakers, strange...........)
In my case i will use WIDE for 100% of the time and have the HIGH speakers ready for use when someday PLIIz will come availible on BD.
