Stereo vs Multi-Channel Stereo
Have the 4520 for 2 weeks now, coming from an Onkyo TX-NR5007, and briefly TX-NR5010(returned due to faulty HDMI AGAIN). I have 9.2 setup with KEF IQ90 fronts, IQ 70 Surrounds and Wides and IQ50 for Surround backs. Subs are 2 x BK XXLS400.
Multichannel sources sound great(movies and concerts), with nice tight and full bass(love Sub EQ results).
For 2 channel music sources I was looking to use Stereo mode or the Multi channel Stereo mode...
Multi channel Stereo sounds ok, but the levels are high(had to reduce with-10 source level) vs other modes and Stereo(incl pure) modes. Stereo mode sounds very "thin" and just does not sound as if the IQ90's together with the subs are delivering to their full capabilities. With the Onkyo I did not have this difference, and actually liked the stereo mode. On the Onkyo the multi channel stereo was also nice, with the little difference being as if stereo is just output over more speakers.
I tried different x overs, Large, LFE+mains, etc... but I just can't seem to get a full sound in stereo mode, whereas the Mutli channel stereo mode, just fills the room with dynamic rich(a little too) bass/mid/high filled sound.
What are your observations with Stereo mode vs Multi channel stereo? Could it be that the KEF IQ90 fronts would come out with better Stereo with a separate power amp?
