Hi Carl,

I've also heard that some people have added/increase toe-in to compensate for the effects that the new DSP firmware/EBA has on their system.

I already have toe-in on my speakers and they have 'not' been updated to the latest firmware/don't have EBA.

My ears tell me something is different in my system with just the 818 firmware update.

I was not expecting any change in sound with a processor update, so no psychoacoustic demons at play here smile

To bring the sweetspot back, I have to do the opposite... 'reduce' the toe-in or move the speakers closer to me or move my seat closer to them.

As I listen to my system everyday, it was obvious straight away.

Just highlighting the fact that even processor/source firmware updates are worth doing separately to DSP firmware updates... just as a precaution to eliminate unknowns.

Everyone's systems are different but this is what I find in mine, so just feeding back to maybe help others. This may have similar effects on other items that are due firmware updates.

Still a very happy listener smile
