As they say, "different horses for different courses". A while back I changed to the older 00044 firmware in my G68. I've stayed with it because that system is 95% video and I like it better, especially for dialogue, than the latest M firmware. On the other hand, when I listen to music with that SBT at first I thought I was hearing more high end detail but after extended listening I find it fatiguing.
