Had the new firmware in my G68 and DSP5500HC for about three weeks now. All listening done without MRC, all speakers set to large with no protection, the levels were recalibrated to 83dB.

It has taken some time to get used to the new sound and for the first week I was definitely not convinced. I detected a scratchy overtone on centre channel voices, especially with DD sources, that I am now not so sure exists. Solo piano has also so far disappointed.

What I do hear is much more separation between sounds and more rounded sounding instruments, especially plucked guitar. The top end seems brighter but with less bite, a plus with the B&Ws. But most noticeable of all is the bass which is now really tuneful and seems to go much lower. Van Halen's "You Really Got Me" (from an LP source) is remarkable, "Internet Friends" by Knife Party, played from YouTube, (recommended by a young friend) is terrifying and tonight I experienced the film Inception which seems to have the longest, loudest and deepest explosions I have heard.

On balance I think the new software is a worthwhile improvement.

In the spirit of Spinaltap, I would like to confirm that I am not involved in the corrupt theft of a global sport.
