The brighter upper ranges of the G91/G68 have been commented on by several posters to this board.

I only find it annoying on a few CDs, my DVD audio discs are fine. I wasn't able to audition the G68 on my own setup and it didn't seem as bright during the dealer's demo. It may be a characteristic of the upsampling alogrithms, but I'm guessing.

I personally don't believe audio equipment will 'break-in' to make a signifcant difference to this attribute of the sound quality. (I realise this is not a view held by all contributers to this board!) My G68 still sounds as bright as the day I received it some 4 months ago and trust me it has quite a few hours on the clock.

I suggest you play with the DSP presets until you find a sound you like (or sell of it course).

Happy tweaking
