I upgrade to a G68 few months ago and once I opened the unit to upgrade the fuses for HiFi-Tunning I took a look at the psu to replace the caps but I just decided to upgrade the whole psu, to be sincere the new fuses are necesary especially to those ones who want to avoid the hassle, the G68 was more revealing, the bass is tight and you will start hearing sounds you never heard before.

I upgraded to a more powerfull psu with better load regulation and it brings the G68 to another level I also recommend to upgrade the internal power cord to obtein better results.
