My understanding is that there are some new circuit boards and each DAC now has 2 transformers instead of 1. I was told that in addition to sonic benefits, this reduced heat and increase reliability, FWIW.
The upgrade increases the speed and depth of the bass. It is not insignificant, but it is also quite a pricey upgrade. I would put it on the same order of magnitude as adding good power cords.
