Normally DAC's are not demanding in terms of current requirement (unless extremely old). Hence I recapped only the electrolytic capacitors related to the power portions on the PSU board (not shown) as well the DAC board. The caps in question are the five from the bottom half of the board - up to width of the two sets of ribbon cables.
Once done, the good ol'bass was back!!!

The 606 has no standby mode since it was designed to be left on for optimum performance.
