The new Rowland Power Storage Unit (PSU) is a full chassy external ultra-capacitor-based power supply. It has been designed to power simultaneously up to three line-level devices... A Rowland Aeris DAC, a Corus linestage, and as one spare output for future use.
I have had it in my system for about three months, and have applied it to my Aeris, as I am not currently using a line stage. The enhancement that PSU has brought to the system is rather phenomenal, for all audible parameters I can think of.... Its effect is tranformational: more in line with a substantive upgrade of all electronics, rather than the replacement of just one power supply.
