The Boulder Cable 5 volt regulated power supply is a recommended upgrade to the SB 3, also, taking it one step further, Red Wine Audio produces a battery power supply that reviewers seem to like. Additionally, there is 6.2 Firmware for the SB3 (I'm not the least bit familiar with it) that one reviewer felt was essential for upgraded performance.
Both Prpixel an Rootmann have mentioned upgraded power supplies that I will explore. Apparently this is an essential upgrade.
