I purchased a 5V 1A linear power supply to evaluate the difference between stock and upgraded ps on my SB3. I popped open the stock ps and it seems to be quite well built. The aftermarket ps has a less involved circuitry but a considerably larger transformer.
I am very familiar with the performance of my SB3 and in my system the internal dac of the SB3 is superior to the dac in my receiver. I also use the internal dac on my cd player for my comparison as it performs better as well. The driving force behind the upgrade was a definite lack of detail and depth on the SB3 playing Apple Lossless Compression music compared to my cd player. The SB3's performance has improved to the point that the difference is far less apparent. Detail and depth are improved and most of the difference in the presence is due to the output level of the SB3 being down slightly. I am eager to try an outboard dac to see if I can exploit the SB3's performance even more.
