High-Power DC power supply upgrade for NAIM amp?


I am considering the NAIM SuperNait3 integrated amp and keep hearing about the High-Power DC power supply upgrade. 

What is the impact of adding the High-Power DC power supply upgrade to this amp?  Is the High-Power DC power supply upgrade a NAIM product or, if not, where can I find it?   How much does the High-Power DC power supply upgrade cost?

Has anyone added the High-Power DC power supply upgrade to this amp and what were the results?   Did you notice an improved sound quality?   Any additional comments are welcomed.   Thanks..

I've yet to find the amplifier, source, or processor that could not benefit from a higher-current, lower impedance, lower-noise power supply.
