The GS PSU1 is included as a component of the more expensive version of the GS Solo (the less expensive version simply uses a different power supply), but, as this picture shows;

it looks like the 'tip' of the connecting lead would fit into the power-socket of the GS Voyager portable amp.
I was thinking about getting one of these as an upgrade for the GS Voyager - albeit a rather extreme upgrade, as this power supply will cost only $20 less than the amp itself(!)
Of course, if I did this, I could later buy the cheaper 'entry level' version of the GS Solo without the PSU1...
Has anyone taken a similar approach, does it work well, and does the PSU1 offer any sort of sonic improvement to the GS Voyager?
Thanks in advance for your input!!
