1700mA will get you quite aways.
Now, I got this one to power my Volcas but considering the price of the Volcas and the price of this unit it never entered my mind the buy one for each.
But as the Volcas does not draw that much of a current you can actually use just one KA-350 to power 5 or more Volcas with a splitter cable.
Good thing about getting a brand certified peice is that you will not get any trouble with garanties if your equipment fails.
From what I can hear this Power Supply does not add any extra noise to the signal, that is always a risk when mix and matching power addetivs.
Content with my purchase, will get a splitter cable next.
