The brushed aluminum casing certainly draws your attention. It looks really good. Looks can be deceiving, but it this case, it's not! ;-)
I have used Harley Benton Powerplant power-supplies before...
I used the Powerplant Junior before, also for gigging. NEVER problems. No noise, no hissing, no buzzing..100% silent. No issues at all in 9 YEARS..
That is how good it is.
I wanted to replace it because the powercable is not easility replaceable.. if during a gig the cable has a problem, then you are scr*wed.
I replaced it with the Powerplant ISO-3AC SAG, which has a detachable cable.
The 12V LINK can be used for pedals / preamps too. No noise or other issues with my 650mA preamp.
If you are gigging quite a lot like me, 1-4 times a month, i advice to use the Harley Benton Power Supplies with the detachable cable. Do not use versions that have the 12v wall adapter,, if you want reliablitiy, use the versions that have the replaceable cables.
The price is crazy cheap compared to other decent noiseless power-supplies.. Many 150-300+ power supplies have less isolation/noise preventing measures.. And they are more expensive!!
Besides that, the brushed aluminum casings of the "Harley Benton Power-Plant ISO series" alone should be enough to buy one, quality craftmanship, it's beautiful.
Thank you Harley Benton.
