The XA30.5 is not the best option for Wilson Audio. Because they have a fast response. They work better with more amperes. I have owned the XA30.5, XA60.5, XA100.5, X250.5 and now the X350.5.
When you use a Purist Audio limited powercable the X250.5 will have a totally different sound compared during using another cable.
I always prefered the XA series, after I bought the Purist Audio Limited Edition it changed my thoughts. Because this powercable brings the mid fre. to a whole new level. Like your X series amp is sounding in the mid freq. like a XA series amp.
