RLeff, I have been listening to the Joules for about 3 months without a dedicated line. They sound terrific - paired with the Joule preamp, I could not be happier. I am still considering installing a dedicated line, though, because they seem to get only just enough power. The Joules use a variac. I have to dial up the variac almost to its maximum point (and sometimes to its max) to get the amplifiers enough current (the amps have a readout that lets you know when you are at the proper point). I have not made the time yet to contact an electrician to see if the installation of one or two dedicated lines (20 amp as suggested here) would do the trick. What has been your experience with the panthare's? Regards, Kevin
dedicated electrical line
I recently read somewhere that a dedicated electrical line is recommended for some tube amps because of the amount of current they can draw. I have Joule VZN 100s on the way. My home was renovated about 10 years ago - new electrical system was installed at that time.Should I be concerned - not looking forward to trying to explain this one if a dedicated line needs to be installed.
