iPower voltage is 9.3V.

Hi!

I just got a microRendu and an iPower from Sonore.  To check the polarity of iPower's socket, I measure a voltage of it with FLUKE digital meter and it read 9.3V (center +).

mR get a quite warm after an hour of listening.  User manual states that "The Sonore microRendu utilizes an optional power supply capable of delivering 6-9 volts at 1 amp min (center +).  Do not exceed these power specifications or damage to the unit will occur." and I think that iPower's output of 9.3 volts is exceed the power spec. My question is that if it is OK or I should stop using now. 

 

Just for an information,
