I have a Topping TP30, a a TA2024 based Triapth amp, which is attached to some JBL control ones. At the moment, after it's been on for about 20 mins the amp "pops" twce then the volume gets louder - am I right in thinking that this indicates a problem? I haven't used it for about 6 months so cannot remember which volume it was originally. The pops are definitely new though!
Any thoughts appreciated.
