As with ANY solid state (and tube) electronics, there is always a "break-in" period in which the electrons of the metals in the circuit settle. But I doubt that any break-in period will solve your woes. From what I have seen, an upgraded power cord will serve you better than any conditioner, especially for amps. Unless the manufacturer recommends using a conditioner, then I would steer away from them. Exception: PS Audio. But not for amps. They just demand too much current quickly to have any real positive benefit from a line conditioner.
Break in period for power conditioners ?
Is there a break in period for power conditioners. I just put a Monster HTS 2000 in my system. Now it sounds thin and bright. Will this change? If there is a break in period, how long is it? Interestingly my TV looks better but my stereo sounds like .... it needs a doctor.
