Changed circ.breaker-vocals became shouty:why?

Hi
I live in pre-war apt.building.The circuit breaker that was feeding my system was an old 15 amp gadget that was long ago discontinued.When i noticed that it was 15 amp i went and bought a $25 30 amp replacement for it.After installing it in the box i noticed that vocals and solo guitars became shouty and flat even though the rest of the spectrum became more dynamic,especially bass.After i put back the old breaker,the sound became 3-D and warm again,even though the system was straining at high volumes.Is it a circuit breaker burn in factor or something else at play here?My power amp is Pass X 250,5 driving 86db/4ohm Snell type B speaker (6 drivers per side,3 of which are 10 inches).
Outlets by PS Audio.Any ideas?Thanks a lot.

Thanks for your replies.
The wire is 12 gauge.I will step down to 20 amp breaker.
The dynamics changed a lot with a 30 amp,a lot of headroom and the lights on my Panamax power conditioner are not flickering on the border of underpowering anymore.But fire hazard is something i don't want to play with.Once again,thanks to your advices.

No,the Panamax if for cd player and preamp only,the amp is plugged into the wall.They do share the same outlet though.
Btw,the Panamax in my experience is way better than the current Monster/PS Audio stuff.As i understand Panamax had several owners in the past 5-7 years,mine is mid 90s model with upgraded cord and outlets.
