Thank you, It is an integrated, so is it important to have sources turned on before amp? Also, it is quite amazing the detrimental effects it had on sonics.

Without looking at the schematic, it's hard to say much. Caps at the input on a solid state amp may be there because the first transistor driven has bias at its base, and that bias voltage is unwanted at the input.
If you have a FET at the input, this is less likely to be a problem, and even a standard BJT on a split rail can be set up for 0V on the base.
Most likely, the cap was there to block incoming DC, which is why removing it isn't super detrimental. Since you have an integrated, just leave the volume control down if you're powering sources on and off and you should never have a problem.
Sometimes safety does come first. It was an engineering compromise that a cap was put there for a reason! Sonics aside.
