Default Bridged 4780 with 35V rails

Im planning on building a 6 channel amp with the LM 4780. Im gonna use 2 25V (35V peak) 600VA trannies. Itll be 2x60 watts (for my tweeters) and 4x120watts (midrange and bass drivers). On the LM4780 datasheet on the Output power vs supply voltage, brigde mode graph, the maximum supply voltage is 30v. Is it safe to use 35V rails? Will it degrade sound quality? Are there any disadvantages to using bridge mode over parellel or normal with 8 ohm speakers?
