Replacing the linear elements with switchers means more noise in the power lines. How much more, and whether it’s noticeable or tolerable will be down to you.

The linear regulators are still there. It’s the rectifier that gets replaced. I guess the main difference in the power side is the high frequency noise of the switching PSUs vs the low frequency ripple of the rectifier, I’m not 100% sure if 7x12s are immune to them at least at audio frequencies.
