Isolation transformer - does it offer protection


Say I have an isolation transformer "isolating" a sub panel and then a few dedicated circuits from that sub panel to a listening room where all audio equipment is connected to these curcuits.

Does the isolation transformer help protect equipment from power surge/spikes. If so, why. If not, why not.

Thanks to all with the technical background to help with this question.

FYI, the discontinued PS audio ultimate outlet used a balanced (balun) isolation transformer plus filtering that works well to reduce noise-- it also claims to stop spikes, but I have no way to test. Keces also makes a high end iso sold through ebay-- looks well made.
