The best sounding, and best performing for surge protection devices I know of are Furman with SMP and LiFT. I live in a lightning prone area and based on testing done by Wirecutter and my own listening tests I can honestly say I would never run an audio system here without a Furman. Keep the feature list in mind though. They make dozens with a variety of combinations of features but the one's you want are LiFT and SMP.
If you were in a home I would also recommend a whole house surge protector in the electrical panel, preferably one made by the panel maker that fits in place of breakers.
