Panamax Power Conditioner: Keep or Upgrade


I have a Panamax Max 1500 Surge Protector/Power Line Conditioner which I have had in my system for approx. 15 years.
Recently I began the process of upgrading parts of my system. Wondering if I should replace the Panamax due to its age and the advancement in technologies over the time period?
Any recommendations on this?
I am looking for thoughts and feedback on whether the Panamax is still serviceable, especially from those that have experience of this model, or maybe look at other parts of my system?
Thoughts on the Panamax and if majority feel it’s time for an updated model, please let me have some recommendations. Budget to mid-range price ranges. Would like to keep it, as we all would, the best bang for the buck!
Not going to outline the rest of my system, so I get feedback just on this power conditioner question. Especially because it is the oldest piece in my system.
Thanks for all comments and thoughts!

Tripp Lite Isobar Ultra or Furman with LiFT and SMP are in the same price range. I like them because they use big coils to slow down a surge, letting the circuit have time to act.

Since all of these have components that will eventually wear out replacing every 15-20 years is not a terrible idea.

I use Furman for audio and Tripp Lite for PC and other sensitive electronics.

Of course, Brickwall and Zerosurge have a fantastic rep, but also about 3-4x as expensive.
If it`s sacrificial, or has MOV`s( which degrade over time depending on how many instances they protect from surges or spikes ), it may be best to replace it.

Furman, or Brickwall, would be excellent replacements.
Thanks for the responses so far.
Wondering if I haven’t had any issues with the Panamax, Ishould just leave well alone, despite its age?
Anyone had any experience with the iFi Powerstation?
Not cheap (about $500) but seems interesting.

I like the PowerStation; IMHO the best option in its price range. I have several in secondary systems and in the recording studio.

For my main stereo where I don't have cost constraints, I use the Puritan Audio Labs PSM156.
I had a Panamax M5100 for several years. Replaced it with an Audioquest Niagara 1200. Furman is also a good option.
