Noticeable Sound Improvements With Speaker Re-cap?

Hello!

I own a pair of Infinity RS 4.5 speakers. I drive them with either a Krell FPB 600 or a Sunfire Signature 600.

Right now, they sound near perfect to my ears.

I keep reading in multiple posts that a re-cap will take them to the next level.

They are over 40 years old, so they are definitely due for new capacitors.

My question is this, for anyone who has performed a full re-cap on their speakers, what were some of the most noticeable sound improvements?

Thanks in advance!

On my IRS Beta ALL Solen caps were totally off spec or totally dead. All TI and Wonder caps measured perfectly. I replaced with new Solen to maintain a level of originality. LEMIMs and EMIMs came to life. Big change that I had not immediately noticed due to the gradual deterioration of the capacitors (and of my ears). Back to normal now and fantastic
