Refresh Ohm Walsh 4s or Walsh 5000 upgrade?


My Walsh 4s have been perfect for my space, with two REL T5s adding just a tad to tighten the base.  One crossover has finally gone after 30-40 years.  I am choosing between sending the crossovers and cans for a refreshing, or springing for the 4-5000 upgrade.  I read on the recent Ohm Walsh thread a few members have the 5000s.  Has anyone gone from an older Ohm Walsh 4 to the 5000, or had both?  What was the improvement or difference?

thanks

I went from 1980s Walsh 2 to newer x00 series one gen older than current in 2008. Had both concurrently and compared them a/b. Huge difference, no comparison...detail, soundstage,imaging, tonality....better more modern sound in every way. Go for the upgrade if you can afford it.

I currently have both 100 and 5 series 3 driver models.   100s on refurbed Walsh 2 cabinets and 5s on refurbed Ohm F cabs. 
Thanks, mapman .  Good to hear.  I’ll put the upgrade on my old 4 cabinets that are in good shape.  That will keep the cost down.  Never had a desire to see if the grass was greener on the other side or replace the 4s until the one acted up, so the cost seems like a bargain to me.
