Are the Paradigm Founders 100F a big upgrade over 85F's

I am not familiar with that model but I do have several pairs of various Paradigm speakers in my home theater and they do offer very good and musical sound for a price lower than expected .  I would definitely do a good listen to them.  

We are long time Paradigm dealers yes the founders series is a huge improvement over the 85s. 

the founders have a cleaner treble with less splashy high end the midrange is smoother and the drivers integrate better,

the founders image better andhave a tighter low end as well

in particular the 100s are the sweat spot of the line

@audiotroy if it was just up to me I would do it. My wife thinks our system with the 85F’s and 55Cis amazing. She is going to have to hear a big difference to agree. Thank you for your comment 

she isn’t wrong the 85s can sound amazing if matched with the right gear the founders are definitely a large step up in the areas we indicated

@audiotroy Thanks for your comments, I will be having an audition later today

I hope you update us on your wife's comments after a side by side comparison. I know I lose some objectivity over the excitement when it comes to upgrades. Inclusion is incredibly worthwhile and can make all the difference going forward.

All the best.
