ADS L 520


I have a chance to purchase a beautiful pair of ADS SL-520s for $50 for the pair. I am currently running a pair of mid 1980’s Klipsch Heresys with a low 2a3 powered tube amp. Any opinions if this would  be a improvement or a downgrade from the current heresys that I am running now. Thanks.

I still run 520's in my upstairs AV system. Great for movies, etc. $50! Go for it. 
i still run a pair of l520s in my basement and love 'em--very resolving tweeter and great bass for such a small speaker. also very efficient and easy to drive--as stated above they're a different animal than the heresy, but i'd grab 'em for $50
keep them both and educate your ear !!! they are cats and salmon different and both have manifest strengths..

but Lord, please dont stack them on top of each other...
