Best way to spend $1000 on used bookshelf speakers?

 LSA-10 Signatures seem to be mediocre speakers, with the price constantly dropping, and very little demand for them. I have done a lot of research and legwork and I found nothing supporting the hype.

But of course it's a matter of taste and equipment too.

I’m with you guys on this one. OP, I think I paid $1400 for my LSA-10’s, and I consider it to be money well spent. $999 is almost a no-brainer, and they’ll have that bass punch you’re after. I listen to a lot of electronic music and they don’t disappoint in that department.

Just out of curiosity, did your “research and legwork” involve actually auditioning the speakers in your system?

Never heard them but lots of love for Fritz products.

Dyna A25 or A35.  Still a huge bargain even after 50 years.

OF COURSE I DID
I bought them for $1300. 
I contacted all the raving online reviewers, many times, NOBODY responded. These were the web sites and dudes, quoted for great reviews on the LSA web site.
Listened to them with a number of setups, they sounded awful, whichever way I tried. My PC speakers sounder better.
I couldn't return them so I tried to sell them. 
They were full of scratches on the bottom, - how I received it,  so I spent $150 with a furniture guy to fixt it. 
I then sold it for $800 7 weeks later plus shipping, so I lost $700 not including money I spent on advertising, gas, my time, etc. Then it would be closer to losing a $1000 on a pair of $1300 speakers. Did I mention I took them to 3 nearby audio stores and tried to trade them in and they said: dude, what's wrong with you, nobody knows these, nobody wants these, get out of my store.
I spent 20+ hours trying to sell them including driving 4 hours to meet potential buyers, so it was my worst experience "buying and selling". 
Not that I bought them thinking I would sell them, I wanted to like them. I was told that $1300 is a huge discount, "they are really 
$4000 speakers"
So... after my wife nearly kicked me out for throwing out $700 the window, I DO think I did a lot of legwork and research and suffering.
