Advice from Audiogon family - best speaker $3k-$4k

I know that you want a floor-stander, but you really should check out the Joseph Audio pulsars, which you can get used, often with stands, for about $4K.  They are truly excellent speakers, with a silly amount of bass for a stand-mounted speaker.  I had a pair and loved them.

this one is easy.    a top $2500 speaker with a $1000 sub.  People sell things like a a pair of F206 REVELs, mint, used, for $2500.   add a REL, SVS, or JL sub, and you will have a FANTASTIC FULL RANGE system

For a nominal investment of no more than $1000, look for a pair of PSB Stratus Gold's (not the i's, however). They will sound like a speaker costing far more. I have a pair purchased by me in 2006 and I will never part with them in the event that I put together a non-reference listening room. I have compared them to the following in my system,

Vienna Acoustics Liszt-No bottom end whatsoever 

Any B&W product-Far too bright and fatiguing

Focal Sopra II-Great mids, but not enough low end

Sonus Faber-Looks good but not exciting from a harmonic perspective

Tekton-Only if the lights were off, as they are not easy on the eyes

Save some money and hunt down a pair!

You may be able to land a pair of Maggie 3.7i used or the 1.7i with a good sub would also be worth auditioning.

Good luck happy listening.

What about used ATC SCM 40s?
