New speakers needed on a budget

New floorstanders for less than $800 is a tough proposition.I second all previous suggestions for used speakers(I love the Quads).
Michael at STO Sound and Vision does a great job with inexpensive floorstanders(sold at deep discount).He carries Mission ,Mordaunt Short and Wharfedale floor speakers that look and sound great for much less than your max budget.Wharfedale is made by the same folks that manufacture the Quad speakers.I have no affiliation with STO.

I picked up a pair of Totem Arro's here on Audiogon for ~$800.

Second looking into PSB very good speakers for the money especially at what Johnnyb states above

for your stated needs, in addition to the totem and psb recs i'd look at monitor audio rs6, rega r5 o rs5 or my personal faves, the focal cobalt series, all of which can be found used within your budget. you might also look at accessories4less for discounted canton gle and mordaunt short--both vg.

Used Thiel 3.5's.
