Recommend a budget floor standing speaker less than $1,000

My (perhaps soon to be selling them) Silverline Prelude "D’Appolito array" masterpieces. Sublime tone and they have the ability to make you a better all around person. In fact, I can guarantee that. They're only under a grand if bought used.

I have same Silverlines as well and good they are .
However a pr of single-driver Gallo A’divas on their unobtrusive floor stands are better and less money . Get a small sub, Gallo if possible , and won’t do much better under 4-5 K . I paid $ 700 for both .
Single-driver no crossover so phase / time correct, 100 watt Belles Amp drives them fine .

For $1095 a pair take a look at the Omega   Super 3XRS floor standing speakers. Highly efficient at 94db and fast proprietary full range speaker. Many great reviews.

Funny, I just gave away my Omega Super3XRS to a young couple who loved classical music but couldn’t afford a system. I also gave them my Eastern Electric 8 watt tube integrated which was the only amp of the 5 i had on hand that made them sound good for the simple reason they need tubes to dance .
I also gave them a nice leather coach to put in front of them as they require sweet-spot listening .Also gave them a pr of expensive Mapleshade floor stands which the Omegas really needed as well .Rest of system was old Sony CD and Sony tuner which were $5 a piece at Goodwill and they both sound fine .
My Gallo A’diva TI sound  better and are not fussy whatsoever.

And no, this is not a joke, really happened about a month ago.

I will second miketauson’s comment on Vandersteens. I currently run Vandersteen 3A’s, that I was lucky to get at a grand. Prior to that, I had the 2C’s, which easily fit in your budget. There was a comment about nil difference between floorstanders and standmounts ... I couldn’t disagree more. The best standmounts I have had in my system were Quad 12L’s that on certain material were amazingly good for the $550 I paid. But it is impossible to expect the bass output from a speaker that size can match something like Vandersteen 2C’s or 3A’s. Before I bought my 2C’s I went to a boutique shop in Seattle, where I listened to some Epos, Rega and other speakers thinking that if I bought new, I’d get better quality for my money. Under a grand, I personally haven’t found anything. Trust me, if I could find a smaller speaker than my 3A’s that would give me the sonic pleasure they do in my space, I would swap them out in a minute. Hasn’t happened yet.

If you don’t normally play your music really loud, you can easily enjoy smaller speakers. Consider A/D/S, Boston Acoustics or Infinity? I had some Infinity RSM's (Reference Studio Monitor) that almost kicked my Vandersteen’s out ... it really depends on your system, the amount of power you have, the type of music you play and your room size. Boston Acoustics A150/200/400 are very nice and architecturally mid century modern cool. Sound nice as well. Also, the BA T830 is typically a very nice lower price speaker that in a smaller room would be really nice.

My final comment on Vandersteen’s is this. Richard is a smart guy and designed the 2/3 line to be forgiving with many different sources and still sound impressive. My setup has two Parasound HCA-1500A amps in mono driving the 3A’s ... my brother-in-law is enjoying his 2C’s with a Pioneer SX-850, which I had my doubts would sound good ... and he loves them. They sound nice.
