Best used floor standers up to $1300

I would suggest the speakers that sound best to you, are within your stated budget and can be properly driven with your electronics.

Since there are literally hundreds of speakers, used and new to choose from, how could I possibly recommend one? This is the one component that must be auditioned and heard. Suggest you go out and listen to a few new models that sound good to you - then start hunting down used ones that have the same sonic signature, driver design and specs. Once you have put together a short list, then ask for opinions from actual users.

What your doing right now is the equivalent of selecting a vacation destination while blindfolded and throwing darts at a map.

There is a few pairs of Vandersteen 2C's listed here that is in your price range. You should check 'em out!

I appreciate the responses. I have little time and ability to test options, but will see what I can do. Folks' personal experiences in this area are insightful though.
Also, I was actually finally able to locate my earlier post with a similar question I posted earlier in the year (I couldn't figure out how to find my links older than 30 days), so I apologize for the similar posts. In any event, I appreciate the thoughts and responses to this and the other one. thx

There is a new pair of Golden Ear Triton 7 speakers listed for around 1,300.00

The PSB x2t would be an excellent choice. I really liked their predecessors,
the T6. Another speaker you might want to check out is the Bowers and
Wilkins 683 S2. If you can find them used they should be within your
budget and with a bit of a discount new should be close to your budget as
well.

With your large room and high level playback I think you're on the right
track with the PSBs. I was going to demo them but the B&Ws wouldn't let
me leave without them last Sunday.:-)

Good luck with your search. Take your time and enjoy the journey.

Cheers,

Scott
