Best small used monitors under $1000

Epos Elan 10s or Epos Epic 1s with one of the new Yamaha integrateds would make a great match for that room size. You'd have plenty left over for some heavy, good quality stands, which impact the sound more than you might assume.

I've owned the Epic 2 speakers (larger and probably too much bass for your room) for 4 years and they compete well with most speakers under $3K. Of course, speakers all come down to personal taste, but these Epos models are great all rounders IMO, and don't have any blatant weaknesses. 

Guru QM10-2 used if you can find one. Really fun, great prat. Awesome little speakers. 

Hi yogi, I have a pair of s 3/5 spendors. They sound a little veiled. I have to try with solid state. It might be the speaker itself since I purchased used.

mapman I have followed you journey with the audio note kit and really enjoyed it. What is your current system?

i have minuet supreme plus in the office with a Yamaha rx 777 and like those but was wondering about the quad12l. 

Im more curious about others systems and the synergies. 

Silverline  Minuet, Elac UB5,  and if you are willing to go just a bit over budget, the KEF LS-5o is among the best around at any price in a small room.(That is what I use in my 9x11 room with great results) Any of these could be driven to good effect with modest, but carefully picked out electronics. As you know, when you are assembling a world class playback system at any budget, make sure to select the best source components you can afford. A lousy source will make even megabuck efforts sound not nearly as good as they are capable of..

Let's talk about all the components in the system not just speakers.
