Opinions On Used Speakers music only $5K $6K


I'm looking for opinions on a pre-owned/demo Speaker purchase between $5K>$6K for an all-Krell-music-only- system installed in a 26'Lx20'Wx10'H sitting room with good acoustics. I've used N804 & N803 with good results (detail/imaging) but feel that I need larger Speakers to realistically fill this room. I have auditioning access to Krell, Revel, Wilson, B&W, Focal & Sonus Faber. My first reaction is to try to purchase a used pair of N802 or 803D. Any other suggestions would be greatly appreciated.

A used pair of Wilson Watt Puppy 3-2 at about $4000, or 5.1 at about $5500 are great speakers that will be better than the B&W N802.
Who is the kind soul that lets you audition so many different brands and purchase from the internet?

The Watt/Puppy 5.1, Revel Studio & N802 are among my top 3 picks. Should the Krell Resoultion 2 be considered in this mix? Are they sonically comparable to the above? The downside to the W/P 5.1 is that they're getting a bit old by now. I could get the Revel & N802 @ a couple of years old.

My Amplifier is rated @ 200 wpc.
Access the auditions and PERHAPS consider Merlins,many paths to salvation I'm told,good luck,Bob
