Spendor SC3, also. I have a front trio consisting of the SP3/1p and the SC#, and the sensitivity and flawless coherence of this grouping was PERFECT straight from the get-go. Extraordinarily natural!

Try KEF Reference 100.

Its neutral, not bright like Thiel, 6 ohm impedance, bi wire. Supurb for voice, and a big % of HT is dialogue.
Don't know what the impedance of your speakers are or what
you are using to run them, but the Energy AC300 which came
out several years ago is a GREAT-SOUNDING speaker. I'm
using it as a center with Thiel 1.5 L/R with Analysis Plus
Oval 12 cables. The clarity and soundstage is fantastic!
It does have a 6 ohm impedance. Used to be an Editor's Choice on audioreview.com.

Good luck.
