Upgrade from Spendor SP 1/2, what's next?


I currently have a pair of original SP 1/2's and am upgrading from a Cayin TA-30 to a Cayin a88t to drive them. Listen mostly to classical and jazz vocals and love the sweet mellow warm sound. I'm considering trying a new speaker and was thinking of going to a floor stander. What Spendor floor standing speaker (or other maker) would you recommend? The room is 20' x 14' with 10' ceiling, wood floors, minimal furniture.

Neither are floor standers, but your obvious progression is Harbeth next, then to Audio Note.
Don't know if the OP is still looking but I had the Spendor 1/2E's in my system for about 4 years and they are excellent speakers with really only one weakness - they don't do the bottom octave. Since I listen to classical music (lots of orchestra) the bottom octave is essential for the most realistic sound. I tried and tried to get a subwoofer to integrate but was never successful. So, my upgrade was to Vandersteen 3A Sigs. The Vandy's do everything the Spendor's did in the mids and high (i.e. supremely natural and musical) but add the missing bottom end that the 1/2's didn't render. I've had the Vandy's now for several years with no urge to change.

Or maybe to Reynaud.
