Dunlavy SM-IIa - Experiences?

Years ago I had a pair of Dunlavy SM-1 which I stupidly sold. Many monitors since and i still miss that sound. The SM-1s are nearly impossible to come by, but I've been in contact with a gentleman here with NOS Dunlavy SC-IIa. He is selling them for $900 each. Does anyone have any experience with these monitors? Are there any differences between the speakers John sold and these that were post John? I listen to alot of acoustic music and female vocals. Any suggestions for current models that compare soundwise to the Dunlavys? Thanks in advance for your comments.
