Audio Research SP9 MKII to MKIII Upgrade


Has anyone done the above upgrade to their Audio Research SP9 MKII preamp?

Were you happy with the results?

Were the improvements significant enough to justify the cost?

Apparently ARC can also add a remote to the SP9 for about $700. Ouch!!!
More curiously though is how well the SP9 mkIII or modded version would compare to say a newer sp16 or the like. It seems as though modding or upgrading is really pricey and there are quite a few newer models available on Audiogon for less than the cost of the mods.
I'm asking because I am considering an SP9 myself.
