As an owner of a low hours LS-26 I too have considered which would be the right move to make and canvassed the opinion of someone who reviewed the LS-27 and as I do not have his permission (because I haven't yet asked) to post his comments he will remain anonymous. His comments were:
"I have used the Ref 3 but not in a very long time. I do recall comparing it to the LS-26 back in the day and thought the 26 was awfully close. But I did not have one handy to make a direct comparison to the 27. If I was making a choice between a Ref 3 and a 27 I would go for the 27. I do note that AR claims the 27 betters the 3. I can't confirm what is obviously marketing but it is not inconsistent with what I hear and recall."
I also spoke to someone @ ARC and their opinion was to make the jump to the LS-27 Vs a used Ref 3 but I temper, but do not totally discount, that with the fact my buying a used unit doesn't necessarily impact their balance sheet in a positive manner.
Having recently acquired new speakers this matter has taken a back seat in my audio upgrade path and I recently purchased some NOS 6H-30DR tubes for my LS-26 as a stop gap measure which I have yet to install...
