I see that Anniversary on Audiogon is 220V and located in East Java.
Wrt the huge Teflon caps in the 40, just be aware of potential hard to find replacements; I would talk with ARC before commiting.
Review of Ref 10 with v. brief comparison to Anniversary and 5SE,
HERE.
When you consider the Ref 6 linestage is $14k, either the 40th or the Ref 10 look really (really) good.
