I'd call the P/Es a "modestly difficult" load. Low power amps in general need not apply and OTLs and SETs should be chosen with care - many will have a rough ride. OTOH, some of the brawnier OTLs seem to be a very good choice and, as I noted earlier, the big Cary 805s are an example of an SET amp that works well.
General rule with the P/Es: If you're thinking exotica, proceed with caution.
Good Luck
