Might be more tempted by the Denon than the Technics to be honest. The PMA-350SE had a very good write-up as I recall, quite a dynamic amp. Can you find anything for the 355 online, old reviews, etc?
EDIT: Apparently, WHFS&V said it "could really turn on the thrills" in the Dec 2000 edition. According to the Superfi "discontinued gear" site.
