RTi12 AMP - Adcom Question

Options
I am looking to pick up a pair of RTi12's from the Polk ebay store - with new 5 year warranty ($799 for the pair). My question is will my legacy Adcom 5500 AMP (200 Watt per side)/ GTP-350 Tuner pre-amp be able to maximize the performance of these speakers? This is just a 2 channel music set-up used for vinyl with a high-end turn table and reference CD player.

If not what would a recommend AMP/Pre-amp set-up be in the $2000-$2,500 range?
