I've got 10t's and will echo the other posts, they need current! I had a pair of Classe' M-1000 mono's that were good, but found nirvana with Levinson 33H. Don't let the "150" watt rating of the 33H fool you, there's MUCH more to them than meets the eye. 10t's will be a mirror of the upstream components. Am I crazy to drive $8500 speakers with $20,000 amps? I think not! Paul
