MIT, is the most controversial audio product to date! Some will not trade it for anything, others will "despise" it! Neither group is right...or wrong! T-2, are as good as any cables, at the price range! The amps you mentioned are, as you said, "laid-back" and, that characteristic along with Mit cables WILL-NOT sagnificantly influence the over-all sound! But you Pre-amp will! If you would to GREATLY improve your sound, more attention should be spent on the pre-amp! Regards!
