Time to make a decision on int amp


Currently have McCormack DNA 0.5 and Accurus LS11 and want to go with an int amp. I want to purchase from a local dealer and my choices are: Mystere ia21, Rogue Cronus Magnum, Cayin A70T or staying w/SS and do the Musical Fidelity M6i. Speakers are Spendor A6's. Thoughts please!

Unsound: Ironically yes! I was able to borrow the Luminous Technology (Axiom) from Tim Stinson. My concern is that the McCormack is 13 years old and I am ready to make a change and would prefer to try tubes.
