Update.
So far I listened to the Krell 400xi, McIntosh 6500 and Musical Fidelity A5. Note that none of the dealers I visited were Totem dealers (I have heard the SimAudio - Totem setup previously and thought they were nice).
So far the Musical Fidelity A5 is the winner. I thought the Krell sounded a little hollow and McIntosh 6500 was nice but couldn't justify the price differential from the Krell ($1000 more for the Mac). M-F A5 sounds pretty good,
it is roughly the same price as the Krell.
I am planning to listen to the Ayre this weekend. Thanks for those who gave suggestions, and I will keep you posted.
