I've never tried the 12's. I have WBT locking banana's on the ends. I'm shure the T1 spades would be a pain. I'also have 3.6's, but use MIT 770 & 770 tube in an active bi-amp set up.
VTL-IT85 or Classe CAP-151 for magnepan MMG
I am currently using a Classe intergrated with my MMGs. Although the Classe has plenty of power I do find it a little flat, ( maybe lack of tone controls? )remember hearing VTL450's with the 3.6's and was blown away. Considered swapping for the IT-85 for a little more warmth and better soundstage. I've tried placement all over the room and Im using analysis plus oval 12's. Room size is 20 x 24 and a little bright. Any comments or suggestions would be welcome. Thanks, John
