BAT Vk55se or Atma-Sphere S-30 MK111 withal all the upgrades ?


 I am looking for feedback about which one to chose. BAT VK55se or Atma-Sphere S-30 MK111 with all the upgrades to pair with the Tekton DI's. anybody? I have heard the Atma-Sphere M-60 monoblocks which sounded very good, however I do not get the opportunity to audution these as they are for sale used. Does anybody have an opinion about these different amps? BAT vkd5se cup, BAT vk51se tube pre and Tekton DI speakers with upgrades.

Hi, you may be interested to join this facebook group for Tekton Design speaker owners in case you have questions or would like to know more about their first hand experience with them, and the electronics they use to match with their speakers:

There is an 8 ohm version of the DI, which is the one to use with tubes in general.
