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.

@blindjim thank you for your thoughtful response about each of these amps. I have made the decision to go with the BAT because A) brand synergy, B) The Atma M-60 monos, although beautiful and detailed were slightly thin in areas, less body, or"meat on the bones" as they say. C) Less fussing around with tubes and fuses, and of course this was the S-30 so even less power there. I think both companies are great but so far I like the overall sound of BAT and I am hoping that the 55 has nice transients, open space around instruments like the M-60 but with more weight. HA, we will see . 
Best, Greg
I think the Atma-Sphere would add more speed, more transparency and larger sound stage, all of which I am told the Tektons excel at.

Not a dealer for any of the mentioned products but have experience with the amplifiers.
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.
