Just reached the fifty hour mark on a pair of 6005W tubes in my Moreplay. The 6005W is the military version of the 6AQ5. They have a lighter sound than the 7C5 or Reflector 6V6. Bass is nicely detailed but not as strong. Midrange is great. The highs roll off nicely. As with the other tubes, great separation between the channels. In the coming weeks I will try 6AQ5 and report back.
