I currently own the Zerius with a Roksan Caspain Int and YBA CD Special....I was curious how tubes would sound with the Zerius so I went back to my local Triangle dealer to hear the Heliades with tubes. I found that the Heliades didnt sound any better then my current set up. I asked my dealer and he said the new triangles dont work as well with tubes. The older 202's worked quite well with tubes. So it depends on if you use SS or Tubes with the new line if you should upgrade. I would go with the Celius over the Heliades it would be a lot bigger improvement.
