I was about to order the Magni 3 for my HD650 and spotted this....! back to square one again because i love the tube sound and this will be something i will be buying for years to come. Do you think VALI 2 will be a better pairing with HD650? is it even a good pairing at all...? also if you are a user, let me know if this gets super boiling hot as well!!! not good to be used in a hot country. Magni 3 on HD650 or Vali 2 on HD650 Thanks a lot headfiers.
