Which amplifier for avalon Radian?
Sonic frontiers power 3 or Jadis JA 80?
Without a doubt, the JA80 for pure music enjoyment unless you are really into heavy metal or rock music. Some people might tell you to listen for yourself but I don't think you need that kind of reply here.
No you really don't have to listen for yourself. If you can lay hands on a JA 80, gosh, grab it. Use good KT 88's and if you want more slam, try KT90's.
