I have asked nicely for you to act like an adult. I don't know what you think that childish post does to improve your standing. I am not hear to play in your personal circus and jump through hoops for you. When you have some ownership position in this website I will reevaluate that. Till then.
The "op" has put out a few tests. Only one was a technical question about speaker design. However, if you would like to argue about imitating tubes. The op has a preamplifier that uses tubes, and an amplifier with an input stage that is tubes. The output of his amplifier is solid state. Its damping factor is about 10-20x what the damping factor would be of a tube amplifier and 20x that of the Sunfire in tube emulation mode. The OPs speakers are very low impedance. The Sunfire in tube mode would make a mess of the frequency response in a system the OP otherwise likes. That, in my books, is a terrible and poorly researched suggestion. I know my limits and admit them.
