Here's my standard response...
I've had tubes for years and loved them. I mean really loved them. However, there are compromises I'm willing to make because 1) I want something I can leave on 24x7, 2) I need something that doesn't generate as much heat, 3) I don't want to continuously wonder if a NOS set of Pope 6SN7s sound better than my NOS RCAs or if my 12BZ7s are aging and need to be replaced, and 4) I want hardware that doesn't require as much real estate. Given my wants and my needs (which also includes equipment that does not smear the time domain), Ayre seemed the ideal choice.
I now use an Ayre AX-7e (and I could not be happier).
