I have not heard the Ayre but I know people consider the 20 reference caliber. I will keep any eye out for a used unit since I have not bothered a dealer with an audition for that one. I have no problem buying used but not if I demo the same gear at a dealer.
You were correct in your assumption about tubes for the reasons I mentioned above and also the heat factor in my corner room that gets hot in the summer. I spend 8 hours+ a day working and listening to tunes in there. So cooler temp equipment is important. I also have 7 thin computer screens in this room too and they give off heat right into my face. Only 2 silent computers though.
Anyways, the list of preamps that is compiled here is really awesome.
