Thank for the advice, Johnnyb53. I currently have a Jolida 302b and think its a great way to get into tubes!
Mechans, it's not that I find the NAD lacking or wanting, I just have no basis of comparison, thus can't determine if this is worth pursuing in my price range. Getting a loaner from a local shop has not been an option (boo). I will definitely look at the Graham PP when budget permits. Thanks again.
