"In the long run an amp like the Raven will have you happy and smiling probably for the rest of your life..."
He meant "until the tube needs replacement, which is just around the corner" so skip the Raven. Which, indeed, could be recommended although not for you in this particular case.
As someone has already said, personal audition is called for and I would also vote for Yamaha. Simply because their (much) lower level amplifier is surprisingly good and I have never heard other two.
