Cary Audio SLI-80HS vs Primaluna Dialogue HP or Evo Integrated Amps

Greetings all...  I ready to move into the tube integrated two channel world.  I've never owned tubes before but I've always been enamored with Mac stuff and recently heard the Rogue Audio and was hooked.  I have done a lot of research and have narrowed my choices down to these two amps.  I live in Va Beach, VA and don't have access to them for an audition so I'm buying 'blind'.  I've read many reviews and watched many videos (Kevin Deal is quite the salesman!) but was hoping to get more input here. I doubt I'll find many that have compared the two directly but I thought I'd try.  Does anyone have any input here?  And, I'm slightly concerned about having to bias the Cary.  Is this something that I should be concerned about / is it difficult / time consuming?  Thanks for any input.  I appreciate it!
