I have the prem 11a and I like it better in the Hi-power mode. I don't like classical only pop & rock so the 70watt setting works best for me. BTW your cables are not recomended for tube amps. I tested MIT 770 and the amp was running hotter than usual. Soundstage magazine recomends against using cables with networks or electronics in them. Read all about it at their site. Kimber Silver cables are awesome with tubes.
