Which tubes do you have in the Primaluna now? Have you considered swapping them with something else?
But if looking for something new check out the Octave V70SE/V80/V110. Make sure to add a black box or super black box. The latter would be better with your speakers. It really lowers the noise floor and increases headroom.
