I'll second the Cary Sli-80 recommendation.
I had a Rogue Cronus - not the Magnum - and it is a great amp. It has a lot of fans and you can expect great service from Rogue. I had a Cary AES-25 amp at the same time and even though it was a little underpowered for my speakers compared to the Cronus I preferred the triode sweetness and musicality of the AES-25.
That experience led me to buy an Sli-80 and I couldn't be happier with it. I wouldn't try to talk you out of the Cronus but the Cary is worth a listen in comparison. No experience with the Primaluna.
