I've listened to the Jolida 502 and the Primaluna Prologue 2, but not side by side. I think both amps will be able to drive the Totems. I listened to the J502 with Maggie 1.6s and the P2 with the Audio Physic Virgos. Neither speaker is terriby efficient. Despite the power ratings of the amps, the P2 seems more powerful than the Jolida. Some of the posters above assume that all watts are equal. The quality of those watts will also make a difference. Both amps are very good, especially for the money. As noted, the P2 has better build quality. It's easy to use for the first-time tube user and should put out great music for a very long time. Based on all my auditions, I think you would need to spend double or triple the price of the P2 to get significantly better sound. I ended up getting the P2.
