You might do a search on this forum for Stan C. (Stanley Chu) and bcherry (Brian Cherry), since they are the makers of Opera Audio / Consonance / DIYHiFi amps, including the Billie. They have tested π speakers on their amps, and have reported that their amps worked well on each model of π Speakers.
