Hi. I solely used tubes, big Joule Electra OTL amps with my Parsifals. A good match. The person who purchased these speakers used solid state amps and felt the match was superb. I did not hear it but he raved and raved.
If it helps, I will dig around some old emails to see if I can find which amps he used.
