I have had Shahinian Diapason and drove them with Plinius SA-102. Wonderful top end, one of the best in SS amplifiers I ever heard. I sold my Plinius partly because it could not provide the adequate bass and replaced it with Musician III which appear on market at that time.
Check cabling I would add to others suggestions.
Good Luck
Simon
