Unfortunately I have not been able to listen to the SF Amati’s with any Pass products. However, I have listened to the speakers with several different McIntosh pre amp and amp separates as well as with the Diablo 300 integrated. I was so impressed the Diablo 300 and Amati combination that after an in home demo, I purchased both the Diablo 300 and SF Amati’s 3-4 years ago. I still really enjoy this pairing and I have not listened to anything since that I would consider an upgrade of my current system.
