I am using Spatial Audio M3 Turbo S with a 30 wpc Class A Luxman Integrated amp. I like to listen loud at times, and the 30 Class A watts sound sweet. I would have to assume the Pass will be ok into 4 ohms, otherwise the Triode Master M3 by Spatial could be the ticket.
Another great pairing I have had with the 30 watts of class a power is the Legacy Focus SE with the AMT tweeters. Really nice too.
