I suppose you could use Mark Levinson amps and preamp, because that is what Harman uses.
Levinson is expensive though. Their cheapest amp starts at $8k USD.
McIntosh is good but slightly expensive, not as much as Levinson though.
There's also Pass Labs, which I like because even the A/B models run Class A. But they get hot! Price wise, it's all over the map, ranging from $5k to $80k
A cheaper alternative that many like is Parasound and Bryston. Even cheaper (but not recommended by me) is Rotel.
I talked to a JBL engineer via the Synthesis customer support email, and he recommended 300 wpc or higher for my S4700s.
