Where's My Bass?

Actually, I don't like a lot of bass; I listen mostly to chamber music, acoustic jazz and folk. But my Audio Physic Tempo III's are putting out almost nothing. These speakers are by nature light on bass, but mine seem lighter than others I've heard. Otherwise the speakers sound absolutely marvellous, and I'm extremely reluctant to go to a sub (many frustrating past experiences)

I've tried various cd transports/players and a few cables. Should I move on to the preamp and amp? Is there anything in my current gear that jumps out as a potential weak link?

Thanks all.

Current set-up: Musical Hall MMF used as cd trans; MSB Link III DAC; Audio Research LS-7 pre; Pass Aleph amp; Harmonic Tech interconnects; Analysis Plus Oval 9 speaker cable.
