American made separates stack from David Hafler — the man who founded Dynaco. The DH-200 power amplifier delivers 100 watts per channel through lateral MOSFETs with zero current limiting in the signal path, which is why owners routinely compare it to Naim, Mark Levinson, and Nakamichi amps costing many times more. The matching DH-101 preamp has a discrete-transistor phono stage measuring an absurd 0.0006% distortion — "zero coloration" is its reputation — with TWO phono inputs, dual tape loops with dubbing, and tone defeat.
Condition and Service:
The DH-200 amplifier was fully serviced by my tech and is 100% ready to go. Both pieces fully tested — every input, control, and output verified. Massive side heatsinks, dead-simple signal path, built like industrial equipment.
Why these matter: the MOSFET outputs are self-limiting (no thermal runaway possible), the amp is stable below 4 ohms, and the whole stack was designed for decades of service. This is the affordable entry into genuine audiophile separates — real power for demanding speakers, an upgrade path (swap either piece later, or bi-amp), and a phono stage good enough to build a serious vinyl rig around.
Killer match for power-hungry vintage speakers — big JBLs, Klipsch, AR, Polk. Spec/service sheet included.
