Always liked the looks of the DH-101. It's a bit more like the later Dynaco preamps to my eye. IIRC, I never had a Hafler preamp, though I did like my DH-200 power amp. Pretty sure I paired it with my B&K Pro-10 MC preamp but I've had drinks since then. That was the last step before the Counterpoints for the home system, though I used the B&K and a Parasound 750 amp in the system in the photogrpahy studio.
