Is it a series or a ladder stepped attenuator? With a series, the signal goes through a lot of resistors and solder joints. I'm selling a CAT SL 1 III mostly because it uses a series stepped attenuator (as does the Cat Ultimate) and sounds much less transparent than an Accuphase DP 75 straight into power amps. And I thought Wadia's digital volume control was somewhat better than Accuphase's, though I haven't heard it. You should do only a little attenuation with a digital control, if you can manage that.
