So I recently adopted a Model 500 from another AK'er, and i tried using my Denon DL-103R on my Denon DP-59 on it. Plugged it in both Phono 1 and 2 inputs, and played around with the gain and Impedance settings. I can only get a decent amount of volume out of it by turning the Attenuator switch to the up position and cranking the volume knob to the 12 -3 o'clock position. All other inputs are fine and I haven't tried a MM cart on it yet. So is the Model 500/600 designed to accept MC carts directly, or if you guys are using a SUT what would you recommend that won't break the bank? Any help would be appreiated.
