Hi -

I've got an AT150MLX (in a ReVox B791 Linear Tracker) and also think it is a great cartridge. I would do some more work on the loading though to get the most out of this setup. Audio Technica suggests 100-200pF for TOTAL capacitance and I think you would be better off lowering it as far as possible - if you can remove ALL capacitance from the preamp I would do that (I've got 115pF with tonearm and ICs with no input capacitance in the preamp with my setup). You definitely need to consider other resistive loadings going into the preamp (just like with a MC) and I would suggest 220k Ohms and 100k Ohms as two possible values to initially parallel with the normal 47k Ohm that I assume your preamp has. See the answer I posted to OldDude's question about how to do this in last week's posts for further info on how this is done. You may even have to go lower with the parallel resistance depending on how bright your system is - I'm using 71k Ohms in my system but I've got "bright" NS-1000M speakers to drive.

Hope some of this helps, and it really is a great cartridge - enjoy.

  Thanks. Regarding capacitance, I'm somewhat confused by my preamp's instruction manual. Right now, I have it set to 47pF as the "entrance capacity." The other options are 100pF and 147pF. It says that "the entrance capacity without connected capacity amounts to approx. 60-100pF." I'm not sure if this means that the 47pF is in addition to the 60-100pF or if by selecting the 47pF setting it is reducing the capacity.
  
  I'll switch the 47pF switch off and try it there for a while...
