CAB1 for conventional engines - any improvement?

I have one loop that has a Powermaster attached with a ZW as power. It "seems" that the Lionel and Williams conventional engines operate a little better with the Cab-1 control. A bit slower, a bit more precise control. But, I don't have measurements or data.

I used a CAB-1, PowerMaster, and MTH Z750 with my MTH Railking RS3, NW2, Atlas/MTH GP9 hybrid, and Willaims E7 before getting DCS and they ran fine.  They ran a bit smoother and slower (easier to control) than using the Z750 control knob alone, but with DCS and TMCC I got better slow speed (finer speed steps) control.

Now the 3 units are sitting in a box.

I am not sure there is an advantage to using a cab1/Powermaster if you have a modern transformer but there is if you have only Post War transformers. Most of them start out at around 6 volts. The powermaster starts at zero volts plus will give both whistle and bell control without a separate bell control.

Sounds good. Slow speed control is important since I have several operating accessories where it's important to have the car lined up just right (the horse corral being a good example). Right now I have a CW-80 and a MTH 100 watt brick/Z Controller powering two different blocks. Like to use the CW-80 as a dedicated accessory controller and the MTH to provide track power. 

With the CAB-1 and PowerMaster, I think you only need to connect the 100 watt brick (no controller).  The Z750 puts out 22VAC but I think the Z1000 puts out 18VAC.

I later found out that Lionel and 3rd Rail doesn't want folks using more than 18VAC on TMCC engines so I ended up getting a Lionel 180 brick to replace the Z750 brick.

My brick puts out 18VAC so no worries there. Would need a way to convert the MTH brick plug to fit the PowerMaster unless I routed it through the Z Controller. 

The PM-1 is 32 speed steps.

Lionel has an adapter plug that fits into the Power Master and has a regular terminal end for transformers.  It also has an inline fuse.   G
