sds powered on constantly???

I have just received a vpi sds and wondered if it is better to leave it powered on all the time as I do with the rest of my system or just power it up when I want to use it. When powered up I use the tt motor to switch the platter on or off..........
i was under the impression that you were supposed to leave the turntable motor on and turn the sds on and off in order to start and stop your analog rig. i guess you can turn everything on and off as you see fit though.

*Mine is 16"W x 3.75"H x 9"D

*Definitely a sonic improvement with my VPI Aries2 ext. w/ 12.5 arm. Immediately apparent with the first record played.

*I suppose you can keep it running All The Time, but I doubt there's a sonic reason to do so, and one advantage to using the SDS as the motor on/off switch is that the SDS can also be used as a reference to how much time is on your cart-as long as you're consistent about turning it off after every listening session.
I confess that I got my Aries and 12.7 arm at the same time and have not been motivated to audition it with and without for lack of a listening panel to help evaluate the difference. Just getting up and taking it in and out is enough to distort my memory. My firm conviction is that it is a considerable improvement, I did run the Aries for a little while without it at first. I thought it was an improvement then but I am not going to testify in court about it.
Lloyd Walker himself instructed me to remove the on/off switch from my Walker Precision Motor Controller, for an improvement in sonics. I confess I hear no difference, but mine is "on" all the time.
