Speed Box for turntable

Bernardwong, I can't speak to the Junior, but I can as to both the VPI 19 MkIII and the VPI Scoutmaster. With either the Walker Audio motor controller or the VPI SDS motor controller, these turntables benefit as follows: the background gets blacker (the silence between the notes), imaging is more stable, and instruments take on a greater solidity and greater apparent dimensionality. The improvements are material and, depending on the resolution ability of the remainder of your system, these improvements either are immediately noticeable or are noticeable after you've lived with the motor controller in place for a week or so and then remove it. However, there may be greater improvements to be gained by upgrading your turntable in other ways before adding a motor controller.

Dlwask, your suggestion not to worry too much about an aftermarket power cord from the wall to the motor controller makes sense and is very sane advice. But in the spirit of full disclosure, I will offer that the choice of power cord *can* make a sonic difference in some systems. In my system with the higher level Walker Audio motor controller and the Walker Proscenium turntable, this is the case. It's nuts, but we can hear the difference. In this crazy hobby of ours, this is just another example of the truism: "everything makes a difference." Cheers.

Totally agree with you about being left scratching my head in disbelief on many of these issues, Dlwask. That is one of the never-ending mysteries for me of this hobby. :-)

Yes, the Walker Proscenium tt is a treat. If you're ever in the Philadelphia area I'd enjoy having you over here to share some music. Same to other Audiogoners.
