Basis Vector cartridge recommendations

Out of the 3 you list I would go Lyra. Otherwise maybe dyna xv1s

I had the Vector arm and now I have the Super Arm 9. I am using the ZYX Ultimate 2 and the sound is fantastic. I tried lots of cartridges with Basis and I like this the best. Ones I have tried are Koetsu, Clearaudio, Benz, Vandenhall, Myabi, etc.

Thanks Jwm, I remember the threads about your Super Arm and how impressive it is! Hopefully you pop back on this thread and can comment on the synchro wave power supply and if it is worth the money?

Yes pops the Synchro wave power supply is a must have. It gives you a much smoother platter rotation and gives a much quieter background. I have observed without the synchro the motor vibrates and can send some of this to the platter. I noticed when the synchro is connected the motor becomes dead silent with no vibrations at all.

The Synchro wave power supply does a good job of smoothing the motor out, in part, because it splits the phase to the four pole motor and delivers two separate power feeds to the motor (the motor has to be sent back to Basis), instead of using a capacitor in the motor itself to split the phase. This is the superior way to provide outboard power. Those motor controllers that don't provide two separate phases of power (i.e., the type where one simply plugs the motor into the power supply) and rely on a capacitor in the motor are particularly less desirable when the controller is also used to change speed; the capacitor can be made ideal only for the 60 hz frequency that drives the motor and a change in frequency to change speed means that capacitor cannot be properly splitting phase.

I like the Synchro with my Basis Debut, but, I would characterize the improvement as fairly subtle (Basis already delivers a very quiet background without the Synchro). To me it is worth the money, but, I would not want anyone to expect too much of a difference.

Anyone with an old belt should replace their belt. Not only is a new belt always better, Basis has improved the quality control in manufacturing belts and this really boosts performance.
