dcaudio, i upgraded my original (version l?) to mkv when i bought it, so i can't compare before-after. all i know is the parts seem to make sense to my mechanics-oriented perspective. i like the gnu bearing, i like the chassis counterweight, i like the mat, & i like the spring-cups - i got all the old pasrts, so i could compare...
i dint do the motor/power-supply mod tho - i did the origin-live dc motor/power-supply mod. this, i *did* wait a while to do, & there was a worthwhile improvement, imho - also much more cost-effective than the oracle motor upgrade... the gnu motor controls *do* look way-cool, tho! :>)
regards, doug
