Kind sir, curious, for the sake of comparison was the Garrard 301 Loricraft model you previously owned also using the "hollow box frame" style stock plinth with the rest stock? Any modifications? Curious as to which era ie. version the used Mk.3 Dobbins you purchased, there were a couple slight variations if memory serves. In any event, I believe you will really enjoy your Sp10Mk.3 based drive front end. When they are well implemented, these direct drives are musical powerhouses. I adore mine!
LewmAgree on your post above with regards to musical neutrality ~ transparency, as these traits the Mk.3 excels in. On a friendly side note, Kodo the Beat actually does not use a Mk.3 motor or Technics platter.
