Hello there,
The AT1009 is a descendant of the AT1005 Mk2, with quite a few enhancements along the way - VTA-on-the-fly, reduced effective mass (18gms rather than 22gms when used with its own headshell), and (a positive if you like it) the pneumatic lift arrangement.
I have always found the AT arms to have superb bearings. Many people think of the AT1005Mk2/1007/1009 as old-fashioned, but if you are using a medium to low compliance cartridge they work extremely well.
Assuming that you are building a plinth for your SP-25 project, you have the ideal opportunity to incorporate the pneumatic lift, and I think you would be well satisfied with the arm/table combination, given an appropriate cartridge.
I use an AT1009 on my Lenco GL75 project, and an AT-1010 on my SP-15, so you can tell that I like them!
Hope this helps.
regards
Angus
