New tonearm: wish to upgrade from DV 505

the cartridge is a Kiseki Agaat (retipped). The complete setup plays nicely. The question is whether a change of the arm could reveal even more information out of the vinyl.

Hi Paul, coming back to your question concerning drive stability, I had a similar experience like the one Frank had told you. It happened (only) once when touching the grounding (earthing) of the tonearm cable that the speed jumped from 33rpm to 45rpm. An immediate reset using the speed control panel was possible. So far (knock on wood), I observed no other adverse reactions/side effects. The PX 100 really is the gem you mentioned.

many thanks to all of you for the valuable input.
@ Raul: your knowledgeable suggestions are especially useful, I will go for the points you mentioned.
@ Lewn: comparing the PX 100 M to the Clearaudio Maximum Solution with magnetic bearing, the PX seems to have an inbuild stability in sound production which is fantastic at least in my ears. The Max Sol needs the outer limit stabilizer ring to come pretty close.

Thanks, Paul. I already contacted Frank Schröder for an appointment to compare the alternatives.
By the way, are you the lucky one who owns 2 (t w o) of the PX 100 M DDs? Which tonearms and cartridges do you use?
