Tonearm for Technics SP-15

I have a Technics SP-15 turntable with a Grace 707 arm and a Grace F9E cartridge with a Soundsmith new stylus.  This combination sounds great but is limiting.  The 707  tonearm has a fixed headshell and it does not allow me to easily swap other MM  high compliance catridges or match compliance requirments MC cartridges.  Suggestions welcome from those more expert than I.  


You can also look for a Technics Epa 250 multipurpose, on-the-fly adjustment for this arm too saving several dollars compared to the Epa 100 .... the natural match with the SP15

chakster, others,


If looking for a used EPA-100, what are the things to be concerned about?

questions to ask? 

Elliott, the Technics EPA tonearm guru is a fellow that goes by JP and can be found at the HiFi Haven forum as well as other places. Do a search on that arm there, he does a repair to the fragile ruby bearings as used on them.

Interesting to read the ad copy on this arm in the Ebay add you linked. It makes it seem that the armtube is made of Titanium Nitride. Had to look into that as that stuff has always been vapor deposited as a very hard wear surface used on cutting tools. I never heard it used as a material and looking into it all I see is surface treatments. So the arm tube is aluminum with a surface treatment, very dubious as to it’s benefit. I have the same type of arm tume on my Technics SL-M3 LT stashed away.



@elliottbnewcombjr you have to make sure about the bearings, loose bearings must be avoided.


@billwojo epa-100 can be found in perfect condition and you don’t need a pepair "guru" if you will buy a perfect sample. Broken samples must be avoided from the start.


"The EPA-100 tonearm represents several significant advances in tonearm technology. A variable dynamic damping system which permits the user to tune the arm for compatibility with virtually any cartridge now available. An extremely stable 4-point Gimbal suspension employing ruby ball bearings which maintain static friction at 5mg or less for movement in any direction. A titanium nitride shaft which is light and also resistant to flexing and resonances. These elements all contribute to one end, keeping the stylus in optimum contact with the record grooves. Although this many seem elementary, the ability of the EPA-100 to perform this function in a high grade sound system can make a noticeable difference in the clarity and openness of the resulting sound."

Dear @arneama22  : Your Grace is very good tonearm, yes not so easy to change cartridges as tonearms with removable headshells. You can find out a Grace 1040 that's really good removable headshell design.


Btw, @billwojo you are rigth about Technics tonearms and the EPA 250 that I still own is even superior to the EPA 100.


The 250 comes with 3 different arm wands and with the same VTA unique mechanism made it with the EPA 100-MK2 that's that VTA mechanism the best ever made in any tonearms including today top models.
