    imo go with getting the cartridge parallel to the platter and dont worry about the arm,besides its not that important with the 103 as in stock form it has a conical tip.
    Thanks for the tip. My primary reason for adding a spacer is to increase the effective mass of the tonearm. People in the know claim that DL-103 likes higher mass, so I'm eager to try.

    I was hoping that the side effect of making the cartridge taller by a few millimeters would result in tonearm not being so close to the platter. Of course, that's after adjusting the VTA and ensuring that the cartridge body is parallel to the record surface.

    i dont know the effective mass of your tonearm but for what its worth my 103 worked very well on a zeta tonearm with a mass of 16g,i tried adding mass but found it sounded much better left as it was.
    have a play with blu tak to add weight to the headshell and see what you think.

    Jelco SA-750E effective mass without cartridge is 13.26g. Your tonearm definitely is a better fit for DL-103 as far as effective mass goes.

    Marco had a link to a damping spacer which is also good but I cant remember where I got that from, it could be this one

    Thank you Alan, this is gold!

    So, knowing that plain DL-103 weighs 8.5g, and that Jelco SA-750E counterweight can handle up to 12g, I have 3.5g wiggle room to play with. How can I figure out how much do these spacers weigh?

    I made this statement in my thread
    The only spare head shell I have is a an Oyiad carbon fibre type which weighs in at 10g, with the stainless bolts and the shims I get 14g.
    So stainless bolts and shims added 4g thats as much as I know unfortunately

    I found the std Jelco VTA collar is poor with its single grub screw that can put the post off centre.
    There is a reasonably priced solution to this that uses a more rigid mounting method and IIRC a micrometer to adjust VTA (not dissimilar to Audiomods.)
    When i am on a laptop i will try to find it and post a link.

    If you need to adjust the height, both of these will allow the pillar to rise vertically instead of at an angle.
