    Unfortunately it isn't. Measurement of the arm's vibrational characteristics show it to be markedly inferior to the straight and well damped tube of the SA-250ST and this translates into a sound that is less well focsed and comparatively lacking in drive.

    The same is not true, of course, of the SA-750D.

    Hi Adam,

    Thanks for the info. If you've tested it, then fair enough

    I'm simply rallying against the age-old bias in Europe (particularly in the UK) against S-shaped tonearms with detachable headshells, where often such bias isn't sonically justified.

    That's interesting, thank you Adam.
    So, if I want a replaceable headshell I have to go for the 750D, no alternatives...

    Hi Giovanni,

    Ortofon also produce a re-badged Jelco SA-750D at double the price, which apparently has a better damped armtube.

    There is also the classic Acos Lustre GST 801 (shown below), if you can find one in good condition

    Hi Marco,
    I just need a not-so-expensive tonearm, with a replaceable headshell, to play with, but I don't want to get a used one. I guess the only choice is the Jelco SA 750D.

    I can't think of any others off the top of my head, but I can contend from personal experience that the 750D is a superb tonearm, and punches way above its weight, sonically. It's unquestionably a £1000 tonearm with a £450 price tag.

    I've just fitted my new Ortofon SPU Royal GM to it and, goodness me, what a superb combination that is - undoubtedly one of the finest I've heard!

    Currently spining The Beatles 'Help' album, and the music has never sounded so natural and believable through my equally vintage Tannoys!

    Marco, I know the Jelco 750D is a very good choice (since I have a DL103SA, it is the *best* choice, too), but I'll wait for a little more, to see if some 12'' arm solution for the 1200 will arise somewhere. Otherwise I'll go for this http://www.trans-fi.com/terminatortonearm.htm
    since you can swap very easily the tonearms, it is possible to change cartridges just like I want to do.

    I asked Vic and he said the Terminator is a good companion for low compliance cartdridges, too.

    What you think about that toneamr, Marco?

    I want a terminator for mine long term... Even just for a week ... I still say it's one of the coolest bits of kit I have ever seen!!

    By all accounts, Giovanni, the Terminator is a superb tonearm. I've not heard one myself, but John (Music Room Mod) has on many occasions, and Vic is a personal friend of his, so John's your man for advice on that one
