    New Jelco Tonearms

    http://www.monoandstereo.com/2017/08...nearm.html?m=1

    I'm surprised no one has mentioned these yet. I think they deserve serious consideration, not only for the affordable cost levels, but for the new knife edge vertical bearing, the choice of static or 'dynamic' balance, and Baerwald geometry. The latter has the advantage over most other past and current Japanese arms, such as Ikeda and FR, which have a bizarre geometry requiring twisting the cartridge in the headshell to obtain more conventional alignment like Baerwald or Lofgren B.

    Most welcome. Another advantage benefits SPU users. Perfect Baerwald alignment is possible with these arms, whereas any reasonable alignment of SPU with Ikeda or other Japanese arms given their very strange geometry is impossible to achieve since obviously the SPU cannot be twisted. For instance, if you try to setup an Ikeda 407 with SPU, you cannot find a single null across the record. You have to play with the pivot to spindle distance to find any sort of compromise.

    This might be a decent upgrade - the 750D is already no slouch.

    The release of these arms was delayed due to some production issues. Mine is scheduled to ship next week so Iíll report back.
