    Assuming that the flexibility of the headshell allows for more accurate tracking/tracing, why hasn't this become a standard for pivoted arms, more or less obviating the need for different lengths of arm? Bit of scepticism here from an admittedly reactionary standpoint.
    It seems there are always trade offs and compromises. Every design that makes one thing better usually cost you somewhere else. Playing Records is a very imperfect science.

    It seems that some loss is allowed in the coupling/joint in the headshell so that not all the cartridge energy is directed into the tonearm ... there are a few other solutions around that work on that principle.

    For me it makes SPU playback a bit 'cleaner' and more focused/detailed all round (not just around the end grooves), without losing that wonderful SPU body, the only reason I don't have it in at the moment is that it sits the stylus body a little low relative to the headshell connector than it does on a normal SPU, so you end up with a more tail-up angle on the tonearm, which can be dialled out if you only have one cartridge, but I have quite a few that go on this arm and I try to get them all at the same height to minimise the re-setup required when changing headshells. I have a 4mm ebony spacer on the way from Speedy Steve to mitigate this and when it arrives I'll put it back in the system again.

    The only down side from my point of view is that it feels quite fragile compared to a normal SPU headshell and needs careful handling.

    I don't see why the compliance should change? Compliance is all about mass and motion in the groove. All my my cartridges are low compliance and all my tonearms are pretty heavy.

    On the protractor question, at rest the springs centre it and it behaves like a normal headshell, in any case the SPU version has identical 52mm headshell connector to stylus tip dimensions as standard SPU, so goes straight on any arm that's already correct for SPU geometry.

    my thoughts too.
    Thinking about the Thales arm with two arm wands and pivoting headshell, all well and good but expensive to engineer and avoid the downsides. Linear tracking is fine but not necessary with modern stylii.

    I was thinking the same thing about linear tracking, it corrects the alignment problem, but creates a whole new set of other problems.

    How about this? https://welltemperedlab.files.wordpr...5/dsc04240.jpg 16” anyone? I do like Well Tempered tables. The Royal is a wonderful deck, but price is just a bit north of what I could or would ever put into a deck.
