Unless the specs say different I presume they used 5cm/s @ 1kHz, if they show 3.54 then I multiply by 1.4, so yeah it could well be a much higher 0.56mV for that Hana.
Reading that Hoffman link, which centres on m.m. outputs (same diff. though, I guess), the conversion figures (v2 ? What is that?) are different to to ones I was given many moons ago, which is to multiply the 3.54 figure by 1.6 to get the equivalent 5 cms/sec output. I've never needed to do the opposite calc. for obv. reasons.
One of the posts says that Benz uses the lower 3.54 figure (but he did say 'I think') but they don't; after all, why would a European manufacturer use the American standard? Of course, I'm only interested in m.c. cart's with their comparatively tiny outputs. Lyras (I've had 2) were stated 0.5mV (5 cms/sec)
but I noticed that more modern ones have upped that to 0.55 mV. I've only come across VdH and Koetsu basic range to theoretically top that (0.8 & <0.6 resp.)
That link did emphasise that measuring methods varied and could well influence the stated outputs by +/- a fraction. My Trans. Proteus states 0.2 mV at 3.54 cms/sec, which translates, if I'm right, to 0.292 but from the off and 800 hours later, its output seems a lot healthier than that. However, my K. Vermillion also has the same output but required more volume when last used 6 years ago.
Oddly, as I hate complexity and am totally non technical, I've long been fascinated by the cart./tonearm/phono stage chain. There are just so many variations in tonal and s.q. outcome, all depending on very different parameters of each link in the chain. Maybe because it's an entirely different ball-game to sticking on a CD and pressing 'play'!???? I never ventured into other digital forms (lack of interest and accelerating age, I 'spose). Playing with magnetic tape was a very creative thing and thoroughly absorbing in days or yore, come to think of it; great fun with Revoxes, Tandbergs and the top cassette recorders coming in at that stage.
