Less of a classified, more of a blog...

I've been looking for an interesting turntable for a while. I became aware of the work of Stefan Strohmetz some time ago but had taken some time to follow it up & make contact. The STST website is all in German. Although the company has been going since 1985 most of what he produces appears to stay in Germany. Anyhow I finally did get in touch when reading about the direct drive Motus models. Seeing some photographs & reading the sparse information available I decided that I liked the approach they were taking. Each deck is hand made and is available in pretty much any finish or combination of finishes that you want. The direct drive motor itself is made in house. The Motus can be ordered either as a solid or suspended design. I already use an SP10 mounted in around 60 Kg of slate which stands on sprung isolation so I decided to opt for the suspended version. However the approach taken by STST is very different to that applied by Technics. Whereas the SP10 uses a very powerful motor to control a moderately heavy platter the Motus designs opt for a heavier polymer platter driven minimally by a less powerful motor. The thinking behind this is that the higher powered motor also has the potential to introduce some low level noise the effect of which is to mask very low level detail & to overlay proceedings with a slightly coarse or even 'grey'quality. This can be ameliorated to some degree by judicious choice of tonearm & cartridge but it isn't an ideal situation although undoubtedly adequate for broadcast purposes.

Anyhow, the upshot of this is that I ordered one asking for Linn & SME armboards, chose a finish (Maple with CF top plate) and sat back to wait. The reason this thread is in dealer classifieds is because if I like the deck I can sell them here in the UK. Strohmetz was wary about such an arrangement at first and asked how many I might sell in a year. When I said, maybe 2 or 3 he relaxed somewhat. I think if I'd said 10, he'd have told me to look elsewhere. They aren't something he is looking to sell alot of.

2 large boxes arrived today, one containing the deck & platter, the other, presumably the lid.

So with some excitement I began to unpack it.











The brass weights to the side are counterweights that are mounted to the sub-chassis to counter the weight of the tonearm used such that the suspension acts around the inverted main bearing. I like this approach. I have a Voyd in the loft on which I have a similar, albeit less elegantly executed, arrangement.

All of the component parts I've seen so far are beautifully made, even the hinges (which look similar to those used by Linn & others) but which are properly made, again in house, from metal rather than the plastic which the spring eventually used to break.

Now I need to get my SMEV down from the loft & fit it, but I also need to get Stefan to send me the text of the owners manual so I can translate it via Bing.

I'll document the assembly as it happens but so far alles gut!

Lovely looking thing Guy, I'll be very interested in your thoughts on the performance :^

I'll have to bring it along to Andy's gathering. I want to try the SME, Alphason & FR on it first and see if it has a preference!

The plinth & top plate lift off as one piece leaving this visible underneath. Note the 3 suspension 'towers' and the threaded bars to carry weights allowing balance of the suspended chassis once a tonearm is added.





It does seem very nicely executed.

Off/33/45 switch is underneath at the front which will be easily accessible once the feet are attached.

The 'Made in China' carton is from something else (lightbulbs) :D

I'll have a closer look shortly.

EDIT. Difficult to say. Not metal although it is quite cool to the touch. Not MDF but some kind of composite I think. I've sent him an email to ask.

Each of the suspension towers has the facility for variable damping. The bearing is verrrry smooth.

Re Subchassis.

einem extrem biegesteifen, hochdämfenden Schichtkunststoff

which Bing translates as 'an extremely rigid, hochdämfenden layer plastic'. Not sure what hochdamfenden means but it is some kind of stiff, laminated plastic/polymer material.

I like the idea of an inverted bearing and counterweight in the subchassis for balance, there seems to be a correspondence between the cool contemporary looks and the simple, elegant solutions to design issues.

From a selling point of view it is the opposite of the over-engineered bling TTs (mentioning no names ;-) ). It might be a challenge to sell loads, but that seems low on the agenda. I approve (FWIW!)

I love that for its intelligent engineering.

The idea of allowing variable counterweights to offset the mass of the arm is at once simple, yet brilliant.

How many times have we all seen suspended decks where the whole thing is cocked-up by the weight of a substantial tone arm? Hardly a new problem, yet one that I don't think I've ever previously seen addressed in such a straightforward and intrinsically correct manner.

Difficult to see from the pics, but it looks as though the sub-chassis is layered.

If it sounds as good as it looks, then it's going to be rather special.

does look like one of those resin bonded composites.

Loving the initial 'striptease' pic sequence lol.

Are you loving your final choice of colours and materials now?

I've been looking forward to the arrival of this, looks very promising Guy. :^

Give how easy it is to remove the plinth & top plate I'm sure I can get an alternative set with perhaps a darker wood & maybe a brushed metal top plate to drop on & show a different finish. I do like the Maple & CF though, it looks quite understated but also contemporary.

Will put up some close-up shots of the suspension & dampers later. I've just picked up a Clearaudio arm alignment gizmo from Stu to get the spindle pivot distance spot on although the sled arrangement the SME has allows for a fair range of adjustment anyhow.

Is it wrong to be lusting after a turntable less than a week after getting a new one?! Looks lovely Guy!
