    Isn't the "gentle dishing" going to change the attitude of the stylus to the groove. I know we are only talking about a couple of millimetres fall from outside edge to run-off, but given how much effort we put into getting our azimuth correct, it seems perverse to then deliberately change it by making your records dish-shaped.

    Don't get me wrong- I'm not trying to say that "it's everything that the oyaide is, plus more". All it is is a $20 chunk of steel. There are probably benefits, but possibly negatives too. I'm keen to hear both.

    As for starting torque- it seems to take about half a rotation to get up to speed. I think a standard platter takes a quarter rotation

    I just laid a straight edge on my VPI Acrylic platter, and it's perfectly flat. So I know it works great, nothing wrong with perfectly flat.

    Dished may have an advantage of flattening records, and if you do have a dished platter, or mat, yes it will change the azimuth of the needle, but when you set the cartridge up you need to compensate for that, square to the record, wherever it is. Running downhill towards the center of the record could also have an effect on anti-skating? Although one millimeter in 140mm or more is a very gentle slope. Anyway, certainly nothing wrong with perfectly flat.

    Seeing that the stainless disc is some 5mm thick, I wouldn't be too concerned with ringing either. Hopefully it's resonate frequency will be well above the problem areas associated with vinyl playback. Yes it may fall within the audio range, but at higher frequencies it may only present itself as a brighter region, and may even compliment certain cartridges?

    Of course, the proof is in the pudding! What do you hear? What differences are you hearing with, and without the new Stainless mat? That's what is and is only important! Any change in bass control? Overall character? Pace and timing? Remember that adding 5mm to the height of the platter will alter your VTA, be sure to adjust for that.

    Hi The Oyaide MJ12 is NOT SS it is Tuned Aluminium , so it does not ring like a bell , and the weight is a lot less than SS i hope that helps

    Just seems all wrong to me. Having the cartridge tilted in order to achieve square-on azimuth will result in the needle "leaning" on the inner groove wall and I would expect it to create exactly the kind of unequal groove-wall pressure that we obsess about. Expect the channel balance to be out. And anyway, surely you wouldn't choose to treat your records like that ...?

    That's why I said it may affect anti-skating, you may have to crank it up to keep it from leaning on the inside groove. I agree it's not ideal. Maybe it would be better to tilt the record player up so the track of the needle is level? Still kind of wonky. Honestly, I think we are seeing an exaggerated bevel, perhaps it's not that steep? In reality it's not out of level enough to compensate for it? I can see a lot of reasons to keep it level, warped records all be damned.

    The dirty truth comes out- I'm a pretty pathetic audiophile. I rarely critically listen, or even sit and listen. The goal here was just to see if I could improve w&f, and create something cool for cheap. I haven't had a single sit-and-listen session

    I'm concerned about the stress on the bearing so I plan to switch to aluminium and copy Oyaide's holes. My measurements didn't show any improved in w&f anyway, so the priority is back to "cheap but cool"

    Then you can save you sit and listen sessions to compare the two new platter mats! SS vs Aluminum! It really doesn't have to be difficult, just pick a few albums you know well, and hear them both ways. An hour could be most telling as to which is best?

    Not a bad idea. Aluminium weighs 3 times less, which brings it to a far more reasonable 850g. Add some holes and I'll have a more lightweight, but very funky platter. It's a shame the steel hasn't worked out for me, but $20 was worth the test- and the discussion here
