Sonopress Injection Molded Vinyl - better of worse?

IMHO pressed vinyl sounds better, fresher and injection molded one sound congested.

I slightly prefer the first take. The second one sounds a bit flatter, or homogenized. The highs are annoying on both. I find the music tough to use for such a test. It is all artificial sounding. Mtemur, do you know which is which?

I am also curious why the record weight and arm in the video are wobbling so much. Neither LP is very flat.

First one is regular vinyl second is injection molded.

In addition to the warp comes with almost all new vinyl I guess he (M. Fremer) doesn’t use a washer over the graphite mat but uses a heavy stabilizer which makes the warping even worse because there is an indentation on the mat for label.

Good to know about the two formulations and their sonics. Thank you.

I wonder if the record weight is not machined very accurately. I understand what you’re saying about no washer. I had one with the SME and it worked fine by clamping the outer edge of the record to the platter. My new turntable platter surface is very slightly concave with a pretty heavy record, weight and leather mat. My most warped records are perfectly flat with this system, and there’s basically no up-and-down movement of the arm.

I always look at videos of turntables to see if I can observe the platter or record weight rotating. If they don’t have any marks and are machine accurately, it’s often very difficult to tell if the platter is spinning or not.
