Clearaudio Stroboskop-Testplatte

The speed wobble on my deck is gone after one pass with this record, and the break-in groove really does add that extra drag for a true reading. Took me about ten minutes to dial everything in, and now the platter sounds rock-solid steady.

The break-in groove makes a noticeable difference—my turntable sounded slightly off before, but now the speed is dead accurate. The stroboscope pattern is clear and easy to read, even in dim light. This simple record saved me from guessing with a phone app.

I was skeptical about needing a dedicated test record until I saw how much the stylus drag from that break-in groove actually shifts the speed reading. Put it on, watched the strobe marks hold perfectly steady, and adjusted my platter in under five minutes. My records have never sounded this stable.
