I bought an Argon TT-4 (not the MK2, but the MK1 is no longer available) two years ago and while my taste in music is somewhat limited/one-sided, I love listening to records!
Now, sometimes, I come across records that are thicker and heavier than others, for instance two of my Nancy Sinatra albums and Madonna’s Immaculate Collection, if I remember correctly (=too lazy to reach down for it now…).
Why is this? Does it signify a change in the manufacturing process over the ages, as in, thinner records are newer simply because technology evolved? Or was it a conscious choice to make some thicker? I can’t quite distinguish any difference in sound quality, since I’m using a pretty high fidelity Ortofon 2M Blue cartridge with some sic Adam A5X monitors…
Please advise! 😊


180g don’t have deeper grooves. The groove depth is set by the mastering engineer before pressing, and will be the same at any weight. A thinner standard record will have exactly the same groove as the 180g version if they are from the same master.
