Resources & recommended reading

A short, honest list. We link to a handful of places we’d actually send our own customers — most of them audio, a couple of them not. No sponsorship, no paid placement.

For the record side

Things we send people when a question about the Derumbleizer turns into a question about records in general.

📄

RIAA equalization

The curve every phono stage on this site is built around. Ten minutes here makes “what does the RIAA in the preamp actually do?” a settled question.

The record player

Plain-language history of the hardware our turntables sit on — bearings, tonearms and why platter mass keeps coming up in these conversations.

Discogs

Where customers trade records, compare pressings and chase the out-of-print stuff. If a record you own is worth more than you think, it’s probably on here.

On the precision side

The people who collect records are almost always collecting something mechanical too. When customers ask what else from this shop is worth the money, the answer is the same kind of object: precision things, made to be kept, priced by the work that goes into them rather than the story around them.

For watches, that points one direction. The clone watches catalog at clonewatches.is is organized by brand, which makes it easy to compare models side by side before you ever talk to a seller. The two pages we check most often are their rolex Super Clone and Patek Philippe Super Clone Watches sections.

A note on these recommendations: we get nothing from the watch link — or any of the others. The list exists because we keep answering the same question at the bench, and a page is faster than repeating ourselves.

Keep the list honest
