Is analogue better?

Vinyl is a cost-effective way to get into proper audio. Some experts argue it it gives a better experience than digital, with a lack of compression and a naturalness that’s hard to replicate.

Digital relies on a computerised interpretation of sound-waves. Turntables and records, however, maintain analogue integrity by translating these sound-waves into physical grooves and vibrations rather than 0s and 1s.

I liken turntables to coffee. They can be terrible or wonderful.

Rightly done, they'll produce a brilliant sound and last you a long time. But the bad ones sound gross and can damage your records.

It's all about materials and construction. A turntable is a mechanical instrument that needs to measure record grooves in a delicate way.

What to *avoid* in a turntable

This product page will run through what makes the Primary E such an ace deck for the money. But what shouldn't be inside a turntable is just as important as what is. Here's a summary of the things to avoid, and we've got more detail here.

Inbuilt speakers. This is baaaaad. They're small and tinny, so you'll be strangling whatever signal does come out of the record. But also the vibrations being inside the chassis create a feedback loop which goes back into your records.

A tonearm that's too short or made out of the wrong materials - this will interfere with the accuracy of what's embedded in the record. Small platters are bad too - they'll eventually warp your records due to the edge overhang.

Stylus and cartridge that put the wrong pressure on your records or are made out of bad materials. These will distort your sound and potentially damage your vinyl.

Cheaper motors that don't spin precisely in time. You'll hear higher or lower pitch in your music.
