Modular synthesizers have been around for quite some time now (developed in the 1950s). In fact, modular synths came well before the modern synthesizers we know today. In 1964, Robert Moog brought the Moog Synthesizer to the market: the world's first commercially available [modular] synthesizer.
Since then, many other companies have developed their own modules to fit within the Moog Unit (MU) format (also known as 5U). Though Eurorack has become the dominant format, the Moog modular format is still quite popular in the modular market. In this article, we'll have a look at the world's best 5U/MU module brands/manufacturers.
The top 11 best 5U/MU synth module brands in the world are:
- STG Soundlabs
- Club Of The Knobs
- Moon Modular
- Noise Engineering
- Grove Audio
Of course, any “best of” list is subjective by nature. I've done my best to make this as objective as possible. I've included not only my own bias but also the opinions of others (in real life, in online forums, and by which brands professionals use). I've also taken into account the number of models and the objective nature of the models in each brand.
We'll get into each of these brands in greater detail to explain why they made this list. I'll also include several module examples for each brand, along with a link to their official website and a bit of the company history.

This setup allows for boutique-like uniqueness in design and larger batches, ensuring those who want an Oakley module can get one without having to wait around for too long.
Oakley Sound Systems was founded in 1996 by Tony Allgood, and Krisp1 was founded by Paul Darlow. Both companies operate out of Northern England.
MOS-LAB is a French company that focuses entirely on reproducing the legendary Moog modules of the past. Since Moog no longer sells individual modules and the patents of these modules have expired, companies like MOS-LAB have been able to reintroduce the modules to the modern market.
The names of the MOS-LAB versions are the same as the originals, and the modules are based on the exact designs of the Moog versions. It goes without saying, then, that MOS-LAB MU modules are excellent, even though the company does not deal with their own designs.
MOS-LAB was founded by Sebastien Moumon, and the company is run out of France.

This list wouldn't be complete with Moog Music. After all, the company developed the modular format.
However, I've decided to put Moog last on the list because the company no longer sells individual modules. In fact, Moog stopped producing modules in the 1980s. That being said, the patents over the rights to Moog's modular circuits expired in the 1990s, and, since then, numerous companies (including Behringer, Synth-Werk, MOS-LAB, Club Of The Knobs and others) have recreated these legendary modules.
Moog now offers the Model 10 (link to check the price at Vintage King). It's a faithful recreation of the first compact modular synthesizer created by Dr. Robert Moog in 1971 and features several of Moog's superb modules. The modules in the Model 10 are:
- 901 Voltage Controlled Oscillator
- 901A Oscillator driver
- 901B Oscillators (2x)
- 902 Voltage Controlled Amplifier
- 903A Random Signal Generator
- 904A Voltage Controlled Low Pass Filter
- 907 Fixed Filter Bank
- 911 Envelope Generators (2x)
- CP11 Console Panel
So whether you get clones of these modules, originals on the vintage market or buy a modular synth directly from Moog, you'll have yourself some of the finest MU modules the world has ever known.
