Wes Audio ngTubeComp

Wes have brought a modern touch to bear on the most vintage of analogue compressor types — and it’s about far more than their celebrated system for plug‑in remote control.

The last time I reviewed a Wes product (the Pandora multiband compressor, in SOS February 2026: https://sosm.ag/wes-audio-pandora) I concluded that “when it comes to plug‑in remote‑controlled analogue hardware, Wes Audio are currently the ones to beat.” The couple of months I’ve spent putting their ngTubeComp through its paces has done nothing to sway me from that view: this is a truly impressive dual‑channel variable‑mu compressor, whose virtues are by no means limited to the sophisticated digital control. As with all Wes products, this one’s development clearly started with a focus on the sound and performance of the analogue circuitry that lies at its heart. In short, the ngTubeComp sounds every bit as smooth, polished and enticing as you’d hope any compressor costing the best part of £4k$5k would, and the digital control is the icing on the cake. Or rather, the custard on the pudding (I can take or leave cake, but I hate icing!).

The Way Of Wes

Most SOS readers will be aware of Wes Audio’s general approach: they’ve developed an impressive and extensive range of digitally controlled analogue hardware that can be used like ‘regular’ outboard, courtesy of a well thought‑out physical control set, but can also be operated remotely using a DAW plug‑in — the control is bidirectional, with the hardware’s controls updating the plug‑in’s and vice versa. All units can connect to a computer over USB but some, including this one, can be hooked up over Ethernet to a router, allowing you to place the unit further away from the computer. Parameters can be automated and recalled instantly with your DAW session, and while the earliest plug‑ins were laid out to resemble the hardware as closely as possible, more recently Wes have looked more to software’s strengths, with dedicated controls for the hardware’s hidden/secondary functions, and features like inverse input‑ and output‑level linking, node‑style EQ displays, and clear metering. More on that side of this particular product in the separate box.

The range includes 19‑inch rackmount devices and 500‑series modules, and all the hardware includes useful features not normally found on analogue gear. Switchable A/B/C settings and banks of user presets, for instance, facilitate extensive comparison/recall even without using the plug‑in. Dual‑channel devices can also be switched instantly between stereo/M‑S and dual‑mono configurations. But in some of the larger rackmount devices like the ngTubeComp and the ngTubeEQ I reviewed in SOS December 2024 (https://sosm.ag/ngTubeEQ), Wes take things still further, with touch‑sensitive push‑turn encoders providing access to secondary functions, and precise settings displayed on a small, yet crisp and clear context‑sensitive colour LCD screen.

Connectivity & Components

A 3U 19‑inch rackmount device, the ngTubeComp’s case extends 25cm (a shade under 10 inches) behind the rack ears. Power is delivered to the internal supply through a transformer whose inputs present to the outside world on a rear‑panel IEC14 inlet, which is accompanied by a mains AC voltage selector and fuse compartment (a spare fuse is included). Also on the rear are four XLR sockets, arranged as separate I/O pairs for each channel, plus the aforementioned USB‑B and RJ45 Ethernet sockets.

The ngTubeComp can connect to your computer for plug‑in control via a USB or Ethernet connection — the latter can be used with a router to provide a wireless connection.

Lifting the lid requires the removal of six screws, and when you do that your attention is inevitably drawn to the chunky pair of panel‑mounted Carnhill output transformers, and the six valves on the main audio circuit board (a pair of Svetlana 6N1P dual triodes and others by JJ Tesla). The valves warm the air a fair bit, of course. Nothing excessive for a valve device, and the top and both side panels are ventilated, but I’d still suggest leaving a little space between this unit and any above it in the rack. Elsewhere, a combination of traditional through‑hole and surface‑mount components is used. Separate vertically mounted boards host each channel’s controls and the global controls, and horizontal ones cater for power and data connectivity. The layout and construction appear immaculate, inside and out.

A peep inside reveals the warm glow of six Svetlana and JJ Tesla valves used for compression and, along with the Carnhill transformers, a switchable valve output stage.
