A rack of outboard gear at The Bunker in Los Angeles

That end-of-year energy is in the air again, and it’s the perfect time to round up the outboard gear that defined 2025, from preamps and EQs to compressors and effects processors. This year brought a wave of exciting new releases alongside the classic designs that continue to anchor modern studios. From 500 Series essentials to flagship rack units, here’s a look at the gear that topped our charts in 2025! 

Neve 1073SPX Microphone Preamp/EQ

Taking the #1 spot for the second year in a row, the Neve 1073SPX continues to prove why it’s one of the most trusted front-end tools in the industry. Handcrafted to the original 1970s specifications, it delivers that unmistakable Class A sound: big, punchy, and rich with musical harmonics. With its iconic three-band EQ and silky high-pass filter, it’s the secret weapon for adding instant vintage vibe to any source, from vocals and guitars to entire mix buses.

If you're looking for something with a few more inputs, be sure to check out the dual-channel 1073DPX or the eight-channel 1073OPX.

Making a huge jump from last year all the way up to the #2 spot, the Teaching Machines Wellspring has clearly struck a chord with engineers and producers craving authentic analog character.

This boutique analog stereo spring reverb features an onboard stereo delay, modulation, and a "Magic" feedback knob that can create everything from subtle ambiance to self-oscillating soundscapes. With its four real springs and extensive hands-on control, it delivers the lush, textured decay of a vintage unit with the flexibility modern workflows demand.

Also up several spots from last year, the Trident 80B EQ continues to win over engineers with its unmistakable musicality straight from the legendary Series 80 console. This four-band EQ features frequency-switchable high and low shelves, two sweepable mid bands, and a resonant Q that just feels right when sculpting sounds. It’s the perfect tool for adding that classic, punchy rock ‘n’ roll vibe to any source.

Universal Audio 1176 LN Classic Limiting Amplifier

The Universal Audio 1176LN is a hand-built reissue of the legendary limiting amplifier that has shaped the sound of hit records for over five decades. This iconic FET-style compressor delivers colorful, punchy compression with ultra-fast attack and release times, making it perfect for vocals, drums, and more. With selectable ratios and the famous “All Buttons In” mode, the 1176LN offers everything from subtle leveling to full-on, aggressive character.

Solid State Logic Revival 4000 Channel Strip

Solid State Logic Revival 4000 Channel Strip

Newly released this year and already making waves, the Solid State Logic Revival 4000 is the first new entry to crack our list of best-selling outboard gear. This all-analog channel strip faithfully recreates the brand’s most celebrated circuits, including the preamp, dynamics section, and 4-band EQ from the original E-Series channel strips, and a one-knob de-esser from the rare 4000 B console. 

BAE 1073MPL 500 Series Mic Preamp

BAE 1073MPL 500 Series Mic Preamp

As one of the most popular preamps ever made, it's no surprise to see more than one version of the 1073 on our list. The BAE 1073MPL brings the legendary Class A sound of the iconic 1073 to the compact 500 Series format, delivering harmonically rich low end, slightly resonant highs, and tightly focused mids that have made the 1073 a studio staple for decades. 

Built with Carnhill St Ives transformers and the same hand-wired attention to detail as the original, the 1073MPL offers authentic vintage tone with modern features like a line-level input and high-impedance DI for added versatility.

Behringer 73 500 Series Microphone Preamp

Behringer 73 500 Series Microphone Preamp

Newly released this year, the Behringer 73 makes the iconic 1073 sound more accessible than ever, earning its spot as the most affordable 1073-style preamp on our list. This 500-series module features a Class A, all-discrete signal path and custom Midas transformers to deliver that classic, thick and mid-forward tone. 

With its simple controls and high-impedance instrument input, it’s a perfect entry point for anyone looking to add a touch of vintage British character to their rack without a vintage price tag.

SSL SiX CH 500 Series Channel Strip

SSL SiX CH 500 Series Channel Strip

On our list of best-selling outboard gear for the 5th year in a row (and every year since it was released in 2021) is the SSL SiX CH 500 Series channel strip. Based on the beloved SiX desktop mixer, this compact module packs SSL's SuperAnalogue mic preamp, a flexible two-band E Series-style EQ, and an easy-to-use single-knob compressor into a compact 500 Series module.

Rupert Neve Designs Shelford Channel

Rupert Neve Designs Shelford Channel

The Shelford Channel brings together the best of Rupert Neve’s legendary console design into one signal path. Combining a genuine Rupert Neve-designed transformer-gain mic preamp with a vintage-style Inductor EQ, a musical diode-bridge compressor inspired by the iconic 2254, an innovative dual-tap output stage, and RND’s signature Silk circuit, the Shelford Channel distills decades of innovation into a single channel strip.

Cranborne Audio Camden 500 Series Microphone Preamp

Cranborne Audio Camden 500 Series Microphone Preamp

The Cranborne Audio Camden 500 has earned its spot on our list year after year thanks to an astoundingly transparent and detailed sound that stands toe-to-toe with far pricier competitors. 

Its fully discrete, transformerless design delivers vanishingly low distortion and a ruler-flat response that stays clean no matter how hard you push it. But when you want character, the Mojo circuit gives you two distinct flavors of analog saturation: Thump for low-end heft and harmonic weight, and Cream for smooth, vintage-style warmth.
