Thermionic Culture Phoenix SB Stereo Valve Compressor Review
Built with an all-valve signal path and wired entirely by hand, the Thermionic Culture Phoenix SB Stereo Valve Compressor is a modern take on a classic design. It offers smooth, soft-knee compression that can be gentle for mastering or pushed hard for saturated, harmonically rich textures. You can easily dial in your sound with fully variable attack, release, and threshold controls. It also features a stereo link option, side chain filters to preserve your bass, and a unique standby mode that not only protects the valves but can also create analog-style distortion. It's a versatile tool that sounds as good as it looks—and it sounds incredible.
