CAD Audio E100SX Large Diaphragm Supercardioid Condenser Microphone

Our review of the CAD Audio E100SX finds a microphone aimed at project studios and live performers who want a warm, vintage vocal and instrument character without sacrificing modern control. The biggest reason to buy is its large gold-sputtered diaphragm, which produces a true-to-life vintage tone that sits well in mixes and helps vocals cut through while maintaining warmth. Built-in tools such as a 100 Hz hi-pass filter and a switchable 10 dB pad give the E100SX practical flexibility for louder sources, and the included low-profile studio shock mount helps keep recordings clean.

Key Features

• Large gold-sputtered diaphragm: Delivers a warm, vintage character that flatters vocals and acoustic instruments with a natural midrange presence.
• Supercardioid polar pattern: Provides strong off-axis rejection to reduce bleed and improve isolation on stage or in dense mix environments.
• 100 Hz hi-pass filter: Lets users reduce rumble and proximity boom quickly, making it easier to capture clear low end.
• Switchable 10 dB pad: Allows the mic to handle high-SPL sources such as loud guitar cabs and drums without distortion.
• Low-profile studio shock mount: Isolates stand bumps and floor vibrations for cleaner takes without needing an extra accessory.
• Balanced XLR output: Integrates cleanly with pro audio consoles and preamps for reliable studio and stage use.

Who It's For

The E100SX is best for home studio owners, gigging vocalists, and session musicians who want a microphone with a classic, tube-like warmth but still need practical features like a pad, hi-pass filter, and robust mounting. Its supercardioid capsule makes it a good choice for live situations where bleed and feedback control matter.

Those who need ultra-low self-noise for very quiet studio work or buyers who expect flawless long-term durability should consider alternatives or test build quality first, as customer feedback on noise and longevity is mixed.

Pros & Cons

Cons

• Build quality reports are mixed, with some users experiencing early failures, so durability may vary.
