Michael Lavorgna of Twittering Machines noticed that his Credo speakers had a bit of room to sway if gently pushed, and Michael Kraske, who designs them, wants it that way. He doesn't want a rigid connection to the floor, so instead of spikes his speakers stand on a machined aluminum base with soft, donut-shaped pads underneath. Steve Guttenberg explains that this keeps the speaker from putting energy into the floor. Inside the cabinet, Kraske's focus is timing. The crossover, the circuit that splits the music between the drivers, uses slopes that start gentle and grow steeper, and Kraske lines the drivers up in time through the crossover instead of tilting the front baffle back. Guttenberg found the EV 900 Ref.'s imaging "extremely coherent," and Lavorgna heard "crystalline clarity that never gets edgy" from the EV 1202 Ref. Credo suits listeners who care about imaging and want to hear the character of their amplifier come through.

The EV 350 Ref. stand-mount is the way in. Marc Phillips of Part-Time Audiophile drove it with a low-power class A amp and heard no strain, and in his room the bass behaved "as if they had a little room correction gadget tucked away in a spare pocket." For the step up, Credo designs the EV 900 Ref. for medium rooms and the taller EV 1202 Ref. for medium to large ones. Guttenberg set his EV 900s about 4 feet from the wall behind them and recommends an amplifier that likes low impedances. The EV 900's terminals offer a brighter tweeter setting, which Kraske suggests for over-damped rooms or soft-sounding electronics, and the EV Reference One comes with resistors that set the tweeter and midrange levels. Dave McNair backed the tweeter off "by just a hair" to suit his room. Lavorgna drove the 1202 with amplifiers from 25 to 150 watts and enjoyed every pairing, with the Mola Mola Kula for tightly controlled bass and the PrimaLuna EVO 300 for richness.

Michael Kraske's parents founded Credo with a hifi shop in Basel, which became known for repairing and modifying JBL speakers. Guttenberg reports that Kraske built his first speaker from a kit at 7 and designed a complete one at 14. He played cello in his school orchestra and spent years mixing and mastering in recording studios, and he still records and masters for Naïve Records. Credo makes its own cabinets, crossover boards and speaker terminals in Switzerland, and Guttenberg notes that the EV 900's drivers are built by ScanSpeak to Credo's specifications. The EV series grew out of the SPC series, which Credo built for almost fifteen years. At the top is the Cinema LTM, a passive line array named for La Tour Maubourg, a project in Paris. In Lavorgna's barn it set the glass of a pinball machine vibrating. At AXPONA 2023 Phillips heard a pair of EV 1202s playing beside the LTMs and was sure the big arrays were making the sound.
