Specifications

Here are the basic specifications – listening will of
course reveal the true quality of the Etude 5.

Price:

£13000 / pair (introductory price for first four production pairs)

Etude 5 frequency response plots; Top, chirp frequency response at 0.8 m; bottom, in-room frequency response of stereo pair; at 2.4 m in a 55 m³ room (x), at 3.2 m in a 137 m³ room (+), the average of the two room responses (●). Audiomatica Clio Pocket hardware and software was used to generate the data which was imported to MS Excel for plotting.

Etude 5 Impedance and Phase plots:

Impedance (top), phase (bottom). The Etude 5 is not a particularly reactive load, though lowish
impedance in the bass may not favour certain valve (tube) amplifiers.
