Sound Characteristics
Modern, clear, high-resolution sound: A straightforward tonal character with minimal coloration—typical of Sony’s design philosophy at the time. The high frequencies feature excellent extension, creating a very clean and refreshing impression.

Delicate expressiveness: The sound offers a fast attack and excels at capturing subtle sonic nuances. It is an excellent choice for classical chamber music and clear female vocals.

Subtle yet powerful: Utilizing an "audio current transfer" design, the amplifier remains resilient against fluctuations in speaker impedance, delivering a bass response that is more solid and substantial than its appearance might suggest.

Sound Quality: Comparison with the ESX Series and Later Models
The "delicate" ES versus the "weighty" ESX and subsequent generations: From the ESX series onward—featuring the renowned "G-chassis"—the design incorporated rigorous vibration isolation and a more extensive use of materials, emphasizing a thicker sound and a more forceful, driving bass. In contrast, the original ES is characterized by finer sonic particles and a lighter, faster sound.

- Center of gravity of the sound: From the ESX onwards, the center of gravity is low, resulting in a solid, pyramidally balanced sound; the original ES, however, has a slightly higher center of gravity, which places the emphasis on transparency in the upper-mid range.
