The new Esoteric S-05XE Class A Stereo Power Amplifier builds on the highly regarded S-05, retaining its beautifully pure Class A design while introducing a number of significant upgrades derived from Esoteric’s flagship Grandioso amplifiers. Delivering 30 watts per channel into 8 ohms, the S-05XE combines the transparency, texture and natural musicality associated with Class A amplification with the scale, control and dynamic authority that has become an Esoteric hallmark.
At the heart of the XE is a new, larger 1,000VA toroidal power transformer, replacing the 940VA EI-core transformer of the previous model, alongside a redesigned dual-mono power supply for improved channel separation and greater dynamic performance. A new fully symmetrical balanced input buffer further improves signal precision and noise rejection, while Grandioso grade capacitors and Esoteric’s minimal-feedback circuit philosophy remain central to the design. The result is a substantial evolution of the S-05, retaining its effortless character while bringing greater openness, precision and dynamic expression to Esoteric’s 05 Series.
