Esoteric Grandioso S1X Stereo Power Amplifier

With the ﬂagship Grandioso amplifier models, Esoteric is breaking new horizons by pushing the limits of ﬁdelity in preamp-to-ampliﬁer signal transmission. Esoteric’s unique current transmission system “ES-Link Analog” is the ideal method for preamp to ampliﬁer transmission where the signal level is extremely low. Compared to the conventional voltage transmission, it transmits approximately 100 times more current, making it less susceptible to noise and sending the full energy of the music to the ampliﬁer.

Also, it is not affected by the impedance of the interconnects running between the preamp and ampliﬁer, so it maintains a perfect integrity between the output signal of the preamp and the input signal to the ampliﬁer.

Over-Sized Bare-Mount Power Transformers

The S1X employs the largest toroidal transformers that the S1X chassis can accommodate. The transformers performance, with a much larger size than the size required for actual use, allows for extremely high follow-through to dynamic changes in current supply, resulting in a dynamic and open sound. Also, suppressing transformer vibration results in limiting current ﬂow. For this reason, the S1X dares to employ a bare mounting with the transformer’s metal cover removed.

Power Transformer Dedicated to the Pre-Drive Stages

The S1X’s high resolution sound is also a major feature, allowing the delicate tones of each instrument to be heard clearly, even at the climax of a full orchestra performance. A power supply section dedicated to the pre-drive stage (voltage ampliﬁcation stage), which handles low-level signals from the preampliﬁer, eliminates the inﬂuence of the main drive stage, which has large current ﬂuctuations, and improves resolution.

In addition to the two power transformers for the main drive and pre-drive stages, an R-core power transformer for control is installed in a three-transformer configuration to create a pure power supply with thoroughly low noise.
