V Rail Technology
In our V Rail Technology the audio signals are processed with an unequalled +/-V DC, which corresponds to
twice that of discrete operational amplifiers and four-times that of semiconductor operational amplifiers.
The V Rail Technology reaches outstanding technical and sonic performances. Technically especially in terms
of dynamic range and headroom and sonically especially in reproducing the finest details and delivering a totally
relaxed sounding audio experience. Music sounds absolutely natural.

Comparisons
These diagrams show how our V Rail Technology compares to other circuits.
The direct relation between operating level and maximum level is fundamental for the classification: the higher
the operating level, the higher the maximum level a circuit can handle. And since virtually all essential acoustic
and musical parameters depend on this relation, a higher operating voltage also has a positive impact on the
dynamic range, distortion limit and signal-to-noise ratio.

Do bear in mind that dB scales do not represent linear but rather exponential increases. A dB increase corresponds
to doubling the acoustic power, +dB correspond to twice the sound pressure level, and +dB correspond to twice
the perceived loudness.
When it comes to volume, the V Rail Technology exhibits a performance, in regard to maximum level and dynamic
range, that is twice that of common components and circuits given that its values are approximately dB higher.
THD measurements show a difference of more than dB compared to the OPA at V — in terms of sound
pressure level, that corresponds to an improvement of more than %. The operating level most commonly used for
audio equipment is +/-  volts.
