540A v2 - High performance integrated amplifier
For these
version 2 models we have been able to further improve the audio quality and
make them more powerful through many detailed changes and enhancements
developed as a result of our on-going research programme. We have also added
some new features, including support for Multi-Room use. All this proprietary
engineering is housed within our low resonance, acoustically damped chassis. An
Azur Navigator remote control is also provided, giving full remote control of
four amplifier in an attractive and easy to use handset.
The 540A
V2.0 features a new preamp stage with buffered inputs for lower crosstalk and
improved stereo imaging, whilst the headphone output is now provided be a
separate Class A headphone driver circuit. The amplifier stage has been revised
with new low-noise input transistors, special driver stage PSU regulation, a
new voltage amplifier topology and separate current sources for the voltage
amplifier and predriver stages. These enhancements to the original circuits all
work to elevate the sound quality to a new level. A new heatsink and
transformer are employed and the power output is now 60 watts per channel (from
50 wpc on the V1 model).
With output
at 60 watts per channel, the 540A Version 2 is a clear leader in budget
amplifier circles offering a huge number of features and a build quality to
embarrass more expensive rivals.
The 540A
features full remote control and dedicated multi-room connections.
