To all members i thank you all for the appreciation . those who are technical minded can read about the design below.
Maya Power Amplifier comprises four discrete stages; Input Stage, including a feedback node; Voltage Amp stage; Driver Stage, and the Output Stage, which uses a single pair of very large 480 watt mosfets in complementary push pull. These devices feature very low 70milliohm Rdson and a very high transconductance around 30 Siemens, much higher than bipolars.
The signal undergoes no phase transitions from start to finish of the Maya. 99% of analog audio amplifiers utilise gain devices in common emitter/source, where input to base/gate creates current and voltage amplification at the collector/drain output. This topology brings a 180 degree phase transition, so two such devices in series bring 360 degree phase change from input to output. These single transitions incur phase shifts, driven by parasitic parameters in the active devices; this approach adds noise, restricts bandwidth, and so is a clear impediment for high fidelity audio amplifiers reproducing music at the highest audiophile levels.
The Maya topology completely eliminates phase transitions and brings almost negligible phase shift input to output. This feature alone delivers intrinsic stability and signal linearity within a global feedback amplifier. In fact, the Maya is such a stable amplifier that no lag compensation is used. The Maya needs only 29dB of global feedback, a marked reduction on the usual 60+ dB of most SS AB amplifiers. The amp speed is very fast, and 1dB points are at 15Hz and 245KHz, excluding the low pass input network. The phase shift is just over 2 degrees at 20KHz which confers a wonderful soundfield, supernatural quiet, and stunning sound clarity.
