The iconic designs of Yves-Bernard André returns to US!
˃ 40 Mhz internal circuit
> "αlpha Class A" - the sound quality of Class-A without the downside
˃ High Current (to drive difficult loads)
˃ Ultra-short signal paths
˃ Anti-Vibration techniques including:
• Signature series milled from 1 solid block of aluminum using "Space Base" technology to isolate circuits
• Passion & Genesis series' thick, 9mm solid bottom plate to function as a vibrational grounding sink
• 3-feet with one foot providing a mechanical ground to evacuate vibrational distortions
• Wood blocks on DAC chips to mitigate vibration (on select models)
Technical Features
• Yves-Bernard André continues as a part of the ownership team and remains Chief Designer of
all YBA products from his studio in France
• Yves-Bernard André sources critical components from France to YBA specs - transformers,
capacitors, wires, terminals, fuses, solder
• Manufacturing of chassis & final assembly performed in ISO9001 facility
• Yves-Bernard André directs & manages all YBA manufacturing & assembly in Shanling’s certified
“ISO 9001” facility to ensure the highest level of world class construction
• Yves-Bernard André personally tests all Signature series production and, if required, adjusts
to his design specs
• Two year warranty - any required servicing is done by tmh audio’s US-based Authorized
Technician
The New YBA
YBA's α-Class A
--- "alpha Class A" ---
Yves-Bernard André:
"The power supply works in class-A, but the output stage delivers only the power required by the music signal."
"Therefore, you have the sonic quality of Class A operation — linear output with current on demand —
without the negatives."
"Therefore, our amplifiers run cool, which improves reliability and avoids thermal stress on the components and the resultant parasitic vibrations."

Yves-Bernard André:
In fact many people think that class A sound is better because less distortion.
In fact, it is not the real reason. I state and tested 3 main reasons:
1. The memory distortion coming from the variation of temperature on the output devices, giving different curves.
In fact a transistor with a small signal has a curve and with a big signal another one, because its inside temperature will change from 30°C to 100°C very rapidly. We can then easily imagine that this has an effect on the sonic result and a non linearity. Until now, nobody took care of this phenomena.
2. In class A, the output stage is active always sucking current and then, the power supply is working always, particularly the rectifiers which are working in there linear portion. This is the important factor and not the distortion at the output stage. YBA finds a way to follow this aspect in his design.
3. The big disadvantage of heat dissipation in class A is the reliability, which is divided by a factor 2 each increasing of 10°C of the temperature.
In fact YBA claims to have the advantages of class A without having the inconvenient. Same for Class AB. YBA has the advantages of both classes: smooth and dynamics. Dynamics does not mean loud, but respect the life of the music.
The result is that we can listen at lower volume and keep the tonal balance of the music.e
