Meni Linn zvuči bolje od Naima koji je A/B-klasa.
Linn ne spominje D-klasu:
Chakra Technology

Patented amp technology combines the speed and precision of monolithic chip with the robustness and smoothness of bi-polar transistors.

Chakra constantly adapts by using a monolithic at low currents and bi-polar transistors at higher levels. It's a unique approach to transition between these technologies, guaranteeing precisely-controlled clean, silent power at all listening levels.
Također, Wadia ima D+ klasu i zvuči tako toplo i meko da bi moglo proći kao cijevno pojačalo.
Također, Arcam ima G-klasu koja nije ništa drugo doli A/B-klasa smanjene potrošnje i grijanja.
N-klasa pojačala.
