앰프제조기술이 그렇게 뒤쳐진 기술은 아닐 수도 있습니다. 일례로 앰프제조사인 Pass Labs의 앰프제조 관련 특허를 Texas Instrument가 구매했던 경우가 있었습니다. Texas Instrument라고 하면 대단한 첨단반도체 회사가 아니던가요?

참고로 저는 Pass Labs나 그 수입원과는 전혀 무관하구요 패스사의 제품을 프로모트할 의사도 전혀 없습니다만 너무 앰프기술이 평가절하되는 것 같아서요.. 글을 올려 봅니다.

Press Release from Pass Laboratories, April 10, 2006:



Pass Labs is pleased to announce that Texas Instruments has purchased a non-exclusive license to U.S. patent # 5,376,899. The amplifier topology, marketed by Pass under the tradename "SuperSymmetry" provides a means of achieving high performance with balanced symmetric feedback and minimal gain stages.



SuperSymmetry has been the basis for amplifiers marketed by Pass since the 1998 introduction of the X-1000, a 1000 watt power amplifier using only two gain stages - differential input transistors driving complementary power output transistors.



"The beauty of the design lies in the combination of power and simplicity. We believe that the highest quality sound is achieved with a simple gain path, and SuperSymmetry gives us high performance with minimal complexity and negative feedback", says inventor Nelson Pass.
