RE: Finally, an accurate amplifier...

I saw no perfection in the amplifier measured by JA. One can not conclude from measurements that a piece of gear sounds good. One has to listen to a system containing the device in question. One is still at risk of reaching the wrong conclusions as to the cause of what one heard. The measurements were far from perfect, as JA's equipment was showed.

If you want to convince me by measurements that an amplifier is transparent then I will have to be able to pick the source material. I will conduct a null test, comparing the actual output vs. the "correct" output. If the null tests shows that the error was -160 dB below the correct output measured with a 200 kHz bandwidth, then I might be convinced by measurements. (You will be responsible for providing the accurate test equipment. It might be available from the appropriate sources. I suggest going to the experimental physcists at CERN. They might be able to help you. I am talking far beyond Audio Precision. Test equipment needs to be 10x better than the device under test, and this is difficult with audio, where high end equipment is already at the state of the art.)


In the absence, I will just go with my ears. Why am I right and you are wrong? Because we are talking about audio amplifiers intended for listening to music, not laboratory instruments intended for conducting measurements.
