If such techniques can credibly result in a desired sonic performance, then the current audio engineering cannot claim to possess the only truth. The quote, in a way, undermines Peter’s and AN UK’s own efforts: Why invest so much time and resources in R&D given the absence of any hard scientific evidence of its effectiveness? On the other hand, Peter proves his point by having confidence in techniques that seen from the perspective of current audio engineering, are highly unconventional, controversial even. Peter Qvortrup, the father of Audio Note UK, summarized pretty well the feeling of many audiophiles when he told me: “In audio, the failure of our “science” to square the circle between providing any consistently realistic musical experience with equipment that perform well under the steady state measurements that the audio industry applies to the design of its products, has undermined the validity of the science used, but no attempts have been made to develop a science that is closer to the sonic end results it yields.” If audiophiles are asked, the problem lies not in their head but in the current audio engineering and in its impotency in providing us with a believable theory of the relationship between various technical solutions and the perceived sonic characteristics. But it is so against personal experiences of thousands and thousands of audiophiles and hobbyists all around the globe, and epistemically those views must count too as empirical evidence. According to them, what explains the putative sonic differences between amps and DACs is not facts about their technical properties but natural facts about their listeners such as their psychological dispositions and mental states. For him, all amps and DACs are technically speaking (as specified by standard measurement procedures), if not identical, at least sufficiently similar to make sonic differences non-existent or at least irrelevant to human hearing. A mainstream audio engineer does not recognize the problem. The problem is that no one seems to have full understanding of how the technical characteristics would explain and predict our making the sort of sonic evaluations we make. If the sound really is different, it must be because the devices differ on the technical level. If it didn’t, two amplifiers or DACs that are identical with respect to their technical properties, could be judged to have different sonics. Why is this a problem? It’s a problem because the two must be connected, and the latter must somehow depend on the former. It is puzzling how our factual statements about the techniques used in amplifiers, DACs etc., and our evaluative judgments of their sound live isolated, self-sustained life. This E元4 amplifier has evolved over the years to a stunning piece of kit – The amazing thing is that the amp is absolutely dead quiet for a very powerful 35-40watts.Motto: Audio engineering is a very soft science, what Comparison by Contrast does is harden it a bit until such time when we are able to work out how to measure the differences we hear and create an overview. The pure E元4 35w stereo power amplifier version which is just the main E元4 Board with driver ecf80 and power supply, with no pots or selector switch and a flat front faceplate.An integrated stereo amplifier with the additional 12au7 buffer board, volume pot and selector switch.The E元4 stereo amplifier is available as either: ![]()
