Impact of phase inversion by preamp
This will be my first post on this forum so I thought I’d pose a question I’ve always wondered about. I have a Conrad Johnson Premier 18LS preamp that I’ve been extremely happy with since first acquiring it some years ago. This is a solid state single ended, single stage design that inverts the phase of the input signal at the output. The manual states that you should reverse the connections to the speakers to account for this. Obviously this is easily done but I really can’t see how it would really matter as long as things are connected consistently between the left and right channels. I’d be interested to hear what others have to say on this subject.

@rsf507 - That seminal treatise(The Wood Effect) is mentioned in each of the articles, I referenced above. In the first listed Stereophile article; contained in a somewhat blistering response. The very first article also posts a list(at the end), of some CDs and their relative phase(with the majority of players out there), as well as a few CDPs/DACs and their phase output, which may be of some interest. |
The Wood Effect. Looks like only used copies available https://www.directtextbook.com/isbn/9780929383002 |
