Thank you Karen for your opening article. Another aspect of the audio listening chain is the recording process. I have been building up a small recording label for the last 5 years but by day I am an associate of Vivid Audio loudspeakers and before that I spent many years with Bowers and Wilkins in the research department back in the early 90s. In one way or another I have had a professional life in Audio for 35 years and before that an amateur one going back till I was old enough to switch on the radio-gram. I spent time in my 20s in Abbey Road recording studios and field recording too, on Reel to Reel and DAT when it came along. I also play the piano and the pipe-organ and listen to a lot of classical music.
To cut to the chase - when we desire to listen to music at home we have the music itself, which was recorded from live musicians, or electronic synth, or studio, miked, multi-tracked, mixed, listened to through monitors that range from dire, average to, with a few exceptions, brilliant, by producers on a time and budget schedule and engineers who listen too loud, all passed through ordinary balanced cables not audiophile ones, and then cut to a lacquer for LP processing digitally or by analogue (and if so via tape to tape to tape copies, Dolby systems etc), through a whole load of processes, or stamped to CD / SACD. So by the time your music gets to your turntable or CD player (or streamer and all its codecs and compression) the music from the mic to your HiFi has had a pretty torturous ride. Hence the vast difference in recordings there are out there, ranging from the superb to the excruciatingly awful.
THEN we have the multitude of variations in HiFi equipment till the signal gets to your speakers, which, are the last component to mess up your audio before your room does! Is it any wonder there is so much to go wrong, before it goes right? Karen has already detailed that side of things.
Hence the reason I decided that I had to control the recording stage as well as the reproduction stage, and use the VIvid Audio system as a reference, with reference quality microphones and a very simple digital system to do the conversion process, or straight to Reel to Reel as another option. Then you can complete the circle, and really get to hear what is possible. There are quite a few of us who do this of course, but not many who are part of the recording and reproducing chain like I do. Usually they are totally separate entities and don't talk to each other much. Just like TV production companies don't make television sets - with the exception in the old days of Sony - who made the entire chain from cameras to video recorders to Television sets. But I believe that is gone now.
