It is easy to overlook the influence of a recording engineer, and their sitting at a consul with an artist/artists bringing the work to the place where it is felt it conveys energy that is the most revealing of the story / message being presented. There is a relationship between artist and engineer, and when the artist can yield and give up their control and allow the engineer to bring in their own flair, is where magic is to be discovered in a recording.
I have over the years concluded for myself, that when the recording was being experienced as a replay for being at its most articulated, was the same as being in the studio with both engineer and artist when they were generating the wanted impact for the performance, both artists and engineering have been in parity in bring a creative content.
I am confident on many occasions when using and being demo'd certain designs for a Analogue Source. I have been hearing the Performers contributions assembled to create the recording. What is missing is the influence of the engineer on the performance, which is perceivable as being withheld remaining under the surface. This as an experience does not prevent in any way a music encounter that is not to be enjoyed. It is just that when the overall experience is supported with an experience only describable as being very very honest and aligned to the intention for the production, this as the perceived experience has substantial attraction.
With an experience only describable as being very very honest and aligned to the intention for the production. Also brings into the equation a interest that sits comfortably in conjunction with the regular usage of the Source. An unavoidable fascination is to appear, being thoughts on how such a good impression can be eked to further betterment.
In my case and a few close friends having similar experiences, the fascination was all about the signal path for the produced signal and how it was transferred to the Phon', through the Phon' on to the Power Amp.
It is not a secret, that I am able to use a selection of ancillaries to receive the signal and create End Sounds. When the Source presents to a certain standard, versions of End Sounds are attractive over one End Sound, differences detected in the sound being formed become much less discriminated against.
