How Long Should One Wait Before Switching When A/B ing


Evening All,

          Ive been having quite an indepth and somewhat involving on going disscusion with an audiophile aquiantance regarding what would be considered the "Ideal" waiting time before one should switch from one component lets say,to another to actually appreciate in its entirety,a devices personal signature,Nuances,or its overall sonic portrait..One against the other.Its been said that our auditory memory as far as retaining information on a whole is in effect the poorest of all our faculties.This individuals personal school of thought is that you should give at least a solid week of listening to a given peice of equipment,and than and only than,switch to the "Other" device to be able to fully appreciate this phenomena of A/Bing,and capture all the information that each individual components features may or may not be readily available to us! I,on the other hand,beg to differ of this approach.Soley basing my self of this "Limited Auditory Memory" we all have! So my findings and resolute conclusions on which component do what,and how it will behave being compared one to the other,will in MHO be discovered in a matter of an hour,or maybe two.Switching from one to the other all the while! I firmly believe that THE component in question that is to be evaluated against another will not reveal themselves more in lets say a weeks time,than when you first did the initial A/Bing that first day you began this process of possible illiminations or the reverse for that matter!

I wholeheartedly invite whomever it may be to share your own experience on this matter.

@zyac39 Having performed several auditions, mainly of cables/connectors, the one thing that makes A-B ing very difficult is the fact that the connectors on cables need to "seat" (or settle) before providing their best perofrmance-

The settle time is different form cable to cable, but can be as much as 24 hours.

I do not know if this is the same for components (assuming the components are both burned-in), but he fact that you have to connect them with cables would seem to imply this should at least be considered.

How did I approach this...
- first, find suitable audition tracks and listen intently for "cues" in the music that can be easily recognised.
- a cue might be a cymbal strike, or a particular bass phrase or the dynamics of percussion instruments.
- I document each "cue" with my existing cable/connector
- listen to the second cable/connector and note differences in each of the cues
- I then go back to the first cable/connector to see if you can identify any further differences.

Most of my auditions of new cables/connectors were conducted over many days and after long periods of listening to the "existing cable" in my system.

In the early days I just listened for easily identifiable metrics - like brightness, bass depth and control, image etc... but as the auditions progressed onto higher end cables I ffound myself listening to extremely finer details like the subtleties of the acsoustics of the venue (live recordings) like the reflections of sounds within the venue and the noises generated by the musicians - even the sounds sometime captured of noises outside the venue.

I have around 60 audition tracks containing all genres of music and I listen to them frequently just to keep the cues at the forefront of my memory

Hope that makes some sense - Steve
