A few additional thoughts for
@fuscobal on getting as much useful information as is reasonably possible from the audition process:
1. Use music that you know well and that is representative of what you normally listen to, whether or not it's "audiophile approved." Your approval is the only one that matters.
2. Listen with closed eyes. The less brain power you're devoting to processing visual information, the better you can concentrate on listening deeply into the sound quality and spatial quality.
3. If you like what you are hearing from the speakers so far, this next listening test is usually pretty good at predicting whether they will give you fatigue-free listening over long listening sessions, because sometimes you may not have time for a suitably long listening session during the audition process. It's called the "L.I.A.R." test, and that stands for "Listening In Another Room":
Turn the volume level up louder than normal and walk out of the room. Listen through the open doorway but with no direct line-of-sight to the speakers. All you'll be able to hear is the reflections and their dynamic contrast. If it still sounds good, and still sounds a lot like live music, through the open doorway, ime that is a good predictor of long-term fatigue-free listening. This test will not work if the room has been heavily treated with sound absorption, as that will remove too much of the high frequency energy.
4. If something sounds obviously wrong, give that a lot of weight. One of the take-aways from the controlled blind listening tests conducted by Harman under the supervision of Floyd Toole is this: The most highly preferred speaker is not necessarily the
most virtuous speaker; rather, it is the
least-flawed speaker.
