I’ve had someone more professional than I come in with a test CD and measuring devices to calibrate my system and adjust settings along with the speaker placement but there are some CDs that just don’t sound as good to me where the speakers are. It may very well be a bias with what I prefer to hear, or a flaw in the testing conditions whereby the test CD doesn’t accurately reflect the distribution of frequencies and audio wavelengths found in the difference CDs I listen to. In other words, I’m sure the placement and settings are ideal to listen to the test CD!
In the end, what matters to me is how I prefer to hear the sounds from each CD from wherever I am sitting or standing at that moment, however inaccurate they may be! That certainly is hypocritical I admit because after all, I love the Thiels for their accurate representation of the material. Could be that I’m ignorant, lazy or just simply human! I am not perfect, despite what I tell my kids.
