@prof I admit that my friends and I are either lazy in your opinion or don't care to measure/take scientific accounting of why our equipment is sonically different from other equipment (cables, tweaks included). We don't care when we feel it is better/more enjoyable. If the change is worse, we unplug and disown it.
I read measurements when available. One of ASR's long time members writes how he loves Von Schweikert speakers and now owns the VR5. I don't recall many published measurements of his past or current speaker (or any of the VR5). There are several published reviews sans measurements. That didn't stop him from purchasing it and loving it.
