La prueba se realizó en igualdad de condiciones, stands, cables de parlante e interconexión standard de alta calidad, amplificación adecuada (Krell S550i), fuente (Mac mini) y DAC (Pro-ject RS). Se igualaron niveles con ruido rosa grabado a un nivel de -10 dbFS, con un nivel de 85dbSPL a 1m de distancia de cada caja, medido ésto con sonómetro con ponderación A. El material de escucha constó de varios temas de diversos géneros extraídos de CDs originales en un sólo track sin tocar el nivel original en ningún caso (Gracias GastónP!).
Cada participante pudo evaluar a su criterio los diferentes puntos y se calificó de 1 a 6.
Resultados Generales:
Los precios mencionados en los siguientes gráficos, así como en el detalle de cada modelo de cajas, corresponden a los recomendados por los fabricantes como precios de lista, en los casos de los modelos discontinuados, corresponden a ése mismo precio en el momento de su fabricación.

De acuerdo a lo conversado entre varios de los asistentes a la reunión, era importante saber qué pasaba con la relación precio/prestaciones de cada una de las cajas, punto que no estuvo en la propuesta de evaluación. Consideramos que éste es un dato no menor a la hora de poder evaluar un cambio o acceder a un primer juego de cajas.
Esperamos los aportes de quienes estuvieron en la prueba ya que enriquecerán el hilo y aportarán data a quienes busquen en un futuro un upgrade y tengan al menos alguna guía para poder consultar.
