Green Mountain Audio Chroma HX

I just upgraded from the chroma 2 to the HX version of the GMA RIO . The results were amazing!! much better cohesion across the frequency spectrum . The detail was also improved. I have owned many highly rated speakers and none of them come close to the overall musicality of the RIO HX.

I have  been listing to my GMA RIO hxs that received the GMA new burn in treatment  for the crossovers. This treatment  is even more of an improvement  in the sound than the chroma hx upgrade was. They now blow away any of the many good speakers I nave owned over the past 40 years. The improved  detail and musicality result in far more enjoyment in listing to my cds and vinal. They are more musical than any of the systems I heard at  the Oakland  hi fi show recently. Everyone  who hears them is blown away by their sound. Many thanks to Roy Johnson and his expertise in speaker building.

 Thnnks again !
