"A huge and complex system made ​​ingeniously simple and easily positionable in the environment. Designed by the great Renato Giussani."

"In a home-listening I believe that Delta 4 are good ... indeed... exceeding! And all this with a perfect balance."

"What is "missing" in Delta in my opinion it's something that "should miss", and that is that some emphasis on low frequencies that puts "in shadow" mid-high and sometimes makes it sound a bit 'confused (especially in full orchestra). was the "defect", so to speak, of 7/06. This "lack" I greeted with much pleasure, especially as combined with a "presence" of the mid-high range for amazing transparency, clarity and airiness.

"I am immediately struck by a mid-range "enchantress", which predisposes me to listen to more than the analysis of the sound."

''The 'Butterfly' paint a 'three-dimensional image where each instrument, perfectly distinct, emerges and finds its proper space, creating a very detailed sound, warm and full-bodied with every genre of music and often leaving the listener without words. For me the last word in standmount loudspeakers"

"The voice comes out as a clear and hovered in the air, fresh and vibrant. But above all does not seem to "come" from the speakers."

"The NPS-1000 is more than a large system, it is a real sound research lab, not only on design research, but even on aesthetic research for its user, such and so many are the new informations that the system is capable of detecting these and many are the spatial aspects that is able to rebuild. "

"It's hard to describe the experience with the Delta 4 R10 system and even to find the right words. I can guarantee that listening to these jewels will satisfy all points of view, impact, detail, low medium and high range of unique beauty."

"The music literally "fills" the room, all the instruments of surgical precision friends Donald and Walter have an amazing 3D effect and presence"

"That's something incredible! They look like electrostatic speakers 'with balls'"

"The contrabass is rightly deep, warm, clear and pleasant to listen to."

"The low notes of the Bosendorfer piano are difficult to reproduce with proper realism, so that, at trade shows, I didn't wonder more to listen to, precisely because I remained disappointed. Behold, finally I have found with the GR the "telluric" bass of a live Bosendorfer piano."

"What about ... The first word that comes to mind is IMPRESSIVE. The GR is a TOP loudspeaker system, that excites. "

You need just two essential things: the right and proper sound and Delta 4 R9. Turn on, sit down, clear your mind and get ready for a trip that you will never be able to do without it. Thanks Giussani.
