To all readers I am a dedicated audio systems builder for some 30 years now, I have seen and heard pretty much everything in the industry, this new Loudspeaker from
Nsr Sonic Research D-3 Sonata is a Brekthrough product .
The simplicity of the crossover with only 2 capacitors in the signal path of 4 drivers is a worthy accomplishment.
The patented sealed APL-Acoustical projection lens is
superb in it's articulation and lack of bloat even at the lowest of notes room dependant of course,also the Xover uses all quality parts such as Auricaps CAddock or Vishay resistors,. The Reference Xover is as good as any in the World it is a $900 upgrade using the Hand made Dueland
resistors and Copperfoil vsf capacitors which take 8 days
per batch to make and sonicly the best by far,the inducors are the superb Solen Hepalitz ,with custom multistrand wiring.These speakers are so refined that I feel they easily compete with any at 2x+ the price and I welcome anyone in the area to come have a listen .there are several reviews in the works .if you are thinking about buying a new speaker please don't overlook this transducer it would be a big mistake .even the standard model is now at least 15% better than the show examples that received many praise at the shows.
I thouhght it was my obligation to set the record straight on pricing and misinfomation thankyou. http://www.Hifidelityaudio
