The new titanium oxide tweeter also affords improvements, John Giolas explained. "It's sweeter and more resolving, and has an even lower noise floor, making it the perfect companion to the new midrange."
The new drivers necessitated a new crossover for the Alexandria, with the result, Giolas said, of even greater authority and extension in the bass—a result of Wilson's ability to hear "…
The Supernait's unusual preamp section accommodates six analog inputs and five digital inputs via its built-in DAC, which handles sampling rates from 32kHz to 96kHz. Digital inputs include two S/PDIF coaxial, two TOSlink (which Naim suggests are "ideal for connection to a computer . . . with perhaps a dirtier-than-normal power supply, as the optical connection isolates the two separate grounds"), and a…
The tweeters and midrange drivers, followed by the crossover, and, on the 807 and 809, the ports are now downward-firing rather than front-firing.
"I re-radiused the flare of the midrange driver," Gøbel explained. "This made the driver stiffer at the voice-coil and more compliant at the surround. The driver, technically speaking, is somewhat less pistonic at frequencies outside its range, but more linear within it.
"I also…
To test the system further, I played the…
