To mi je padlo v oko pri doslejsnjem pregledovanju:
First, what is it? It's a hybrid integrated tube/solid state amp with 3 analog inputs, 4 digital inputs and 1 USB input . The amp puts out 75WPC and it even includes a headphone amp and a preamp output, so a subwoofer or more powerful amplifier can be added at any time. Nova's preamp section uses a 6922 tube with a Class A output stage, which maintains a high level of detail and also provides a sonically richer platform to tame the harshness that plagues most compressed digital music.
Sound good so far? The real performance piece here however is the DAC; an ESS 9006 Sabre DAC, a high-resolution 24bit/192k up-sampling converter that reclocks the incoming digital signal removing harmful jitter before passing the signal to the 24/192 upsampler with it's 122dB S/N ratio! We all know power supplies are important. even great circuits driven by a weak or cheap power supply will be compromised. The Nova sports - ELEVEN - regulated power supplies for the DAC and digital section transformer-couple each digital input stages.No switching.
The USB section is a bit different than most implementations found on the market; the Nova's USB connection is isolated from the computer's power supply and therefore the noise generated by that system. This provides a cleaner, quieter signal to the DACs offering greater resolution and more music! The Nova's powerful 75WPC amplifier is backed up by a huge toroidal power supply. "The DAC in the Nova is one of the best in the world. We encourage reviewers to compare it to any other DAC, even those costing thousands more", said Sol oman
For those Headfiles out there, the Nova has a “Class-A” tube headphone amp inside, not the usual op amps we usually see. The Nova is available now for $1,200. David is sending us one for review.
