Peachtree Audio Nova 125 Stereo Integrated Amplifier Gloss Black - 1 only to clear
"The Nova is no mere integrated. It includes a DA converter which most competitors don't.
To test the secret weapon, I switched to one of its digital inputs and let the Logitech Transporter supply the ones and zeros.
While nothing in the previous paragraph turned sudden lie, sonic changes immediately manifested as deeper colors.
Bass and treble gained presence, staging moved forward and also expanded laterally. Now there was more life in the music" - 6moons.com
Nova is the answer if you're looking to improve computer based streaming audio to a"high end" performance level; or if you just need a new millennium integrated amplifier.
The Nova is a world class 120wpc integrated amplifier with enough digital and analog inputs and outputs to satisfy all the new digital devices, plus, it can handle a few of the old dogs like turntables (w/external phono preamp), tuners, etc.. It performs much like a high end integrated amplifier because that's what it is.
The pre amp section employs a 6922 tube with a Class A output stage. This maintains a high level of detail while taming harsh compressed digital music. We couple that with an A/B amplifier in the final stage to achieve a very analog sounding product.
The Nova has a USB input for your computer in addition to 2 coax, and 2 optical inputs for other digital sources like Squeezebox, Apple TV, Wadia iTransport, Airport, Sonos, and XM or Sirius tuners. It also has 3 analog inputs for docking stations, CD players, tape decks or phono preamps.
If you want to add a subwoofer or outboard amplifier, the Nova features a "Class A"variable preamp output and a fixed line output. Nova covers all the bases like no other product before it.
Digital to Analog converter: Maybe the most unique Nova feature is the onboard ESS 9006 Sabre DAC. It's a 24/192 upsampling D/A converter, which transforms just about any digital source to the performance of a high end CD player.
The ESS Sabre DAC's patented jitter reduction circuit re clocks the digital signal to almost 0 jitter before passing it through a high resolution 24/192 upsampling processor that's also capable of 122dB s/n ratio. This is unheard of in any D/A converter until now and out specs anything from any other DAC on the market.
But the DAC chip is only part of the story because the surrounding electronics are extremely important. The Nova employs 11 regulated power supplies for the DAC and transformer couple each digital input stage so noise associated with ground problems and switching power supplies is eliminated. The USB connection is very unique. It is galvanically isolated from the computer connection. This is very important because significant noise generated by the computer's switching power supply travels down the USB ground and manifests itself as a major source of jitter. The Nova eliminates it before the DAC sees it.
The bottom line is we know of no D/A converter on the market at any price that will better the Nova ESS D/A converter in bench tests and to our ears. To match the performance of the D/A alone would be much more expensive than the price of the entire Nova. These are lofty claims, but can be backed up by the technical specifications and listening tests. The gauntlet has been dropped.
