Esoteric D-07 D/A Converter and Digital Pre-Amplifier that I purchased new from an Esoteric dealer in August 2010. It has about 80 hours of use on it and is in perfect mechanical condition. Cosmetically it is perfect except for one very faint mark on the top of the unit towards the front that you will not notice unless you look closely, hence my 8 out of 10 rating for this unit. It has been a great DAC for me, I used the USB input with a MAC Mini server and the Amarra player with great results. As is usual with all Esoteric equipment the build quality is exceptional as is the sound quality in my opinion. The only reason I am parting with it is I am going to take the plunge with some dcs equipment and therefore will no longer need this DAC.
It comes with all of the original documentation and double box for shipping. It does not have a remote as I did not order it with a remote.
You can find find reviews of this DAC in Stereophile.
The following information on the Esoteric D-07 DAc is taken from Esoteric's website:
32-bit D/A converter model D-07 that supports the playback of Super Audio CD, CD and high-resolution, hard drive based music files.
The D-07 is a dual mono D/A converter capable of 32bit resolution throughout the signal path.
The D-07 features a variety of digital inputs, including a USB terminal, that support the playback of Super Audio CDs together with ESOTERIC's Super Audio CD Transport products, as well as the playback of high-resolution music files. The D-07's USB input can accept native resolution up to 24bit/96kHz.
The digital processing in the D/A conversion input is realized by utilizing a variety of D/D conversion functions, and thus represents the pinnacle of ESOTERIC's digital processing technology. The new D-07 features high-definition functions that employ state-of-the-art technology, such as format conversion for converting PCM digital signals to DSD, PCM up-conversion (2x/4x), and two digital filters (Including "pre-echo" reduction). These functions can be freely selected and used to fit your needs.
WORD SYNC allows you to synchronize playback with other digital devices, and a 2nd PLL effectively reduces the jitter for digital devices without WORD SYNC - these are the kind of high-definition functions that can only be found on high-end, specialized devices.
The D-07 also has an attenuator for controlling the level of analog output. This can be combined with selector functions that are used for a variety of digital inputs, and allow the DAC to serve as a high-end digital preamplifier.
The D-07, which can be used with both audio-visual devices and the PC, maximizes the potential of ESOTERIC's state-of-the-art technology. It is the ultimate high-end D/A converter for people that demand the utmost in quality for high-resolution music sources.
