LAB REVIEW

We were very skeptical of the Dragonfly DAC. How could this measure up to the traditional metal box DACs we're used to? We plugged it into our iMac and we were instantly convinced. The Dragonfly drastically improves the sound quality of your computer output... not by a little, but by a lot. Not only was the output much louder (we had to lower the computer volume considerably), the sound was obviously fuller and brighter. 

And at the size of a USB stick, the Dragonfly is built for the modern lifestyle. Plug it in to your desktop and forget that it's there, or throw it in your laptop bag for portable audiophile sound.

The Dragonfly works by bypassing the poor sound quality of your computer's audio card. It utilizes sophisticated electronics (centered around a 24-bit ESS Sabre™ conversion chip, a high-performance solution that’s typically found in better CD and Blu-ray Disc™ players); reduces timing errors (which gives it that fuller, more natural sound); and optimizing the output in direct relation to the native (original) sample rate of your music file.

TECH SPECS

• Variable Output Drives Powered Speakers or Power Amp
• Fixed Output Feeds Preamp or Receiver
• Asynchronous Transfer Ensures Digital Timing Integrity
• Two Clocks Enable Perfect Native Resolution at 44.1kHz, 48kHz, 88.2kHz and 96kHz

LAB REVIEW

Bellari's VP-530 is the first high quality tube phono preamp with built in USB out so you can record your vinyl to computer with a tube amp sound (known to be warmer and more musical than that of usual solid state amps). The unit employs a sophisticated Burr-Brown PCM2901EG (16-bit, 44.1 kHz) chip in a smartly designed Bellari circuit for superior digital/analog conversion. It also is the only phonopre that gives you the option of by-passing the RIAA curve if you want to do your own EQing, and also features a built-in headphone amp with 1/8" jack, and a rumble filter switch. Recommended.

MANUFACTURER'S REVIEW

High gain version of Grado's RA-1 Headphone Amp.  The RA-1HG is designed to drive headphones with impedances of 100 ohms or more, so audiophiles can enjoy the RA-1's sonic qualities with a wider selection of headphones, (though this sounds best with Grados). This amp is machined from a solid block of mahogany and measures 5" wide, 5 1/2" deep and 1 1/2" tall and weighs in at 12 oz. It is an AC version powered version that will guarantee hours upon hours of listening pleasure. And the sound? Just like all Grados: warm, smooth, full-bodied, non-fatiguing and rich. Hook it up to any line source (portable or in-home) and drive your headphones to their full potential.

Simple Materials

The Ceramic Speakers are made from porcelain, cork, and Baltic birch. Each material is minimally finished, left to add its natural beauty to the design. The included amplifier is made from stainless steel sheet metal, with a cast iron base and paulownia volume slider. Aside from the electronic components, plastic is completely avoided in the system's construction.

Intense detail

Typical speakers are designed to play even the most compressed or poorly recorded track. They gloss over the details that give high-resolution music its depth. The Ceramic Speakers' custom-made drivers, porcelain and cork enclosures, and Tripath amplifier reveal every nuance. They will show the difference between lossless and mp3 files, and will unlock vinyl's richness.

Never Proprietary

Binding posts, 1/8" jacks, and banana plugs have been perfected through years of electronic design. It would be arrogant to replace these simple, effective standards with proprietary connectors. Due to their open design, the Ceramic Speakers work with nearly all high-quality components. The terminals also have a utilitarian beauty that the design emphasizes rather than hides.

MANUFACTUERER'S REVIEW

We significantly upgraded the award winning dac25.2 to the dac25.3. The upgrade was to the USB input which now accepts 24bit/96kHz signals. The dac25.3 is natively compatible with Windows 7/Vista/XP/2000 and Mac OS X. Today an increasing number of music lovers are buying storing and listening to music through their computer, media server, or personal music player (iPod). Many are also digitally distributing their music using a sonos, squeezebox, or one of a host of digital music distribution systems available on the market. This is a great way to explore and appreciate music but generally it's done at the expense of sound quality. Until now music lovers have been forced to rely on the inferior digital to analog converters (DACs) and sounds cards contained in those devices. As a result, their musical enjoyment has dramatically suffered. We designed the dac25.3 to directly address this problem and to significantly improve the sound quality of the music played on these systems.

By uniting a state of the art digital to analog converter with a tube output we produce the clarity and precision of a 24bit DAC with the warm rich open sound people love of tubes. The dac25.3 has 4 digital inputs which can accept any coax (s/pdif), optical, XLR (AES/EBU), or USB digital input from an iPod transport, computer, media server, sonos, squeezebox, CD/DVD in stereo transport, or music hall's own cd35.2 compact disc player, and it will output two channel stereo analog.

The dac25.3 features the latest texas instruments (formerly burr-brown) PCM 1796 24bit/192kHz, advanced segment, stereo audio digital to analog converter. This processor features 123dB dynamic range an 8 x oversampling digital filter and just 0.0005% thd. The dac25.3 upsamples to either 96kHz or 192kHz which is user selectable on the front panel. To achieve the best sound we use an advanced asynchronous reclocking and anti jitter control system upstream of the PCM 1796 DAC. For this system we are using the philips 74HC574 in conjunction with the ti SRC4192 asynchronous sample rate converter whose master clock is a high precision active crystal oscillator. The dac25.3 also features a large r-core high current oversize power transformer. A headphone output is provided for convenient personal listening.

LAB REVIEW

Don't let the simple exterior mislead you. The Fono Mini A2D is an award winning preamp at an excellent price. In addition to the quality Rega sound output, this preamp offers both traditional RCA outputs and a USB output for digital recording (for software, we recommend Audacity). Unlike many preamps at this price range, it also features a level output control which is extremely useful for creating the best recording. Recommended.
