-- 151PowerDAC mini Delivers Legendary D/A Conversion plus Digital Amplification in an Undersized Package with Oversized Performance --

To complement the hugely successful 170i Transport, Wadia has developed new technologies that enable us to once again bring simplicity and elegance to a new and dramatically more affordable Wadia decoding product – the Wadia 151 PowerDAC mini (SRP: $1,195). The Wadia 151 takes all of the conceptual purity of the original Reference PowerDAC and reduces these elements to their most cost effective form.

The musical performance is immediate, precise, and pure,” commented John W. Schaffer, President, Wadia Digital. “No other digital to analog conversion product offers this level of decoding accuracy combined with amplification in a single, simple to use, modestly priced product.” “The 151 PowerDAC mini has realized the goal of a direct connection between your music and your speakers.”

The 151 PowerDAC mini measures 2”x 8”x 8” (H/W/D); making it an ideal audio solution for modern living and work spaces. Wadia incorporates two SPDIF digital coax inputs, one Toslink input and one USB input for easy connection with most computers and digital sources. Rated at 50 watts (4 ohms), it has the power to drive many currently available speakers. With an LED Backlit Display, volume control, mute, phase and input buttons on its face and an IR remote control; the 151 is elegant in its simplicity.

Added Schaffer: “For over 20 years, Wadia Digital has been analyzing and researching every feasible way to improve digital conversion, with the goal of providing the best possible musical and emotional experience from digital audio source material. The significant legacy of patents and innovation is among the most important and proud aspects of Wadia history.”

Wadia Digital’s 151 PowerDAC mini will be shipping in Black and Silver finishes for Fall 2009 and will be available at select high-end audio specialists – www.wadia.com.

The SkyFi Testing Process for Solid State Amplifiers:

We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage.

We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally, we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If everything reads clean, we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier then remains powered on to "burn in" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will be also be tested.

Final testing involves pushing actual music thorough the amplifier. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage KEF speakers that we're very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice.
