FREQUENTLY ASKED QUESTIONS

Should I use a Balanced or Unbalanced connection?

If your amplifier has a true balanced input, we recommend you use the balanced analog output from your Wadia 861 Compact Disc Player.

All things being equal, properly implemented balanced (also called differential) circuitry sounds better than unbalanced circuitry. The Wadia 861 is a true balanced design. It generates the inverted signal in the digital domain and all subsequent processing is done in balanced mode.

Your Wadia 861 is designed to maintain many of the advantages of true balanced design when using the unbalanced outputs. In addition, the Wadia 861 output stage is capable of driving both types of out- puts simultaneously.

Why should I bypass the Preamplifier?

A preamplifier is unnecessary when using your Wadia 861 Compact Disc Player. The Wadia 861 provides all the necessary control functions of a preamp while the signal is still in the digital domain. This avoids the sonic degradation caused by analog circuitry, switches, and wire. The Wadia 861 output stage can drive any power amplifier and any interconnects, even very long lengths.

Does the Wadia Volume Control compromise resolution?

The Wadia 861 uses the latest generation of Wadia’s proprietary digital volume control.

The volume level can be varied in the digital domain by means of mathematical manipulation of the signal, eliminating the distortion and noise that are inevitable with even the best analog volume controls. While conventional thinking indicates that reducing the volume digitally can sacrifice low level resolution, Wadia has created an innovative solution. Wadia’s patented digital filtering algorithm produces a 24 bit output rather than the 16 bits stored on the CD. This high-resolution signal is then used in the computations which in turn reduce the volume level. This new signal is fed directly to the DAC chips. Through this innovative method, the Wadia 861 maintains high resolution even at the lowest volume control settings.

Can I bypass the Wadia Volume Control?

Because the Digital Volume control does not include any analog circuitry, there is none to be bypassed. Even the mathematical program step that performs the Digital Volume Control calculation is an integral part of the Wadia DigiMaster filter algorithm and therefore cannot be bypassed.

If you do not need the Wadia Volume Control, set it to its maximum level of 100 on the display.

What about Analog Sources?

In order to fully realize the potential of this type of system, Wadia has a range of Analog-to-Digital converters. Now it is possible to use analog sources, such as a tuner, tape deck, or even a turntable (in conjunction with a suitable phono stage) in your system without using a conventional analog preamplifier. Consult your dealer for more information on the Wadia Analog-to-Digital products.

Should I leave the Wadia 861 with the power on?

The Wadia 861 is designed to be left with the power on with no harm or wear to the unit. All motors and laser circuitry turn off when the unit stops playing. If desired, the front display can be turned off (see Turning off the Display under Remote Operation). Leaving the power on allows the circuitry to remain in thermally stable, which provides better performance and longer life. Careful listeners will notice that the sound of the Wadia 861 will improve steadily after the unit is powered-up. A new unit will undergo more dra- matic changes when power is applied for the first time. If you turn off your Wadia 861 for more than an hour, you will find that the unit will undergo similar, but less dramatic improvement once power is reap- plied.

861 specifications

Wadia Digital has long been recognized as a pioneer in high-end audio equipment, and the Wadia 861 is no exception. This CD player, first introduced in the late 1990s, has carved out a noteworthy reputation in the audiophile community for its exceptional build quality and sonic performance.

One of the standout features of the Wadia 861 is its proprietary Digital to Analog Converter (DAC) design. The unit employs a 24-bit/192 kHz DAC that delivers an extraordinary level of detail and clarity. This high-resolution capability allows the Wadia 861 to reproduce audio tracks with a depth and richness that many standard CD players cannot match. The DAC is complemented by Wadia’s unique DigiMaster technology, which is responsible for precision digital filtering, contributing to the player’s ability to deliver a clean and natural sound.

Another noteworthy aspect of the Wadia 861 is its construction. Built with a robust chassis, the player minimizes resonance and vibration, providing a stable platform for the sensitive internal components. This attention to physical construction ensures that sound quality is not compromised by external interferences. The elegant design also embodies Wadia’s commitment to aesthetics, making it a visually appealing addition to any high-end audio system.

The Wadia 861 features both balanced and unbalanced output connections. The balanced outputs are particularly advantageous for those looking to integrate the player into a sophisticated audio setup, as they help to eliminate potential noise and maintain signal integrity over longer cable runs. Additionally, the unit has digital outputs, giving users the flexibility to connect to external DACs or processors, further enhancing its capabilities.

Moreover, the Wadia 861 supports a range of digital formats. While it is primarily designed for CD playback, its advanced technology ensures that it can effectively handle various digital audio signals. This versatility broadens its usability, accommodating various audio setups, whether through direct playback or as part of a larger digital audio chain.

In summary, the Wadia Digital 861 remains a benchmark for high-fidelity CD playback, thanks to its state-of-the-art DAC, solid construction, and superior audio output options. Audiophiles seeking an enriching listening experience find the Wadia 861 to be a remarkable investment, showcasing the perfect blend of technological innovation and classic craftsmanship.
